Where to buy

The HEATGREASE20 CPU Thermal Paste Compound can be used to improve the effectiveness of a CPU cooler, by thermally bonding the surface of the CPU to the heatsink, which enables the heatsink and fan to work more efficiently to remove harmful heat from the CPU.

This 20g tube of ceramic-based thermal grease is enough for a large number of CPU installations for most home or business computers or any other light application where good thermal bonding between two surfaces is required.

Please see our support section for the Material Safety Data Sheet for HEATGREASE20.


  • Replace old or dried out thermal paste to replenish heat dispersion between a CPU and heatsink
  • System builders who put together many low-end to mainstream systems

It didn't work out. My HP2000 wasn't happy with this compound. It's no use... The laptop dies after a few seconds after showing desktop...

Hello AvaLon, Thank you for taking the time to review our HEATGREASE20 Thermal Compound. We are sorry to hear about the system stability issues and we would like to offer some help. Before applying the thermal compound, was any exiting thermal compound cleaned off of both surface? Any existing compound that is not removed safely using a cleaner like isopropyl alcohol could leave pockets of air which will severely affect the thermal transfer between the component and the heatsink. When applying thermal paste only a small amount is required, approximately the size of a grain of rice. We are always here to help with our free lifetime technical support. Are you able to contact us directly and provide more information on the components that our thermal compound is being used with? If so please contact us as soon as is convenient for you and reference case #332-289415 so we can further assist you. You can also reply here and we will be sure to follow up. Thank You, Customer Support StarTech.com http://www.startech.com/support

Ok for MidRange Build

Heatgrease20 is a good product. I use it for up-to 95watt processors with NO overclocking. Overclocking needs a higher rated paste.
