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

Pretty silent, keeps the raspberry temp below 35° in standby, , amazing cooler

Construction of the cooler is great, comes with all mounting hardware and a nice acrylic base.

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 dont want LED lights, I read someone elses 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 cant install the top, it does not matter because it stays super cool (I also didnt need the included base acrylic plate). Ive overclocked my Pi to 2300 with over_voltage set to 11 and it still does not go above 45°. Very recommended, dont pay attention to people that dont know what they are doing.

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

Im only giving this four stars because the instructions for assembly are hot garbage. How ever the unit is keeping my Pi4 icy cool.

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.

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.

I have 2 of these now the second one I just got Feb 2021 came with a second non led fan that did not come with the first one, its nice to have a spare! I have not overclocked yet but these keep the temp below 38c.`1

Temperatures are definitely low, but through empirical testing, a quite small copper heatsink with a fan aimed at it produced lower temperatures in the same ambient environment. I suspect the heat-pipe in this probably isnt of great quality so even though the fan and the fins are excellent, there isnt great heat transfer to them.

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.
