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

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.

Installed on my Pi 4. Piece of cake to install. Looks cool. Works well. No fan noise issues. Recommended. Will be trying overclocking next, which is why I got this in the first place.

the fan is awesome for cooling the raspi4 when overclocked.

I can highly recommend this ice tower cooler. Im not sure what the stock RGB fan would do or how loud it would be but with a Noctua 40mm fan this Pi 4 8gb is cool as a cucumber! 2147ghz overclock with 700 on the GPU, using an unrealistic stress test only hit 53.5c whereas before with a 2ghz OC and a normal aluminum heatsink with this same fan hit 73c (thermal throttle limit is 80c). Nice improvement for sure and super quiet! This is the Noctua I used: Noctua NF-A4x10 5V, Premium Quiet Fan, 3-Pin, 5V Version (40x10mm, Brown).

I am very happy with this case. The cooling tower keeps my Raspberry Pi very cool. The installation instructions were very complete and simple to follow. I particularly like the Oled display which displays the IP address, CPU load, temperature in Celsius, memory usage and disk usage. The built-in LEDs provide a nice colorful touch. The Oled stats can be programmed to run in the background and and load when the Pi boots up. It does not interfere with any other sketch you are running. All in all this is a very impressive unit.

Before Raspberry fixed there OS to run cooler, this was a very good way to get good cooling performance for your Raspberry PI 4. Fan moves a good amount of air and isnt terribly loud. Fan blades arent sharp so you dont have to worried about little hands getting hurt around this fan. Fan rotates colors : red, green, blue, and purple. There is no control or on/off for the lighting.

Dropped my temps from 71C @ 1.5ghz to 40C @ 2ghz. Probably has more to give, but Im happily running a vanilla minecraft server for my house/friends 24/7 inside a 3d printed case from thingiverse: thing:4249203.

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 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.

I use this in a GOES receiver system. It has definitely helped to reduce the CPU temp. Cheers!
