“Cute smol anodised heatsinks for only 2 quid. What's not to like? Only gripe would be, it's a shame they don't do them in black. Also, I'm not an expert on the Pi 4 but I'm not totally sure how necessary ones on the smaller chips are. Can't do any harm though (assuming they don't come loose and rattle around inside the case.... may be a good idea to degrease the top of the ICs before applying?)”
“Very easy to apply- just peel off the thermal tape with a pair of tweezers and use those tweezers to position the heatsink. The size and shape of each make it easy to see what chip they are for.
They get fairly warm on my Raspberry Pi 4b, so are doing a good job.”
