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 can overclock without worrying about it overheating. A+

Cooling tubes not evenly crimped but apart from that good

Best fan I’ve plug into a Raspberry Pi 4!!! Keeps it cool all day and not loud like other fans.

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

Cant believe I bought a cooler with RGB lights but here it is. Like all on my computers, if I am now actually sitting in front of it, then its running some distributed-processing app like the old seti. I use 100% of available processors 85% of the time. The color is supposed to indicate temperature and its all blue and green. Just checked a temperature sensor in the Pi and its reading 47 C. Sounds pretty good to me.

this thing is insane!!! overclocked to 2.4 ghz on the cpu and 800mhz on the gpu and it never went over 45℃ while maxing out all 4 cores for 20 minuets. I highly recommend this product. its worth every penny!

Dropped my temps from 71C @ 1.5ghz to 40C @ 2ghz. Probably has more to give, but Im happily running a vanilla minecraft server for my house/friends 24/7 inside a 3d printed case from thingiverse: thing:4249203.

Keeps it under 30° constantly, i have never ever seen it go above 29°. Which made my RPi4 work much faster more consistently (i did overclock to 2000mghz and maxed the GPU and set the voltage to 6)

Came with an extra fan that was black just in case you dont like the colorful one. Included all of the tools you need to attach this to a raspberry pi including some thermal interface material. Really solid build quality and the instructions were written well. Great for the price, would buy again.

With this beast of a cooler, I was able to manage a super stable CPU overclock at 2.3GHz and GPU overclock at 750MHz on my Raspberry Pi 4 (8 GB model). Temps idles around 30-33° C and never get above 50° even after full load on all cores (using stress-ng) for more than 15 minutes, at which point temps seem to stabilize there.
