Best Overall: Rmal Grizzly High Thermal Conductivity Thermal Paste

Buy on Amazon

The rmal grizzly high thermal conductivity thermal paste is capable of outshining several other paste featured in this list in overall features. One of the best things about the Kryonaut paste is that it is very easy to apply. It comes with a 3 page folding instruction pamphlet, a card with a verification code, and a spatula for spreading. It is easy to work with, using the included spreader. It is also very durable and can last for a long time without needing to be reapplied.

This is more of an enthusiast's thermal paste. The product is Thermally conductive to allow heat transfer, but non-conductive with voltage, meaning if you apply a little too much to the IHS and it spreads too much, it won't short your system. There is a big leap by 10 deg from their best supplement, but the scales are basically based on time over temp change. The paste is also very durable and can last for a long time without needing to be reapplied.

• Built a water cooled amd ryzen threadripper 3960x machine, works fantastic
• 42 degrees celsius, no gaming usage
• New and hot release

Best For motherboard: Noctua High Thermal Conductivity Thermal Paste

Buy on Amazon

This thermal paste is great for cpus WITH an ihs however if you use this on bare die (PS4/5, XBOX, GPU, Delidded CPU) don't expect it to do good or last. It is an enthusiast-grade paste for the highest demands. The new compound is more much more malleable and applies very well with the pea sized dot of thermal paste applied. The wipes work well cleaning off the old paste of the aio and cpu.

This product is easy to use and similar to most thermal pastes. It is transfering heat to the case.

• Easy to use and you will like it
• Max temperatures are well, well below any throttling (45°c) at stock
• Three packs is just about sufficient to remove both cpu/gpu and cooler residue
• Included alcohol wipes were nice for removing previous thermal paste

Best For Cpu Cooler: Arctic Silver High Thermal Conductivity Thermal Paste

Buy on Amazon

Arctic Silver offers a variety of paste for personal choice and yet maintaining quality in all the variants. This thermal compound is the best you can get and does amazing things when applied by someone who knows what they are doing or something who follow the directions on the arctic silvers website. Even if it's one degree, or keeps the temp down an extra minute or so on a failing part, it works very, very well. The density polysynthetic silver thermal compound enhances the compound's performance and long. The locking bar is still down, so the CPU is secured in there firmly.

This is an excellent heat-sink compound. The compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long. The hypodermic style applicator makes application easy without any messes or messes. It is a staple for enthusiast builders.

• Works great on cpu's, gpu's, ram and mosfet's
• Good brand reputation

Best For Xbox One X: Arctic High Thermal Conductivity Thermal Paste

Buy on Amazon

Not everyone likes to purchase paste for their daily purpose, but the arctic high thermal conductivity thermal paste would be an anomoly. This thermal paste is good because artic makes it. It comes with its improved composition, the arctic mx-6 has a measurably lower thermal resistance than the mx-. It is easy to apply and lower the temperature of cpu by 20 degrees celsius. It is also free of liquid metal components, which can often lead to discoloration, abrasion or corrosion damage to the radiator bottom. It comes with bbq sauce in those gift sets, to glaze meat but w/ barely any sauce left.

It gets quite hot even while using PBO and undervolting. The Steam Deck also has been noticeably quieter vs Kryonaut. It comes with free spreader tools to make installing this easier.

• Keeps 7600x under control and tastes good
• Slightly higher fan rpms by no more than 10% to avoid noise increase
• One of the new comers and featured product

Best For console: Corsair High Thermal Conductivity Thermal Paste

Buy on Amazon

If you often find yourself confused about appropriate and satisfactory paste, corsair high thermal conductivity thermal paste is your end point. This kit includes a 5 gram syringe, easily enough thermal paste for 5 to 10 "standard sized CPU" applications. It allows it to easily fill microscopic abrasions and channels for peak thermal transfer. It comes with a stencil you apply to your CPU cooler. It is great for new builds or refurbishing/upgrading current hardware.

Ultra-low thermal impedance lowers cpu temperatures vs common thermal paste. This product does it's intended function and is easy to apply. It is made with actual passion. It is pretty easy to use tbh, works well and looks cool.

• Excellent thermal paste for optimal cooling
• Works great and perfect amount for a couple small jobs
• Runs nice and cool, not messy

Best For electronic: Moneyqiu High Thermal Conductivity Thermal Paste

Buy on Amazon
