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

Cooling tubes not evenly crimped but apart from that good

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.

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.

Easy

Ok so I watched eta primes video on these hence how I found it but wow I have my pi4 overclocked to 2ghz and ran a stress test for over an hour with this cooler on it and it reached a max temp of 52 degrees Celsius with a base running temp between 30-32 ambient room temp is 75 for the tests so color me impressed and a happy customer

Keeps it under 30° constantly, i have never ever seen it go above 29°. Which made my RPi4 work much faster more consistently (i did overclock to 2000mghz and maxed the GPU and set the voltage to 6)

Got it for my Pi 4 B, fits great and very functional. Stress testing for 10 min at 2.1Ghz and it didnt go over 40 degrees C. That is very impressive.

I purchased this over the Seeed one because it has a bottom plate. That seemed like a good idea to prevent shorts. Installation was easy. Everything fit correctly on a Raspberry Pi 4. The fan is quiet. The heatsink has uneven crimping; this makes it slightly lopsided (3-4mm). This is purely a cosmetic issue. Obviously, they dont QC these units.

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.

This is an excellent cooler and very aesthetically pleasing with the color LEDs of the fan. It consistently keeps my RPi4 (with light to moderate workload) at 29 deg.C, which is fantastic.
