Pros
- Metal-free, non-conductive carbon microparticle formula, so a slip onto nearby SMD components will not short the board
- 4 g syringe covers roughly 15 to 20 desktop CPU applications at a pea-sized dot
- Manufacturer states an 8-year service life, so one application normally outlasts the build
- Continuous-use range of -50 to 150 C covers sub-ambient loops and hot mini-ITX cases alike
- Viscosity of 31,600 poise spreads under mount pressure without needing a spreader card
Cons
- No spatula or cleaning wipe in this variant, so you supply isopropyl and a lint-free cloth
- Grey compound stains PCB and fabric and will not wash out of clothing
- Conductivity trails liquid-metal compounds by a few degrees under sustained full load, which is the trade for being non-conductive
The 4 g syringe holds enough carbon-microparticle compound for roughly 15 to 20 standard desktop CPU applications, or fewer if you are covering a large heatspreader such as an AM5 or LGA 1700 lid.
- Density: 2.50 g/cm3
- Viscosity: 31,600 poise, thick enough to stay put yet still spread under mount pressure
- Volume resistivity: 3.8 x 10^13 ohm-cm, effectively an insulator
- Continuous-use range: -50 to 150 C
- Colour: grey
Stated service life is eight years, so a single application normally spans the whole life of the build. The formula has stayed the same across packaging revisions, and each tube carries an authenticity code you can verify with the manufacturer before use.
Strip the old compound first. Isopropyl alcohol at 90 percent or higher on a lint-free cloth clears both the heatspreader and the cooler base; neither item is included here, so buy them separately.
A pea-sized dot in the centre of the lid suits most square LGA and AM5 chips. Rectangular Threadripper and older HEDT lids do better with a thin line down each axis. Lower the cooler straight down and tighten the mounting screws in a diagonal cross pattern, a quarter turn at a time, so the compound spreads evenly and no air pocket forms in a corner.
Do not spread it with a card unless you are covering a bare GPU die, where a thin even film matters more. Any smear that reaches surrounding capacitors is harmless because the formula carries no metal, but wipe it away anyway to keep the board readable.
Because the formula is metal-free and non-conductive, it is safe on every socket type in current use, on bare GPU dies, on laptop heat pipes and on memory or VRM heatsinks. There is no risk of bridging pins on a shim-less die, and no galvanic corrosion of an aluminium cooler base, which rules out the two failure modes that make liquid metal risky for a first-time builder.
The trade is raw conductivity: liquid-metal compounds shift a few more degrees under sustained full load. For an air tower, an all-in-one loop or a console teardown, that gap rarely changes fan behaviour. Storage is simple too, since the compound does not cure inside the tube, so a partly used 4 g syringe stays usable for later builds if you cap it and keep it out of direct sun.
Pros
- Carbon microparticle formula is metal-free and non-conductive, so a stray smear cannot short a socket pin
- Volume resistivity of 3.8 x 10^13 ohm-cm alongside a density of 2.50 g/cm3 and a viscosity of 31,600 Poise
- Holds up across a continuous-use range of -50 to 150 degrees C
- A 4 g tube covers roughly ten desktop CPU mounts at 0.3 to 0.4 g each
- Plastic spatula included for spreading an even film on bare dies and rectangular heat spreaders
Cons
- No thermal conductivity figure in W/mK is published for the compound, so a direct spec comparison against rivals is not possible
- The 4 g tube suits a home builder but runs out quickly on a repair bench doing weekly rebuilds
- Surface cleaning solution is not included; the MX Cleaner is a separate item
The compound is built around carbon microparticles rather than metal oxides or liquid metal. Those particles fill the microscopic pits in a processor lid and a cooler base, replacing the trapped air that would otherwise sit in the gap and block heat flow.
- Density is quoted at 2.50 g/cm3 with a viscosity of 31,600 Poise, giving a firm but spreadable body
- Volume resistivity of 3.8 x 10^13 ohm-cm means it does not conduct electricity
- Continuous-use range spans -50 to 150 degrees C, covering sub-ambient loops through to a heavily loaded overclock
Because the formula is metal-free, paste that escapes onto a socket pin or a surface-mount component will not short anything, and there is no corrosion risk to a copper or nickel cooler base of the kind liquid metal introduces.
A plastic spatula is in the box, which matters because the consistency of this compound suits spreading as much as the single pea-dot method.
- Clean both mating surfaces with isopropyl alcohol first; the dedicated cleaning solution is sold separately and is not bundled here
- A central dot works for square heat spreaders, while the spatula suits rectangular lids and bare dies where an even film matters more
- Seat the cooler in one straight motion and tighten in a diagonal cross pattern so trapped air is pushed outward
There is no cure or burn-in period, so temperatures read true from the first boot. The compound does not dry out or crack in service, so a remount months later usually needs only a fresh clean and a new layer rather than scraping hardened residue off the lid.
Four grams sounds small but goes a long way on typical desktop hardware.
- A standard AM5 or LGA1700 heat spreader takes roughly 0.3 to 0.4 g per application, so the tube covers around ten CPU mounts
- A bare GPU die needs less, while a large workstation socket or a heat-spreader-free laptop chip needs more careful metering
- Leftover compound stores for years if the cap is refitted and the tube kept out of direct sun
For anyone repasting one machine every couple of years, this quantity outlasts the hardware itself. A repair bench turning around several rebuilds a week will prefer a larger tube of the same formula to avoid constant cap-fiddling. The included spatula is a single plastic tool, so a busy workshop will want spares of it.
Pros
- High filler content and a dense, viscous formula push heat transfer above typical off-the-shelf pastes
- High cohesion resists pump-out, dry-out, and bleeding across repeated thermal cycles
- Electrically non-conductive and non-capacitive, so accidental contact with board components carries no short-circuit risk
- 8g tube covers multiple applications on CPUs, GPUs, or laptop chips rather than a single use
- Pairs with a dedicated cleaner solution for full removal of old paste before reapplication
Cons
- Paste cannot be manually spread by design, it relies on cooler mounting pressure to distribute evenly
- Dense, highly viscous consistency makes it harder to apply thin, precise lines than looser pastes
- The companion cleaner for removal is sold separately, not bundled with this tube
A performance-optimized formula with high filler content gives this paste a dense, viscous consistency built specifically for maximum heat transfer between a chip and its cooler. High cohesion is engineered into the paste to resist pump-out, dry-out, and bleeding across repeated thermal cycles, which is what typically causes older thermal paste to degrade and temperatures to creep upward over months of use.
- High filler content for efficient heat transfer
- Resists pump-out, dry-out, and bleeding over time
- Formulated for long-lasting, consistent performance
Because the formula favors long-term stability over easy manual spreading, it is designed to be applied and left in place rather than reworked repeatedly by hand.
By design, this paste cannot be manually spread across a chip surface the way looser pastes can. Instead, a small dot or line is placed at the center, and the cooler's own mounting pressure distributes it evenly outward when it is installed, forming a thin bond line without trapping air bubbles underneath.
- Apply a dot or thin line at the center of the chip
- Cooler mounting pressure spreads the paste on contact
- Low adhesion avoids trapped air bubbles under the cooler
Because manual spreading is not the intended method, following the dot-or-line application rather than trying to smooth it out with a card or spatula gives the most even coverage.
The paste is electrically non-conductive and non-capacitive, meaning accidental contact with surrounding board components during application carries no risk of a short circuit or electrical discharge. That makes it safe to use across CPUs, GPUs, laptops, and gaming consoles alike, without needing extra masking or protective steps around nearby components.
- Electrically non-conductive and non-capacitive formula
- Safe for use on CPUs, GPUs, laptops, and consoles
- Compatible with a dedicated cleaner solution for old paste removal, sold separately
Removing old paste thoroughly before reapplying matters for getting the full benefit of this paste's heat transfer, which is where a dedicated cleaner solution comes in as a companion step.
Pros
- 45 g tube covers dozens of CPU and GPU remounts, enough for a repair bench rather than one build
- Metal-free carbon microparticle formula measured at 3.8 x 10^13 ohm-cm volume resistivity, so a slip onto socket pins will not short anything
- Specified for continuous use from -50 to 150 degrees C, covering sub-ambient loops and hot laptop heat spreaders
- 31,600 Poise consistency spreads under mount pressure alone, so no manual smearing step is required
Cons
- This pack ships without a spatula, so you supply an applicator or rely on the mount-pressure method
- No cleaning wipes in the box, meaning isopropyl alcohol and a lint-free cloth have to be sourced separately
- Grey is the only colour offered, and squeeze-out shows plainly on a dark heat spreader until it is wiped away
The compound is built from carbon microparticles rather than metal oxides or liquid metal. Those particles fill the microscopic pits across a CPU heat spreader and a cooler base, which is where trapped air would otherwise sit and block heat flow.
- Density 2.50 g per cubic centimetre
- Volume resistivity 3.8 x 10^13 ohm-cm, electrically non-conductive
- Continuous use band of -50 to 150 degrees C
The non-conductive part is the practical safety story. Liquid metal compounds can bridge surface-mount components or corrode an aluminium cooler base, and either mistake can end a build. A carbon-based paste that lands on a motherboard is a cleanup job, not a dead board. That makes it a sensible choice for first-time builders and for anyone remounting a cooler in a cramped case where the tube may slip.
Consistency is measured at 31,600 Poise, which is thick enough to hold a bead shape but soft enough to flow when the cooler is torqued down. That means you do not need to spread it manually with a card, and doing so tends to trap air pockets rather than remove them.
- Clean both surfaces with isopropyl alcohol and a lint-free cloth first
- Place a single central bead sized to the heat spreader
- Tighten the cooler in a diagonal cross pattern, a little at a time
For a large heat spreader such as Threadripper or a bare GPU die, a five-point or thin-line pattern gives more even coverage than one central dot. Let mounting pressure do the work in every case, and resist the urge to lift the cooler to check, since that ruins the seal.
At 45 g, this is the workshop-sized tube rather than the single-application syringe most coolers include. A typical desktop CPU mount uses well under a gram, so one tube stretches across many rebuilds, GPU repastes and laptop teardowns.
- 45 g net, shipped in a 4.72 by 4.72 by 0.79 inch carton
- Grey compound, no dye options
- Authenticity check on the packaging to confirm a genuine unit
If you only ever plan to build one PC, this quantity is far more than the job needs and part of it will sit in a drawer. It earns its place with people who service machines regularly, run several systems at home, or swap coolers often while tuning. Keep the cap sealed and store it away from heat so the carrier does not separate over time.

Pros
- 4g syringe includes bundled MX-Cleaner for surface prep before application
- High cohesion formula resists pump-out and dry-out across repeated thermal cycles
- Electrically non-conductive and non-capacitive, safe near CPU sockets and surrounding components
- Compact 4.13 x 0.47 x 0.77 inch syringe fits in a small tool drawer or PC-building kit
Cons
- The dense, highly viscous formula cannot be spread manually by design, so an even bead relies on cooler mounting pressure rather than manual spreading
- 4g syringe size covers roughly one to a handful of applications depending on CPU size, not a bulk supply for repeated rebuilds
- No stated shelf life or expiration guidance is included in the listed features
This is a high-viscosity thermal compound built for CPUs and GPUs that need consistent heat transfer between the chip and the cooler's base plate.
- High filler content formula for exceptional heat transfer
- Electrically non-conductive and non-capacitive for safe use around exposed contacts
- High cohesion resists pump-out, dry-out and bleeding through repeated heat cycles
- Syringe size: 4g, with dimensions of 4.13 x 0.47 x 0.77 inches
Because the paste resists pump-out over time, it's built for setups that see regular thermal cycling, such as gaming or rendering rigs that heat up and cool down repeatedly. The non-conductive formula also means an accidental drip near the socket won't cause a short.
Application differs from thinner pastes: this compound is designed to spread only under the pressure of the cooler being mounted, not by manual spreading with a card or finger.
- Apply a small dot or line at the center of the CPU or GPU die
- Cooler mounting pressure spreads the paste into an even, thin bond line
- Included MX-Cleaner removes old paste and residue before reapplication
- Low adhesion helps avoid trapped air bubbles under the cooler
Because it isn't meant to be spread by hand, first-time users accustomed to manual spreading should apply a smaller amount than usual and let the cooler's clamping pressure do the spreading work, checking coverage on the first removal if unsure.
This compound is rated safe for use across a range of electronics, not just desktop CPUs, since it carries no electrical conductivity risk.
- Safe for CPUs, GPUs, laptops and gaming consoles
- No risk of short circuits or electrical discharge if applied near contacts
- Works with any standard air or liquid cooler mounting system
- MX-Cleaner doubles as prep for reapplying paste on any of these device types
Because the syringe holds 4g, it suits a handful of individual builds or reapplications rather than a shop doing dozens of rebuilds, where a larger syringe size would go further per job.
Pros
- Thermal conductivity of 14.2 W/mK, among the higher figures for a paste rather than a liquid metal compound
- Built to withstand a -250C to +350C temperature range, so it stays usable under liquid nitrogen extreme overclocking sessions
- Zero electrical conductivity (0 pS/m) removes the short-circuit risk that liquid metal compounds carry near exposed pins
- Includes 12 cleaning wipes (6 wet, 6 dry) to degrease the old paste before reapplication, no separate solvent purchase needed
- Non-curing formula stays workable over time instead of hardening, so reapplication does not require chiseling off a dried layer
Cons
- 2g syringe is a small volume, likely only enough for a handful of CPU/GPU applications before running out
- Thin bead application takes more care than a pre-cut thermal pad, since it is easy to overapply on GPU die-sized contact areas
- No pre-applied thermal pad convenience, applying paste with the included syringe and applicator takes extra prep steps
Kryonaut Extreme carries a 14.2 W/mK thermal conductivity figure, with a viscosity of 130-180 Pas and a specific weight of 3.76 g/cm3, numbers that put it toward the higher end of paste-based thermal compounds rather than liquid metal alternatives. Electrical conductivity sits at 0 pS/m, meaning it will not short a circuit if a small amount spreads onto surrounding contacts, unlike liquid metal pastes that carry that risk near exposed pins.
The compound is built to remain stable across a -250C to +350C range, covering everything from sub-zero liquid nitrogen overclocking sessions to sustained high loads under air or water cooling. Nano-aluminum oxide particles in the formula are sized to fill microscopic surface irregularities on a CPU or GPU die, which is what the manufacturer credits for the improved heat transfer over standard silicone-based pastes.
The 2g syringe ships with a dedicated applicator for spreading a thin, even line across the die before mounting a cooler. The formula is non-curing, meaning it stays soft rather than hardening over months of use, so reapplying paste later does not require scraping off a dried layer first. It works across air, water, and even liquid nitrogen cooling setups, and across CPU, GPU, and console hardware including the PS3, PS4, PS5, and Xbox 360, One, Series S, and Series X.
Included with the syringe are 12 cleaning wipes, split evenly between 6 wet and 6 dry, meant to degrease the old paste and any residue off the contact surface before applying a fresh layer. This removes the need to buy a separate isopropyl alcohol kit for prep work, though the 2g tube itself is a small volume best planned for a handful of applications rather than repeated whole-system use.
The package includes a 2g syringe of thermal paste, a specially designed applicator for spreading it evenly, and 12 cleaning wipes (6 wet and 6 dry) for surface prep. That combination covers a full paste-swap job start to finish without needing to source cleaning solvent or an application tool separately.
Because the paste ships in a small syringe rather than a bulk tube, it suits a single build or a small number of upgrade sessions rather than a shop doing repeated builds, where a 9ml bulk size would go further. The wide device compatibility list, spanning desktop CPUs and GPUs to gaming console coolers, makes it a reasonable pick for anyone reapplying paste on a console alongside a PC rather than buying separate compounds for each.

What Makes a Thermal Paste Kit Worth Buying
Not all compounds are created equal, and the “kit” part matters as much as the paste itself. Before you add something to your cart, it helps to understand what separates a genuinely useful kit from a mediocre one.
Thermal Conductivity and Viscosity
Thermal conductivity, measured in W/mK, tells you how efficiently a paste moves heat away from your chip, but a slightly higher number on the box rarely translates into a dramatic real-world difference. Viscosity matters just as much: paste that’s too thick is hard to spread evenly, while paste that’s too runny can migrate out from under the heatsink over time. Look for a compound that balances the two, especially if you don’t plan on repasting often.
What’s Included: Spatulas, Wipes, and Applicators
A true kit should save you a trip to the drawer for isopropyl alcohol and a lint-free cloth. The strongest thermal paste kit picks bundle a spatula for even spreading, cleaning wipes to strip off old compound, and sometimes a syringe-style applicator that makes dosing foolproof. If you’re new to repasting, these extras are worth paying a little more for.
Best Thermal Paste Kit Picks for Every Build
Your ideal pick depends on what you’re cooling and how far you plan to push it. Here’s how the 10 options in this roundup stack up, broken down by the situations each one fits best.
Best Overall: A Proven All-Rounder
For most desktop builds, you want a compound with a long track record rather than an unproven newcomer. The ARCTIC MX-4 has become something of a default recommendation among PC builders thanks to its consistent performance and a non-conductive, non-capacitive formula that won’t damage your board if a little paste squeezes out. If you’d rather have a spatula included so you’re not hunting for a spare card to spread it with, the ARCTIC MX-4 with Spatula is essentially the same compound in a more complete package. Either way, it’s a safe choice if you’re weighing options for the best CPU thermal paste on a first build.
Best Budget Pick Under $10
Not everyone repasting a PC needs a 45-gram tube. The HY880 Thermal Paste Kit ships ten single-use packets, which is handy if you’re maintaining several machines, a small office’s computers, or a couple of game consoles for family members. At under $10 for the whole set, it’s a practical pick if you’re specifically comparing the best thermal paste under $10.
Best for Overclocking and Extreme Cooling
Push your CPU or GPU past stock clocks and every degree starts to matter. The Thermal Grizzly Kryonaut Extreme is built for that scenario, with a formula designed to hold up under sustained high temperatures and the extra thermal cycling that comes with frequent tuning. It also ships with twelve cleaning wipes, so you can reapply it several times while you dial in your settings. If overclocking is the whole point of your build, it’s worth comparing this against other picks built for the best thermal paste for overclocking.
Best for Large Builds or Multiple Systems
Building or maintaining more than one PC changes the math, since a small 2-gram syringe won’t go far. The ARCTIC MX-4 45g Tube gives you enough compound for dozens of applications, which makes sense for system builders, repair shops, or anyone who doesn’t want to reorder every few months. It’s the same trusted formula as the smaller tubes, just sized for volume.
Best Pad Alternative for GPUs and SSDs
Paste isn’t always the right tool for the job. For memory chips, VRMs, and some GPU cooling plates with uneven contact points, a solid pad can make more sense than liquid paste. The Thermal Grizzly Minus Pad Advance is electrically non-conductive and cuts easily to size, which is handy if you’re rounding out a best GPU thermal paste setup with pads for the memory modules while using liquid paste on the core.
How to Apply Thermal Paste the Right Way
Buying a good compound only gets you halfway there. Application technique affects your temperatures just as much as the paste itself, so it’s worth getting right once you’ve got the tube open.
Choosing the Right Amount
More paste is not better. A pea-sized dot in the center of the CPU is usually enough for most desktop chips, since pressure from the cooler mount spreads it into an even layer as you tighten it down. Too much paste can squeeze out the sides, and on some boards that mess is more annoying to clean up than it is genuinely harmful.
Spread Method vs Dot Method
You’ll see builders argue over whether to pre-spread paste with a spatula or let the cooler do the work with a simple dot or line. For large cooling plates, especially on GPUs, a thin manual spread with a plastic spatula helps you avoid air pockets in the corners. For most CPUs, the dot method is simpler and just as effective, so don’t overthink it if you’re repasting for the first time.
Common Mistakes to Avoid When Buying Thermal Paste
A handful of small missteps account for most of the bad experiences people have with thermal paste. Watch for these before you check out.
- Ignoring electrical conductivity: Some high-performance pastes contain metal particles and can short a board if they spread onto surrounding components. If you’re not fully confident in your application skills, stick with a non-conductive formula.
- Buying based on the W/mK number alone: A paste that lists a higher figure on the box doesn’t always beat a well-reviewed competitor in real-world use. Application quality usually matters more than the spec sheet.
- Skipping the cleanup step: Applying fresh paste over old, dried compound traps air and hurts contact. A kit with alcohol wipes included makes this step painless.
- Overbuying on volume: A 45-gram tube is great for a repair shop, but overkill, and a waste of money, if you’re only repasting one PC every couple of years.
- Forgetting cure time: Some compounds need a few thermal cycles before they hit peak performance, so don’t judge a paste on day-one temperatures alone.
Conductive vs Non-Conductive Thermal Compounds
Most thermal pastes on the market, including every pick in this roundup, are electrically non-conductive and non-capacitive, meaning a small amount of overflow onto your motherboard won’t cause a short. Liquid metal compounds are the exception: they conduct electricity, demand far more careful application, and aren’t compatible with bare aluminum coolers. Unless you’re an experienced overclocker chasing the last couple of degrees, a standard non-conductive paste like the picks above gets you nearly the same results with a much lower risk of an expensive mistake.
Frequently Asked Questions
How often should I replace thermal paste?
Most pastes last two to five years before they dry out and lose effectiveness. If you notice rising idle or load temperatures over time with no other changes, that’s a good sign a repaste is due.
Is a more expensive thermal paste always better?
Not necessarily. Many budget-friendly compounds perform within a degree or two of premium options in independent testing. Price often reflects extras like included wipes or a bigger tube rather than a dramatic performance jump.
Can I use CPU thermal paste on a GPU?
Yes, in most cases. The same non-conductive paste works fine on both, though some GPUs benefit from thermal pads on the memory chips alongside paste on the core.
How much thermal paste should I use?
A pea-sized dot in the center of the chip is enough for the vast majority of CPUs and GPUs. Spreading a thin, even layer by hand works better for larger cooling plates.
Do thermal paste kits expire before I even open them?
Unopened syringes typically stay usable for a couple of years when stored at room temperature, though it’s worth checking the packaging for a specific date if you’re buying for a stockpile rather than immediate use.
Whichever kit you land on, the biggest factor in your results will still be a clean application and a properly seated cooler. Spend the extra few dollars on a version that includes wipes and a spatula if this is your first time repasting, and check the current price on Amazon before you check out to make sure you’re getting the size that actually matches your build.
