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.

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.

This set contains 3 spatula pieces in different sizes, designed to spread Thermal Grizzly paste evenly across a range of chip surface areas without contaminating the compound by hand. It works with the brand's full paste lineup: Aeronaut, Hydronaut, Kryonaut, and Kryonaut Extreme.

Application surfaces covered include desktop CPU and GPU integrated heat spreaders as well as console chips across PS3, PS4, PS5, Xbox 360, Xbox One and Xbox Series X, along with laptop chips such as those found in MacBooks. The tool itself does not include any thermal paste, so it is meant to be paired with a separately purchased compound.

• 3 spatula sizes in one set
• Compatible with all 4 Thermal Grizzly paste lines
• Works on CPUs, GPUs, and console chips

Correct paste application affects thermal conductivity directly, so an applicator like this is meant to replace uneven finger spreading or a single blob-and-clamp method. Use the largest spatula for bigger heat spreaders such as desktop CPUs, and the smaller sizes for tighter GPU dies or console chip packages.

Apply a small amount of paste to the center of the chip, then use the flat edge of the appropriate spatula to spread a thin, even layer covering the full contact surface without excess buildup at the edges. Clean each spatula between uses to avoid carrying old, dried compound into a fresh application, since dried paste residue can create uneven contact spots under the cooler.

This set suits PC builders and console repair users who already own or are buying a separate tube of thermal paste and want a controlled, mess-free way to apply it rather than relying on finger spreading. It is particularly useful for anyone reapplying paste during a CPU or GPU cooler reseat, or during a console repair to address rising temperatures.

• Good fit for PC builders doing their own paste application
• Useful for console repair and repaste projects
• Not needed if you only ever use pre-applied thermal pads

Since no paste is bundled, pair this set with a Thermal Grizzly compound purchase if you don't already have one on hand before starting a repaste.

ARCTIC MX-4 delivers premium thermal conductivity with a non-conductive formulation that remains safe for direct contact with exposed circuit traces and component leads. The paste stays stable across repeated thermal cycles without pump-out or degradation, maintaining consistent interface performance from first application through years of operation. Tested compatibility with Intel, AMD, and ARM processor packages ensures broad system support.

The non-corroding, metal-oxide formula handles CPU and GPU mounting equally well in both desktop and mobile applications. Unlike traditional thermal pastes that separate into oil and paste components over time, MX-4 maintains homogeneous density and thermal conductivity throughout its service life. Ideal for systems experiencing frequent thermal stress from gaming, rendering, or overclocking activities. The non-curing design means it never hardens, enabling reversal of mounting decisions without scraping or solvent cleanup.

Each 4-gram syringe includes a precision metal spatula for spreading thin, even layers across die surfaces. The included spreader tool prevents fingertip application errors that trap air bubbles and create uneven contact. The low-stress application method prevents damage to delicate silicon dies and solder bumps found on modern processors. A small amount goes far, with most CPU coolers requiring only a rice grain or pea-sized dot in the center of the die.

Clean the spatula with isopropyl alcohol between applications for reuse across multiple systems. The reusable tool quality means you keep it across multiple thermal paste replacements, reducing waste and eliminating the need to purchase additional spreading tools. Application typically takes less than one minute on standard desktop CPUs, making re-mounting straightforward for maintenance tasks.

MX-4 works with Intel and AMD desktop processors, graphics card GPUs, RAM modules, chipset cooling solutions, and mobile processors. The non-conductive formula eliminates risk of shorts if paste contacts component circuitry during application or system operation. Compatible with all mainstream mounting systems from Intel LGA1700 and AMD AM5 current generation down to legacy CPU sockets from previous decades.

Store at room temperature away from excessive heat and direct sunlight to maintain optimal consistency and performance. The sealed syringe maintains usability for many years before opening, with no shelf life concerns under normal storage conditions. Once applied, reapplication is simple and straightforward: gently warm the CPU cooler, remove it cleanly from the die, and apply fresh paste to the die surface before remounting the cooling solution securely.

Kryonaut is rated at 12.5 W/mK thermal conductivity, aimed at demanding builds and overclocked systems that generate more heat than stock cooling setups typically handle. The compound is engineered to stay stable and not dry out at sustained temperatures up to 80 degrees C.

• 12.5 W/mK thermal conductivity figure
• Stable performance without drying up to 80 degrees C
• Nano-aluminum and zinc oxide filler compound

The nano-aluminum and zinc oxide particles are designed to fill microscopic surface irregularities on a CPU or GPU die for more even contact with the cooler.

This set includes 3 applicators, 3 spatulas and 6 CPU cleaning pads, enough tools to clean and repaste more than one component without buying separate accessories. The syringe applicator is built for precise dosing, since too much or too little paste both reduce contact quality.

• 3 x applicator syringes
• 3 x spreading spatulas
• 6 x cleaning pads for surface prep

Application should be slow and deliberate - spreading too quickly can cause the paste to lift off the surface instead of laying flat, which reduces its effectiveness.

With proper storage in its original packaging, Kryonaut remains usable for at least 3 years after opening, and often longer. The syringe should be resealed after each use and kept at room temperature rather than exposed to heat or direct sunlight between applications.

• Usable for 3+ years after opening with proper storage
• Best applied at room temperature for easier spreading
• Surface should be fully clean and grease-free before application

Thermal conductivity figures are not printed on the retail packaging itself, so buyers relying on that number should reference the manufacturer's technical documentation.

Kryonaut is built around a small set of measurable performance specs rather than general claims.

• Rated thermal conductivity of 12.5 W/(m-K) targets demanding processor and graphics card cooling.
• Thermal resistance is listed at 0.0032 K/W.
• Electrical conductivity of 0 pS/m means the compound will not conduct electricity if it spreads beyond the die.

These figures position the paste for overclocked systems and demanding workloads rather than casual, low-heat builds where a standard paste would perform similarly.

Because these figures are independently measurable, they allow direct comparison against other high-performance pastes rather than relying on general marketing claims.

The compound is engineered to stay stable across an unusually wide temperature span.

• Rated temperature range runs from -250C to +350C, covering both extreme cold and high industrial heat.
• The paste is formulated to avoid drying out at sustained temperatures up to 80C.
• Specific weight is listed at 3.7g/cm3, with a viscosity of 120-170 Pas.

This stability profile suits long-term installs where reopening the case to reapply paste is inconvenient, such as sealed small form factor builds.

The combo package is built to make precise application straightforward.

• A 5.5g syringe of paste is included, sized for a handful of individual applications rather than bulk servicing.
• An extra spatula is included alongside the syringe for spreading the paste evenly across a CPU or GPU die.
• The thicker 120-170 Pas viscosity holds its shape during application rather than running off the die immediately.

Because the paste is non-conductive but still messy at this viscosity, working over a clean, static-safe surface helps avoid cleanup around nearby components.
