Thermal compound, grease, heat sink paste

[xtian]

Need some general purpose thermal grease for transistors, voltage regulators, and the occasional computational engine. What's good, but in small quantities?

Top of Amazon's brain is something like: https://www.amazon.com/Arctic-Silver.../dp/B000OGX5AM

Arctic Silver makes several products. I am not sure how something that is 99% silver can be non-conductive electrically.


ANy electronic supplier you use, like Mouser or Digikey will have silicone thermal heatsink grease. Thermal compound, thermal grease, various similar names for it. Heat sink compound. I use GC brand, but that is because that is what my local electronics parts store carries. Mouser sells Chemtronics. Jameco sells GC:

heat grease | Jameco Electronics


I used "heat grease" as my search term.
Digi sells Chemtronics and MG.

Even Radio Shack used to carry it, maybe still does. If you have a local electronics parts store near you, they likely have it.

Also MCM Electronics, even Fry's.... Heat sink compound. The white stuff.

I am not sure how something that is 99% silver can be non-conductive electrically.

The trick there is that they state that whatever amount of silver in there is 99.9% pure.
But I do agree, I don't want anything conductive whatsoever in heatsink paste, no matter how little there is of it.

The last time I bought some it was from Radio Shack. A .25 oz tube for $2.00. Part #276-1372. Silicone and zinc oxide.

g1, right again, I did not read carefully. It is made from 99.9% pure silver, it isn't itself 99% silver.
