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

This thing really works. My cpu temp barely ever budges even under heavy loads. I also like the LEDs. I suppose its kinda silly for a simple little RPi but it makes me smile and it does what it says it does.

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.

awesome i can overclock my pi to 2.2ghz

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.

Construction of the cooler is great, comes with all mounting hardware and a nice acrylic base.

I am very happy with this case. The cooling tower keeps my Raspberry Pi very cool. The installation instructions were very complete and simple to follow. I particularly like the Oled display which displays the IP address, CPU load, temperature in Celsius, memory usage and disk usage. The built-in LEDs provide a nice colorful touch. The Oled stats can be programmed to run in the background and and load when the Pi boots up. It does not interfere with any other sketch you are running. All in all this is a very impressive unit.

I really like it. Looks great and works well. Probably not the best price on the planet.

Fan works great. Easy to install. Keeps the Pi at a nice stable cool 31°C

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

Highly recommend this cooler for your raspberry PI 4 I have not seen my Pi go higher in temp than 31 degrees on full load
