Review on GeeekPi Raspberry Low Profile Cooling Heatsink Computer Components by Ken Ayo

Nice cooler, nice RGB lighting and a fan that isn't too annoying. Temperatures not seen by others with PI 4 CPU @ 2147MHz, 1.0441V and 750MHz GPU. Did a few CPU stress tests and the final temperature stabilized at 54C with an ambient temperature of 23C. Replacing the thermal pad for some Arctic MX-4s dropped to around 49C, but the heatsink surface was non-slip but it doesn't look perfectly smooth and that might help too. It's a bit overkill unless you're running something CPU intensive. For comparison I tested the Flirc case with the same settings, it got hot up to 78°C but stayed hot longer due to the passive cooling.
