Review on 🔥 Geekworm 12mm Aluminum Alloy Heatsink (C235) with 30mm Cooling Fan Support – Compatible with Raspberry Pi Compute Module 4 CM4 Motherboard by Tim Bunker

Worst of all I find the screws: Both the heads and the nuts are too thick to fit between the cm4 and the I/O board and they are short, to fit through the I/O board into the racks below. Thermal tape is a joke and doesn't sit flat on the chips so make sure you don't over tighten and crack the board. I could drill holes for the screws to go through and fit into the I/O board standoffs, but overall: not worth it.
