Can we put a Heatsink on the Raspberry Pi?

Question

how bout RAM Heatsinks, separate item, is it possible, although have not seen one, but is it small enough to fit? viable? since im torrenting 24/7 (well not really 24/7)

Answer 1

You can put a heatsink on top of the CPU, but as you can see in the picture below, the CPU isn't the hottest part of the board.

The network chip is the hottest part of the RPi. The site where I borrowed this image sells casings that include a heat sink. If you want to use separate heat sinks, you only need a good way to fix them properly on top of the chips (at least for the time is takes adhesive thermal paste to dry).

I guess the 'sandwich' method the referenced website uses for the casing is a very good option, you got your heatsink and a casing in one.

Answer 2

I'm not affiliated with the provider of this in any way apart from being a customer. I've bought two sets of these (Amazon, ModMyPi, Farnell equivalent (not identical model)) for two Pis and they work pretty well. Pretty easy to fix into place with provided thermal tape (although you need to cut it to size yourself).

The set includes 3 heatsinks for the three areas highlighted above.

Answer 3

There are many heatsink "kits" available on eBay for ~$5. They usually contain:

• A heatsink for the main chip (the RAM and SoC underneath it)
• A heatsink for the USB Ethernet Chip (usually the hottest part)
• A heatsink for the Voltage regulator
• 3 heat conductive adhesive pads that make for an easy way to secure the heatsinks on whilst still allowing heat to transfer through.
