GeeekPi Raspberry Pi Cooling Fan, Raspberry Pi ICE Tower Cooler, RGB Cooling Fan with Raspberry Pi Heatsink for Raspberry Pi 4 Model B & Raspberry Pi 3B+ & Raspberry Pi 3 Model B

Stock CPU clock, running stress tests can’t even bring the CPU above 50c; meaning the fan won’t ever turn on.. awesome

I bought this to help with the thermal throttling i was experiencing with my Raspberry Pi 4. Really helps keeps the temp of the cpu below 40C. The LEDs change colors as its running which is neat but I would rather be able to control them.

This fan has decreased the average temp of my pi 3 B+ by 34%. I mainly use my pi as a DNS sinkhole with the pihole software. Before I installed the fan the pi was around 126 Fahrenheit, with the fan installed It’s down to 83 Fahrenheit.

the fan is awesome for cooling the raspi4 when overclocked.

My Pi machines (4) are mounted on C45 (35mm) DIN rails (no cases) using C45 circuit board adapters. This requires that the configuration must be assembled bottom (C45) to top (cooler). The TO220 heat sink needed to be cut down a bit and mounted to the RAM with 3M thermal tape (thicker than the provided thermal pads) to accommodate the difference in height. The configuration booted up ... first time, no debugging.

Update: Seller agreed to send me a new fan. New fan is quiet as a mouse. Happy customer.

Actually works well at maintaining a cool temperature. The fan is whisper quiet too.

Used it with a 3d print of a “desktop” computer. Looks really great. I don’t run my pi to hard, but it’s always on, and it’s kept it 10-15 degrees cooler than the “passive” system I had before

Mounts up quick and easy. Disappointed it only will cool the CPU the other chips are much shorter and the cooling plate doesnt cover any of other chips. I also had to remove the fan and rotate 90° to be able to power the fan. As the cooler came packaged it was a good inch to short.

This little thing is pretty nice. It does a great job of cooling the processor. The flaw with the design is that it really needs to be turned 90 degrees. The cooling tubes stick out over the graphics chip making it impossible to put any cooling on it as well. Overall a great product, but I am a little disappointed in the design.
