“spot on, so good at passive cooling that with these 4 little sinks you no longer need a fan for your raspberry pi 4, not even when overclocking inside a case!”
“Easy to fix - Sizing of one not quite exact to the IC but sure it works fine. Also bought a case fan but reverted to heat sinks as the noise was too much.”
“Just the right size and with a very sticky backing. I used thin nosed pliers to get them into place. Within a few seconds they are very firmly attached, so you only have one chance to position them correctly. I put them on a spare Pi so haven't actually checked the temperature decrease yet.”
