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

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

i really had no idea what to expect with this fan, but i am extremely pleased. i installed it and powered up the Pi for a while. i measured the temperature, and the chips were something like 6C over room temp. that is just amazing. the fan is quiet, and moves enough air to keep everything really cool. the colored light show doesnt hurt either. whenever i have the space, i will use one of these on top of a Pi. well worth the money.

This thing cooled my Pi4 down 40-45 degrees cooler than the fan that came with CanaKit case. It allowed me to overclock the pi and get a little more performance. I will be installing these for future pi projects.

I bought this to help with the thermal throttling i was experiencing with my Raspberry Pi 4. Really helps keeps the temp of the cpu below 40C. The LEDs change colors as its running which is neat but I would rather be able to control them.

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.

This restricts or pretty much prevents use with any enclosure, but it works. I plugged mine into the 3.3 v and it is inaudible. Still I see no high temperatures or thermal throttling. I ran sysbench with 8 threads fully occupying the four cores--the chip temperature only went up to 55c. I do wish you could turn off the lights though.

Update: Seller agreed to send me a new fan. New fan is quiet as a mouse. Happy customer.

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 can highly recommend this ice tower cooler. Im not sure what the stock RGB fan would do or how loud it would be but with a Noctua 40mm fan this Pi 4 8gb is cool as a cucumber! 2147ghz overclock with 700 on the GPU, using an unrealistic stress test only hit 53.5c whereas before with a 2ghz OC and a normal aluminum heatsink with this same fan hit 73c (thermal throttle limit is 80c). Nice improvement for sure and super quiet! This is the Noctua I used: Noctua NF-A4x10 5V, Premium Quiet Fan, 3-Pin, 5V Version (40x10mm, Brown).

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!
