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 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 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 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.

Kryonaut is rated to maintain stable thermal transfer without drying out at sustained temperatures up to 80C, which matters for overclocked CPUs and GPUs that run hotter than stock parts over long sessions. The 1-gram syringe delivers enough material for multiple standard-size CPU or GPU die applications.

• Stable performance without drying out up to 80C
• 1-gram syringe covers multiple applications
• Compatible with CPU, GPU, and console cooling systems

Because it holds up under sustained high heat rather than just short bursts, it suits overclocked or workstation-class systems that run near their thermal ceiling for extended periods, not just idle or light-use setups where a stock paste would already be adequate.

The kit ships with a spreading spatula alongside the syringe, plus 6 wet and 6 dry cleaning wipes for degreasing the CPU or GPU surface before application. Preparing the surface properly before applying new paste has a direct effect on contact quality between the die and the cooler.

• Syringe applicator with spreading spatula included
• 6 wet and 6 dry cleaning wipes included
• No separate cleaning solution purchase needed

Manual syringe application takes a steady hand, since applying too much paste around a small CPU or GPU die can squeeze out over the edges once the cooler is mounted, so a light, even layer works better than a thick blob.

This paste is built for overclockers and performance builders working on CPUs, GPUs, and consoles including the PS4, PS5, and Xbox, rather than casual users doing a first-time build with stock cooling. It replaces factory paste that has already dried out or is being upgraded ahead of an overclock.

• Suited to overclocking and repasting CPUs or GPUs
• Compatible with PS4, PS5, and Xbox console coolers
• Best used alongside a cooler upgrade or repaste project

A single 1-gram tube covers several applications but is not sized for a shop repasting dozens of systems, so high-volume use would call for a larger syringe size instead of this one.
