[solved]thermal paste to get heat sink on cpu?

Mon Jun 18, 2018 8:40 pm

Can I put thermal paste on the cpu to get a heat sink on the cpu? Thanks.

What model of Raspberry do you have and why do you think you need a heatsink?

Dougie, because some Pi models get hot enough to throttle by merely opening a webpage and some of us hate tanked performance on an already limited system.

Yes, you can put any compound of thermal paste on your Pi. Be careful not to get it on other components as it is generally conductive.
Also note that the Pi has nothing to hold a heatsink in place, you may need to design a mounting system.

A heatsink on a Zero is a waste of effort because it's next to impossible to get it running hot. A heatsink on a 3B+ may not be needed as the termal conduction of the CPU package and circuit board are an order of magnitude better than earlier models.

Which is why I mentioned "some models".

I fully agree a heatsink on a Pi0 is pointless due to the POP package.

Thanks.
What model of Raspberry do you have
It was a general question about all soc computers.
If you can place thermal paste on the cpu and not destroy it.
