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..

This product is amazing! I really cannot understand why so many people review it and say that the instructions are not accurate or not for the right product. If you can follow simple instructions, look at the pictures (to make sense of how to install the parts), you should not have any trouble. It literally took me less than 10 minutes to set this thing up, yes there are things that are questionable, but when you look at the picture in the small installation manual, you realize what it means and can proceed without trouble. I used thermal paste instead of the included pads and my temperature literally does not go above 45°. It is well worth it, very affordable and very quiet (even inside an enclosed arcade cabinet with no other fans). Inside the box you also get a tiny screwdriver, perfect for the job! The extra fan is for those that don't want LED lights, I read someone else's review talking trash about it.. get over it! You do not need to install the extra fan or build other parts with 3D printers or anything like that, the single fan will do the job just fine. I have a CanaKit version of a Raspberry Pi 4b 8GB with their own enclosure and even though I can't install the top, it does not matter because it stays super cool (I also didn't need the included base acrylic plate). I've overclocked my Pi to 2300 with over_voltage set to 11 and it still does not go above 45°. Very recommended, don't pay attention to people that don't know what they are doing.

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!

I have a Pi 4B sitting in a waterproof box outside in the Florida heat, running PiAware, and also feeding to ADSBx and FlightRadar24. Connected to the Pi are also two ADSB receiver dongles. Previously I had it in a basic Canakit enclosure with a small fan. I never had issues with the Pi crashing, but PiAware would constantly nag me about it overheating.I purchased this fan, and as you can see from the screenshot, it’s now running at a happy 39.4c, and I haven’t seen it peak much more than a few degrees over that. While I didn’t need the RGB fan since nobody sees it anyways, the heat sink and fan does the job well, and wasn’t too expensive.Definitely a good buy, and the fan didn’t seem noisy at all when I tested it indoors before bringing it back outside.
