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

This little thing is pretty nice. It does a great job of cooling the processor. The flaw with the design is that it really needs to be turned 90 degrees. The cooling tubes stick out over the graphics chip making it impossible to put any cooling on it as well. Overall a great product, but I am a little disappointed in the design.

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.

Stock CPU clock, running stress tests can’t even bring the CPU above 50c; meaning the fan won’t ever turn on.. awesome

This took my Pi4b overclocked at 1750 from 53C to 24C. I added the extra fan on the other 5v connector and put it on the other side of the heatsink. I am also using thermal paste fyi.

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.

this thing is insane!!! overclocked to 2.4 ghz on the cpu and 800mhz on the gpu and it never went over 45℃ while maxing out all 4 cores for 20 minuets. I highly recommend this product. its worth every penny!

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.

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.

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.

For 15 dollars I thought I would get some cheap every 1/100tg of a penny matters product. Instead I got a extremely well built cooler that came with an extra everything, it came with the base stuff you see in the ad but also a Magnetic screw driver to build it which made it super easy, extra Fan yes an extra fan.
