Best Thermal Paste for Intel: 10 Picks for 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 single 3.5g tube covers a range of application counts depending on the CPU socket size, since larger sockets need more paste per spread.

• Roughly 20 applications on smaller sockets such as LGA1200
• About 15 applications on AM4 or LGA1700 sockets
• As few as 3 applications on large TR4 Threadripper sockets

No pre-spreading is needed before installing a heatsink, since the compound is designed to spread under mounting pressure on its own. For anyone building or repasting several smaller-socket systems, one tube covers multiple builds, while a single large Threadripper repaste can use a meaningful share of the tube in one application.

This compound is designed for both air and liquid cooling setups across a wide range of hardware, from desktop CPUs to consoles.

• Compatible with AMD Ryzen and Intel Core CPUs
• Works with AMD Radeon and Nvidia GeForce GPUs
• Also suited to PS4, PS5, Xbox consoles, and laptop repasting

Because it is not electrically conductive and does not corrode metal, it is safe to use regardless of whether the cooler base is copper or aluminum, nickel-plated or bare. This broad compatibility makes a single tube useful for repasting several different devices in a household rather than needing a different compound for each platform.

Once applied, the compound is rated for up to 5 years of usage on a CPU before a repaste is generally recommended.

• Up to 5 years of recommended usage time once applied
• Up to 3 years of recommended storage time unopened
• Cleans off easily with a dry tissue, no solvent required for removal

Because the unopened storage window is shorter than the applied usage window, a tube bought well ahead of a planned build may already be past its ideal freshness by the time it gets used. For anyone keeping a tube on hand for future repastes, checking the age against the 3-year storage guidance helps confirm the paste is still in its intended condition before applying it to a build.

The compound is built from carbon microparticles that settle into the microscopic pits across a processor heatspreader and a cooler base, displacing the air that would otherwise insulate the joint. Air is the enemy in that gap, and filling it is exactly what drops core temperatures.

• Continuous use range of -50 to 150 degrees Celsius covers stock and overclocked loads
• Density of 2.50 g per cubic centimetre and viscosity of 31,600 poise
• No cure or burn-in period, so readings are stable from the first boot

Expect a meaningful gap against a dried factory pad and a much smaller one against other quality compounds. The larger wins usually come from mounting pressure and flat contact, so seat the cooler evenly before blaming the paste.

The 8 gram syringe is a generous quantity, enough for roughly ten to fifteen desktop processor applications depending on die size, which suits anyone building several machines or repasting laptops over a few years.

• A pea-sized blob in the centre works for most square heatspreaders; the cooler spreads it under pressure
• Lower the cooler straight down rather than sliding it, since sliding is how air pockets form
• Clean old compound off with isopropyl alcohol and a lint-free cloth first

The consistency is deliberately middling: thin enough to spread under normal mounting pressure, thick enough that it will not run off a vertical graphics die. Store the syringe capped and upright, since a warm cupboard lets the carrier settle out over years.

Unlike liquid metal or metal-oxide compounds, this paste is metal-free and electrically non-conductive. A smear that escapes onto socket pins, surface-mount components or a graphics card board will not create a short, which removes the single biggest risk facing a first-time repaste.

• Safe on processors, graphics dies, laptop chips, VRM heatsinks and console silicon
• No corrosion risk to aluminium or copper cooler bases, unlike liquid metal on aluminium
• An authenticity check lets you verify a genuine unit against counterfeits

Because it does not conduct, it is also the sensible choice for pasting a chip you cannot easily replace, such as a soldered laptop processor or a games console where a slip would be terminal.

This SW Edition tube holds 3.5g of thermal compound, enough for roughly 3 to 20 individual applications depending on the size of the CPU or GPU die being covered.

• Around 3 applications on a large TR4 Threadripper socket
• Roughly 15 applications on AM4 or LGA1700 sockets
• Up to 20 applications on the smaller LGA1200 socket

The compound is rated for up to 5 years of continuous use once applied, with a recommended unopened storage life of up to 3 years, so it suits both immediate builds and near-term future upgrades.

NT-H1 works across both air and liquid cooling setups, covering the current range of desktop CPUs and GPUs as well as several consoles.

• Supports AMD Ryzen and Intel Core CPUs alongside AMD Radeon and Nvidia GeForce GPUs
• Also compatible with PS4, PS5, Xbox consoles and laptop coolers where repasting is possible
• The formula is electrically non-conductive and non-corroding, reducing risk if a small amount contacts nearby pins or contacts during application

Because it works the same way regardless of socket type, the same tube can move between a desktop CPU repaste and a GPU repaste without needing a different product.

The SW Edition bundles a spatula for manual spreading along with three NA-CW1 cleaning wipes, covering both application and pre-clean steps in one box.

• The spatula suits users who prefer a manually spread, even layer over the standard dot or line method
• Cleaning wipes handle residue from a previous application, so no separate solvent is required before repasting
• Non-corroding formula means leftover residue won't damage contacts even if cleanup is delayed

Because reapplication typically happens every few years rather than constantly, this bundle is built as a complete one-stop kit for a full repaste rather than for repeated frequent swaps.

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.

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.

This compound is built around nano-aluminium and zinc oxide carried in a non-curing base. The filler occupies the microscopic pits in a heat spreader and cooler cold plate, replacing trapped air with a far better conductor.

• Stays stable at a sustained 80 C without hardening or cracking
• Non-curing, so a cooler can be lifted later without prying against set material
• Not electrically conductive, so minor overspill onto the substrate is not an instant short

Real temperature results depend as much on mounting pressure, cooler flatness and case airflow as on the compound itself, which is why a single conductivity figure never tells the whole story. Expect a meaningful drop against dried factory material, and a smaller one against a fresh mainstream compound.

The 1 gram syringe ships with a flat spatula, which suits both the centre-dot method on a heat spreader and thin manual spreading on a bare die.

• Strip the old compound with isopropyl alcohol and a lint-free cloth until both faces are dry and residue-free
• Bring the syringe up to room temperature first; cold material is stiff and tears rather than flows
• Spread slowly, since pushing hard drags the compound off the surface instead of levelling it

On consoles the spatula matters more, because PS4, PS5 and Xbox processors sit as bare dies where an uneven blob will not spread under clamping pressure alone. Reseal the syringe and store it in the coated original packaging, which is what supports the three-year shelf claim.

This is a compound aimed at people chasing the last few degrees rather than simply getting a machine running again.

• Desktop processors and graphics cards under sustained overclocked load
• Console repastes where factory material has dried after years of service
• Laptop and small-form-factor rebuilds where cooler headroom is already tight

One gram is a working amount, not a lifetime supply: a standard desktop heat spreader takes a modest dot, while a large graphics die consumes considerably more. Larger syringe sizes exist for anyone maintaining several machines. Because it never cures, it is also a sensible pick for testers who reseat coolers often, since teardown does not mean fighting hardened material off a die.

The compound is a zinc oxide formulation supplied in a 3 gram syringe with a stencil and a spreader. Zinc oxide matters for two reasons: it is electrically non-conductive, so a smear that escapes onto socket pins or surface components will not cause a short, and it stays chemically stable over years in place.

• Low viscosity, so it flows into the fine machining marks on a cooler base
• No volatile compounds, so it resists drying out, cracking or pumping away from the die
• 3 grams covers roughly a dozen mainstream CPU dies, fewer on large GPU packages

The stencil is the genuinely useful extra. It sets both the pattern and the thickness, which is exactly where most first attempts go wrong by applying far too much.

Strip the old compound off first with a lint-free cloth and isopropyl alcohol on both the chip lid and the cooler base. Neither is supplied here, so have them ready before you start. Both faces need to be dry and residue-free before the new layer goes on.

• Lay the stencil over the heat spreader and fill it, or place a pea-sized blob at the centre
• Lower the cooler straight down and tighten the screws in a diagonal cross pattern
• Avoid spreading by hand, which works air pockets into the layer

Do not overtighten one corner, because uneven mounting pressure causes worse temperatures than any compound choice ever will. Once mounted, run a load test and watch the numbers settle across the first few heat cycles.

Replacing an old, dried-out layer on a machine several years into service usually produces the biggest change, often several degrees under sustained load. Swapping from a fresh mainstream compound to this one yields a much smaller difference, since the paste is only one link in the chain.

• Cooler mounting pressure and contact flatness matter more than compound choice
• Case airflow sets a ceiling that no paste can lower
• Liquid metal and high-end carbon compounds still lead by a few degrees on hot chips

Where this formulation earns its place is stability. It will not dry out, crack or need redoing on a yearly cycle, so a machine you build now should hold its thermal behaviour for years without the cooler having to come off again.
