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

I bought this back on October 20th, 2021 and as of today December 16, 2021 it is already louder than my PC. I wanted to use these as a cooler for my many octoprint setups. The mounting bracket is also loose on the board and does not actually apply pressure to the CPU. Ive tried bending the legs to fit. Otherwise, its just loud and makes no noticeable difference in the temperature versus without on a raspberry pi v3 B+.

Temperatures are definitely low, but through empirical testing, a quite small copper heatsink with a fan aimed at it produced lower temperatures in the same ambient environment. I suspect the heat-pipe in this probably isnt of great quality so even though the fan and the fins are excellent, there isnt great heat transfer to them.
