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

Overclocked to pi 4 cpu to 2ghz and 750mhz on the GPU. No matter what I throw on this thing I cant get the thing to even hit 100° f. I see some people saying its difficult to put together and its absolutely not if you have more than three brain cells in your head. Will be ordering two more very soon.

was able to easily overclock my pi and keep the temp low

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.

Pretty silent, keeps the raspberry temp below 35° in standby, , amazing cooler

I have two Rasberry Pi 3B (2015).

Before Raspberry fixed there OS to run cooler, this was a very good way to get good cooling performance for your Raspberry PI 4. Fan moves a good amount of air and isnt terribly loud. Fan blades arent sharp so you dont have to worried about little hands getting hurt around this fan. Fan rotates colors : red, green, blue, and purple. There is no control or on/off for the lighting.

Cooling tubes not evenly crimped but apart from that good

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.

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).

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