The Best Thermal Paste for Streaming Setups in 2026

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.

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.

A gram sounds small until you see how little compound a joint actually needs. The layer only has to fill microscopic gaps between two machined surfaces; excess simply squeezes out and adds thermal resistance rather than removing it.

• A standard desktop CPU takes roughly 0.2 to 0.3 grams applied as a central pea
• A large heat spreader on an LGA1700 chip takes a little more, spread thin
• A bare GPU die takes very little, since the contact patch is small
• A console heat spreader is the greediest, closer to half a gram

Plan on three to five processor applications from this tube, or one console service with some to spare. If a rebuild involves multiple cards and thermal pads as well, order accordingly rather than running short halfway through a strip-down.

Preparation matters more than technique. Both mating surfaces must be clean and dry before anything is applied, or old compound will keep the new layer from making full contact.

• Wipe the old compound off with isopropyl alcohol and a lint-free cloth
• Let both surfaces dry fully before starting
• Apply a pea-sized dot at the centre for a square heat spreader
• Use the supplied spatula to spread a thin even film across a wide console spreader
• Seat the cooler straight down and tighten fasteners in a cross pattern

Do not spread by hand on a small CPU. Mounting pressure distributes it more evenly than any manual attempt, and hand spreading tends to trap air. Resist the urge to use more than needed; a thicker layer is worse, not better.

Two properties define how this compound behaves over time. It is electrically non-conductive, and it contains no silicone.

• Non-conductive means an accidental smear onto nearby components will not create a short
• Silicone free means no low molecular weight siloxane gases to creep onto contacts
• It does not harden, so removal later needs no chipping or heat

The quoted thermal resistance of 0.0076 K/W puts it among the stronger non-metallic compounds. It will not match liquid metal on a bare die, but it also will not attack aluminium coolers or risk shorting a board, which is why it remains the sensible default for water blocks and large air towers alike. Expect several years of service before renewal is worth considering.

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.

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.

This is a thick paste built for large contact surfaces, and it rewards a careful method rather than a quick squeeze.

• Clean both the heat spreader and the cold plate with isopropyl alcohol until no oily film remains
• Bring the syringe up to room temperature first, because cold paste drags and tears instead of flowing
• Spread slowly. The supplied applicators let you level a thin, even film rather than relying on mount pressure alone
• A single dot works on a small die, but wide coverage is the whole point of this formula on a large spreader

Because it never cures, a cooler can be lifted and reseated months later without chipping a hardened layer off the die. If you do remount, wipe both faces and apply fresh paste rather than reusing the squeezed-out film.

The formula is tuned for medium and large heat sinks and for water blocks, where the contact area is wide and heat has to travel across the whole plate rather than out of one small central point.

• Desktop processors under air towers, and 240 to 360mm all-in-one liquid blocks
• Graphics card dies during a cooler rebuild or a repaste
• Console heat spreaders on PS4, PS5, Xbox 360, Xbox One and Series X
• MacBook logic boards, where throttling often follows dried factory paste

Being silicone-free and non-curing is the property that matters on hardware you expect to open again. The syringe holds 7.8 g by weight and 3 ml by volume, so one tube covers many mounts across several machines rather than one application and a bin.

Two points deserve attention before the first use.

• The listing headline describes the paste as conductive while the detail text describes it as non-conductive. Treat any spill onto surface-mount components as something to clean off carefully rather than ignore
• No thermal conductivity figure is published, because the maker argues contact pressure, temperature and surface finish change the result too much for one number to mean anything on its own

For storage, keep the syringe in its original coated packaging with the cap fitted. That internal coating exists to stop the plunger and nozzle drying out. Sealed and kept at room temperature, the paste stays usable for at least three years and often longer. If a tube has been open a while, squeeze a small bead onto a tissue first to clear any oil that has settled out.

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.

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.
