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

If this isnt the coolest option for the PI, I dont know what is. i big tricky to install if handling small nuts and bolts is a problem. . . . . like it is for me with hand tremors.

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 is actually my second one - I liked the first one so much that when I bought a second Raspberry PI 4, there was no debate as to which cooler I was going to use. Easy to mount, quiet, and works like a charm. Great build quality - it just works, as opposed others I tried. (Pimoroni Fan Shim, Im looking at you!) My idle temps are around 27 degrees C, and the Pi stays well within safe limits even when overclocked.

It seems to work really well, keeps things nice and cool. Was a little wonky to install, not hard but just took me longer than id like.

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.

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...

was able to easily overclock my pi and keep the temp low

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.

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

Used it with a 3d print of a “desktop” computer. Looks really great. I don’t run my pi to hard, but it’s always on, and it’s kept it 10-15 degrees cooler than the “passive” system I had before
