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

Love this RGB fan for my Pi4. They generally run hot but the thing has been cool as a cucumber since I got this. Definitely recommend.

Got it for my Pi 4 B, fits great and very functional. Stress testing for 10 min at 2.1Ghz and it didnt go over 40 degrees C. That is very impressive.

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.

This little fan is really nice, makes your rasp pi look almost like a tiny desktop computer. I used thermal paste instead of the adhesive thing it came with. You can get some nice overclocking done with this on top, and keep your processor nice and chilly so it doesnt throttle.

I have a Raspberry Pi 4 - 8 Gig that I use for my desktop computer. I had this RPi encased in a metal heat sink case. This worked well until I overclocked it. Then the normal running temperature jumped from ~55 to ~67 degC. The GeeekPi Raspberry Pi Cooling Fan, Raspberry Pi ICE Tower Cooler fixed that problem. It now hovers 46-48 degC in normal operation. I am running the 3 volt power option. This is very quiet. I never notice the fan. That said I do have a slight hearing problem. But, as the saying goes, Works for me..

Highly recommend this cooler for your raspberry PI 4 I have not seen my Pi go higher in temp than 31 degrees on full load

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

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.

My Rasberry Pi4 stayed at 37-38 C when playing with tons of games. I have included pictures for those buying this with a case since no one has posted any. Hope this helps. I will always buy this combo whenever I have new Pi4 build.
