Review on Enhance Your Raspberry Pi 4B Performance: Cooling Fan, RGB Hat, and OLED Display Combo! by Rui Hanson

I had a really hard time getting this fan to work! I'm not new either! I use Gentoo on all my laptops, work computers and all my Raspberry Pis. I've also been writing software for 15 years. I had to change some python code, create some custom ebuilds to compile custom software to make I2C work, and change a bunch of configuration files. If you don't have problems with that then this fan is great, but if you are a beginner I would suggest getting another fan.
