GeeekPiRaspberry Pi Low-profile CPU Cooler, Raspberry Pi Horizontal ICE Tower Cooler, RGB Cooling Fan with Raspberry Pi Heatsink for Raspberry Pi 4 Model B & Raspberry Pi 3B+ & 3B (Silver)

Does the job, very, very, very well. Running a nextcloud on it, never gets above 45

I put together a custom build arcade machine setup, with custom rgb button lighting via a ultimate i/o board, rgb buttons, digital 360 sticks and an rpi4. Had a couple of tiny lags on a few of the larger games, so wanted to get this sorted. Who wants lags, right?Simple install of this little beauty and well, well, well, look at this:Stats - pre installClock speed 1.5ghz53 degrees idle60 degrees in useStats - after installClock speed 2.0ghz (overclocked)29 degrees idle40 degrees in useI'd say that's a winner!So, if arcade retropie or similar is your setup and you want to overclock then hey there, get one of these, brings that bad boy down to an acceptable level of temp!

This is extremely cool. Much like its predecessor, but having less height, this fan is perfect for any Pi (4 in my case). And it is especially good for those who use RetroPie, as I do...Buy it!

I would have given it 5 stars except for the price, £12-£15 would have been more realistic for this cooler. It does a good job of keeping the chip cool, but over priced.

Keeps the CPU nice and cold even at extreme over clocking. Awesome and easy to install.

This is a great little cooler just a smaller version of a pc cooler even with heatpipes. I found I got even better performance if I used a tiny blob of thermal paste instead of a heat pad. max temp of 37c at a 2GHZ overclock on a pi 4 with 620 MHZ on the GPU. And the RGB is quite cool too lol but wont work with corsair icue ;-)

Works really well. Would recommend

Easy to fit and works very well
