GeeekPi ICE Tower Cooler with RGB Cooling Fan and Heatsink for Raspberry Pi 4B/3B+/3B

Yo this thing keeps raspberry pi ice cold no matter what I do, doesn't even matter if I leave it on for a couple weeks working on a complex tasks, stays perfectly fine!Actually worked on the raspberry pi 5 for me too, I just sort of had to flip the brackets around differently. Highly recommended! I don't like using the fan with the RGB lights myself, but they do look super freaking cool. Since I leave mine on all night usually I just don't want the lights keeping me up..It is so quiet too I never even notice it!One weird thing and it's not the Fan's fault it's totally the pi, but it stays on even when the pi's turned off..

I bought this specifically to overclock my Raspberry Pi 4 so that it could be a decent retrogaming console for my wife. I've been building my own gaming PCs for almost 30 years, so she's very familiar with CPU coolers. When I showed this to her, her reaction was "OMG, it so cute!" But behind the cuteness are some amazing cooling capabilities.The cooling fan wasn't difficult to install. The kit includes everything that you need to secure it to the RP4, including a precision screwdriver and a plastic mounting plate. Once the fan is connected to a 5V (or 3.3V) power source, it starts up as soon as the PR4 is turned on.I installed it as per instructions with one main difference: I used Arctic Silver 5 instead of the stock thermal stickers, which in general are okay but usually inferior. After it was assembled, I decided to stress test it by overclocking my RP4 to CPU at 1.95 GHz, GPU at 600 MHz, and V3D at 750 MHz, and then ran a process to calculate prime numbers on all four cores. With all four overclocked cores running at 100%, CPU temperatures stayed within 27-30°C, even after several minutes, which is amazing.And before anyone asks, the RGB LEDs cannot be controlled; they cycle through different colors. The only connections on the fan are positive and negative power cables. That's it.So if you have any possibility of overclocking an RP4, this is definitely the cooler to get. I already plan on getting another RP4 and even if I don't overclock it (who am I kidding? I definitely will), this fan will be installed with it.

Keeps my raspberry pi 3B+ ice cold. I used to have my pi have severe issues with lagging and freezing due to heat creep. Now it runs smooth under the same heavy computational load. The fan is quiet as well. Wish there was a case to cover it up but I suppose the best is to just 3d print one. I can now run klipper with my Webcam at 30 fps, from lagging and freezing up at 15 fps.

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.I may be wrong, but I believe the Pi firmware will start some light thermal throttling at 60°C and then full on throttling beyond 80° C. With the ICE cooler you will not get anywhere near those thresholds even with the highest possible overclocking settings you can manage on the Pi 4. The bottleneck becomes the Pi 4 itself. Usually at this point any attempt to push the Pi 4 CPU higher results in crashing in the stress-ng benchmark or it refusing to boot. But! Even at extreme settings with high overvolts, temps never got to throttling levels. I’m my testing, crashing was caused by power limits and the physical limits of the CPU.The RGB fan is definitely a flashy touch that may not be for everybody, and it definitely adds to the ridiculousness and adorableness of this miniaturized desktop-class heatsink, the but the kit does come with a black non-RGB fan that you can switch it out with. The kit also includes a few paper-thin thermal pads, but I just ended up using some high-quality thermal paste when mounting the heatsink. Yeah, at that point it really is overkill upon overkill, but hey, go big or go home right?Definitely recommended for those Pi enthusiasts out there!

Cooler works great for my project! I did not use this on a raspberry Pi, I used it to cool an ASIC chip on my Bitaxe, I used a different fan that really pulled the air through this cooler. I’m able to put more voltage to my ASIC chip as this cooler does a great job keeping my ASIC chip cool. I would recommend this cooler.

Very well made and looks great. Perfect for my Raspberry Pi Pico 8 system.

Keeps my Raspberry Pi nice and cool

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.I don't know of a case that is designed to fit the cooler at this point, and not sure I would want one which would hide the color LEDs. However, the plastic baseboard (included) will protect the bottom side of the RPi4 from contact damage.Beware of the instructions in regard to the RPi GPIO pin locations to connect he power and ground leads for the fan. They seem to show the GPIO wrong pins to connect these leads (a photo is included, but no written instructions on the pin locations). You need to consult the official RPi GPIO pinout diagram for the correct 5V power and ground locations. The cooler's instructions say you can also use 3.3v power for a lower fan speed, but honestly I don't think that is necessary, as the fan noise is very low anyway using the full 5V power.
