Review on GeeekPi Raspberry Pi 4 Case with ICE Tower Cooler - CPU Cooling Fan, Raspberry Pi 4 Case with Fan, Heatsink & Case for Raspberry Pi 4 Model B by Ray Sheptock

The cooler itself is excellent no complaints. But the reason for 4 stars instead of 5 is because of the acrylic layers that serve as the casing for your Pi. Firstly it is quite difficult to assemble and when you tighten the top 4 screws they tend to tilt which eventually causes one of the corners of the top layer to break. The cooler is excellent, I tested it up to 2147MHz. I use a software controlled switch to turn the fan on and off, so the fan should last quite a while. instead of staying 24/7. PS: To turn the fan on and off automatically, I use an extra small circuit board made by YouTuber Jeremy S. Cook.
