“Great little heatsink. Easy to fit and keeps my Raspberry Pi 3b cool while it runs pi.hole and pivpn software for me 24/7. I can also confirm that this fits under the official power-over-ethernet hat, sitting just under the fan to increase the effect of active cooling.”
“It fits my Pi 3 perfectly and was very easy to fit with the pre applied heat proof adhesive. Looks great and being matt black it is really good at keeping my Pi cool. It had no sharp edges like some heatsinks I have bought in the past. It looks good and is really good value for money excpet the postage on such a small item could be a lot cheaper.”
