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 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.

Not sure what the thickness and sheerness stars are for...warmth - well, it removes that so I didnt give it stars for warmth - we need one for coolness instead. I use a pi4 on bad solar power days when I dont want to run the big 8 core + big nvidia content creator box, and overclock the pi to 2 ghz as well as overclocking its little GPU to make it a decent daily driver. I also got the nvme gumstick adapter for mine and the combo is a winner that draws much less power than a display. I dont need the lights, but hey...

the fan is awesome for cooling the raspi4 when overclocked.

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.

Temperatures are definitely low, but through empirical testing, a quite small copper heatsink with a fan aimed at it produced lower temperatures in the same ambient environment. I suspect the heat-pipe in this probably isnt of great quality so even though the fan and the fins are excellent, there isnt great heat transfer to them.

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.

I had to replace the noisy and annoying fan. It was loud in both sound and sight. I live in a studio apt and it lit up the whole living area.

My rpi was running at about 40-48C and slowing down with the heatsink it came with. I installed this and it keeps it below 37C on the 5v pin. Gets a little hotter on the 3.3v one, but still better than a passive heatsink. This was the key maintaining 1.5ghz on all cores as I’m not seein any throttling now!

Actually works well at maintaining a cool temperature. The fan is whisper quiet too.

Via my 3d printer, I made a special case for my Pi4. Then installed this cooler. Works great for my overclocking of that Pi. Does a great job of keeping that unit cooled. Id recommend this cooling setup.
