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

Using for my overclocked RPi 4B media server.

Want to run a RaspberryPi 4b 8GB at turbo locked 2.3Ghz all-core clock, with the VideoCore VPU/GPU running at 750Mhz, 24/7 reliably? The IceTower will get it done, with headroom to spare. At the afore mentioned clocks, under full CPU and GPU torture-test loads, my temps never exceed 56 degrees. Under normal heavy loads (building a project, for example) it never even breaks 40 degrees, and idles at 30.

This fan has decreased the average temp of my pi 3 B+ by 34%. I mainly use my pi as a DNS sinkhole with the pihole software. Before I installed the fan the pi was around 126 Fahrenheit, with the fan installed It’s down to 83 Fahrenheit.

This thing really works. My cpu temp barely ever budges even under heavy loads. I also like the LEDs. I suppose its kinda silly for a simple little RPi but it makes me smile and it does what it says it does.

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

I bought this back on October 20th, 2021 and as of today December 16, 2021 it is already louder than my PC. I wanted to use these as a cooler for my many octoprint setups. The mounting bracket is also loose on the board and does not actually apply pressure to the CPU. Ive tried bending the legs to fit. Otherwise, its just loud and makes no noticeable difference in the temperature versus without on a raspberry pi v3 B+.

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.

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

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.
