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

the fan is awesome for cooling the raspi4 when overclocked.

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.

The heatsink is really good. The fan is optional and not of the best quality but that was as expected and I had already ordered a replacement fan from Noctua. Tested transcoding a full movie on a overclocked Rpi4 and is was stable, averaged around 45ºC.

I have a small pile of raspberry PI computers. I didn’t need to actively cool any of them until the Raspberry Pi 4 came out.

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.

So I have a 4gb model raspberry pi 4 that I want to run some emulators on. I overclocked it to 2ghz core speed and 700mhz video clock speed. This little thing runs very hot though, and will throttle down at 85c. I installed this, pushed a Dreamcast emulator to run Marvel vs Capcom 2, and it never went above 38c, mostly at 37 (I am running a monitor on my main PC to test).

I own two of these. One for Pi3 and Pi4.

awesome i can overclock my pi to 2.2ghz

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.

Easy to assemble and looks great. Only difficult part of assembly is that the wires for the fan barely reach the GPIO pins - much easier with a 4 extension added on. Deducted one star for this.
