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

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.

Muy bueno se recomienda

Cooling tubes not evenly crimped but apart from that good

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!

This fan keeps my RPi-4 at about 93 - 95F which is about 15 - 20 degrees cooler without. The install was fairly straightforward.

I use this in a GOES receiver system. It has definitely helped to reduce the CPU temp. Cheers!

This took my Pi4b overclocked at 1750 from 53C to 24C. I added the extra fan on the other 5v connector and put it on the other side of the heatsink. I am also using thermal paste fyi.

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 slapped this on my raspberry Pi 4 for giggles since it really doesnt need any extra cooling for running octopi. Came with an extra black fan and all you need to do is to remove 4 screws to install it instead of the RGB one. You can run this fan on 3v so its dead silent.

Installed on my Pi 4. Piece of cake to install. Looks cool. Works well. No fan noise issues. Recommended. Will be trying overclocking next, which is why I got this in the first place.
