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 silver thermal paste is rated for thermal conductivity above 3.17 W/m-k and thermal resistance below 0.067°C-in2/W, figures that place it ahead of many pastes bundled free with stock coolers. It's rated across a working temperature range of -50°C to 240°C (-58°F to 464°F).

• Thermal conductivity: greater than 3.17 W/m-k
• Thermal resistance: less than 0.067°C-in2/W
• Working range: -50°C to 240°C

The formula is non-electrically-conductive, non-toxic, and non-corrosive, reducing the risk of damage if a small amount spreads beyond the die during application, unlike liquid-metal compounds that require careful masking.

The 20g tube is rated for use across CPU, GPU, heatsinks, LED assemblies, and gaming console chipsets, including PS4 and Xbox hardware. A spatula is included for spreading the paste evenly during application.

• 20g tube volume for multiple applications rather than a single use
• Spatula included for spreading, no separate tool needed
• Suitable for CPU, GPU, LED, and console chipset use

The listing's instructions cover cleaning the old paste off first, applying a fresh layer, spreading it evenly, then reinstalling the cooler, following the same general process most thermal pastes require rather than a shortcut method.

Rated to handle temperatures from -50°C up to 240°C, this paste is built to keep working through both cold startup conditions and sustained high-load heat rather than breaking down at one extreme.

• Wide -50°C to 240°C working range covers most consumer PC and console use cases
• Flame-retardant, non-volatile formula reduces fire risk near heat sources
• Long-term stability claimed for extended use without reapplication

Since the listing doesn't specify a recommended reapplication interval or a pump-out resistance figure, users running sustained high loads (24/7 servers, mining rigs) should still monitor temperatures over time rather than assuming indefinite performance.

Duronaut's formula blends aluminum microparticles with zinc oxide nanoparticles, engineered for efficient heat transfer while minimizing the pump-out effect that causes thermal paste to migrate away from the die over time. The compound is electrically non-conductive, removing the short-circuit risk that liquid metal alternatives carry near exposed pins or contacts.

• Aluminum microparticle and zinc oxide nanoparticle blend for heat transfer
• Minimized pump-out effect for long-term thermal resistance stability
• Electrically non-conductive, safe near exposed contacts

Compared to liquid metal compounds, this formula trades some raw thermal conductivity for a simpler, lower-risk application process.

The 6 gram tube provides enough compound for multiple CPU or GPU applications rather than a single one-time use. A TG Spatula Pro applicator is included for spreading an even layer, and 12 cleaning wipes, split evenly between 6 wet and 6 dry, prep the surface before application and clean up afterward.

• 6 gram tube covers multiple reapplications
• TG Spatula Pro included for even spreading
• 12 cleaning wipes, 6 wet and 6 dry, included

Manual spatula application takes more time and care than pre-applied thermal pads, but gives more control over layer thickness across the die.

Duronaut is marketed for CPU, GPU, PS4, PS5, and Xbox thermal interfaces, positioned specifically for overclocking scenarios where long-term stability under repeated thermal cycling matters. It's engineered to resist hardening over extended periods rather than needing frequent reapplication.

• Compatible with CPU, GPU, PS4, PS5 and Xbox thermal interfaces
• Built for overclocking and sustained high-load thermal cycling
• Resists hardening over extended use periods

Even with its durability focus, extreme overclocking loads over several years will still eventually call for a fresh application, this is a long-interval solution rather than a permanent one.

The compound reaches full thermal performance immediately after mounting, with no burn-in period, so a temperature check taken straight after a build reflects what you will still see months later.

• Clean first. Remove old compound with isopropyl alcohol and a lint-free cloth from both the die or heat spreader and the cooler base.
• Quantity: a pea-sized blob in the centre for a mainstream CPU, or a thin cross for large server-class heat spreaders.
• Let pressure spread it. Mount the cooler evenly, tightening screws diagonally a turn at a time, rather than spreading by hand with a card.

Viscosity is high by design, since that resists pump-out under thermal cycling, but it makes the syringe stiff. Warming it in a pocket or a warm room for ten minutes before use makes dispensing far easier to control.

The formulation is carbon-filler based in a silicone gel carrier, and the maker quotes measurably lower thermal resistance than the MX-4 compound it replaces — around a 20% improvement in their own testing.

• Not electrically conductive and not capacitive, so a smear reaching the substrate or a nearby surface component will not cause a short or a discharge.
• That property matters most on direct-die work: delidded CPUs, bare GPU dies and console processors, where silicon sits surrounded by exposed circuitry.
• No metal particles such as silver or diamond dust are used, which is exactly what keeps it safe to handle around live hardware.

Against liquid metal it gives up several degrees under extreme sustained loads, but liquid metal carries real risks around aluminium and exposed traces. For most builds this is the sensible compromise.

Eight grams is a workshop quantity rather than a single-build quantity. A mainstream desktop CPU takes well under a quarter of a gram per application, so the syringe covers roughly thirty repastes — more if you are frugal, fewer on large heat spreaders or laptop dies with several contact points.

• Typical use case: someone maintaining several machines, repasting a laptop annually, or building systems for friends and family.
• For a single CPU, most of the syringe will sit in a drawer between builds.
• Storage: cap it firmly and keep it at room temperature, since the carrier gradually stiffens once air reaches it.

An authenticity check on the packaging lets you confirm the syringe is genuine, which is a real concern with widely counterfeited thermal compounds.

The published figure is 3.195 W/m-K at 25 C, achieved through a compound that is roughly 60 percent metal oxide. That puts it ahead of plain silicone greases while keeping electrical conductivity negligible, unlike liquid metal compounds that will happily bridge two contacts.

• Stays stable from -22 F to 365 F, so it copes with sustained full-load temperatures and with cold storage between service jobs
• CE and RoHS certified, which matters when the machine being serviced belongs to a client or an employer
• Matched to processors drawing up to 65 W TDP, which covers most office desktops, small servers and integrated chipsets

Above that wattage the compound becomes the weak link in the chain, and a higher conductivity paste is the sensible pick for enthusiast or overclocked silicon.

The 1.5 g tube is sized for maintenance work rather than a single build, holding enough for four to six applications. The resealable syringe cap is the reason it lasts: paste left uncapped skins over and turns gritty long before the tube empties.

• Remove old compound with isopropyl alcohol and a lint-free cloth, then let both mating surfaces dry before applying anything
• Dispense a small central dot and let cooler clamping pressure spread it, tightening mounting screws in a diagonal pattern
• Wipe any overspill from the edge of the heat spreader before powering on, since this compound carries metal oxide

Re-pasting is the fastest fix for a workstation that has started throttling after several years, and one tube covers a whole rack of office machines during a refresh cycle.

This is aimed at technicians and IT staff keeping fleets of desktops running, not at overclockers chasing the last two degrees. The tube volume, resealable applicator and 65 W TDP guidance all point the same way: routine servicing of mainstream machines.

• Office desktops and workstations where the factory paste has dried and fan noise has crept up
• Integrated chipsets and small servers running heat sinks with modest thermal loads
• Anyone maintaining several machines who wants one tube to cover multiple visits rather than a single-use sachet

For a high-wattage gaming processor under an all-in-one cooler, or for direct-die work on a bare graphics chip, a carbon-based compound with higher conductivity and zero metal content is the better tool for the job.
