GeeekPi ICE Tower Cooler for Raspberry Pi, RGB Cooling Fan with Aluminum Heatsink for Raspberry Pi 4B/3B+/3B (Black)

All OK

I have a Noctua NH-D15S chromax.black in my desktop, so I bought this just because it looks cool and thought it would be a fun compliment. I was halfway thinking this was just a gimmick and wouldn't actually have a real benefit.I installed this on a new Raspberry Pi 4B 4GB. To take the install over the top, I sanded off most of the paint on the base with 400 grit sandpaper and then polished it with 1500 grit to get a nice smooth surface for mating to the CPU. Rather than using the supplied thermal adhesive I used some NT-H1 thermal compound that I had laying around. Attempting to follow the pictures in the installation guide I assembled the mounts backwards the first time, but it was easy to correct.Following the install I thought it would be a good idea to run some thermal stress tests. The case that I ordered is still in transit so for now it is sitting on my desk in open air, ambient temperature is ~24C. I used Stressberry to run 3 tests, Fan Unplugged, Fan connected to 3.3V, Fan connected to 5V. Because I was so excited to install the heatsink I didn't run any stress tests without it installed.Fan unplugged: Idle 33C, Stress 44C3.3V Fan: Idle 30C, Stress 39C5V Fan: Idle 29C, Stress 36CAt these temperatures there was obviously no throttling. These were short 15 minute tests so I may not have reached stability. Once I get the Pi installed in the case I'll run longer tests to determine how I want to run it long term. I bought a Noctura 40mm fan that I'll be testing as well, just to increase the cool factor a little bit more.If you want your Pi to run cool or just look cool this is the cooler to get. Is it overkill? Yes. Am I happy with my purchase? Yes.

It was able to lower temps on a rpi4b from 83c during a stress test to 37c.You will need longer screws if you want to install a Noctua fan.The original shipment arrived with some damage to the fins but the seller offered a full refund.

Moved from official Pi3+ case. Dropped average temperature by 10 degrees F.And SUPER quiet.

First cooler came in missing all the mounting parts (spacers, nuts and screws) and appeared to be a return that wasn’t checked before sending out again. It was replaced quickly and the replacement had everything needed to set up and install.

Previously was using the Vilros passive cooling case with a Sandisk Extreme 32gb card, stock CPU settings. Liked the case as it came in contact with the CPU, ram, ethernet and usb controllers. Looks good too.For my use, got so hot the pi kept slowing down and becoming unresponsive. Too bad.Added this cooler, same conditions but added my own heatsinks to the other chips as this cooler only contacts the CPU.Rock solid at 1.5ghz. Not a single issue. Never overclocked a pi before so gave it a try.Ramped up to 2ghz. Temp never got over 40°C!Run this command via command line to monitor temperature:watch -n 1 vcgencmd measure_tempEven when stressed with near 100% CPU load at a full 2ghz, never skipped for 12 hours and only touched 44°C for a short time. Was performing large file transfers (large and small files, 5 bay raid usb 3.0, four simultaneous transfers and random speedtests via chromium) to test.System is running full Raspbian and OMV (wired ethernet, 5-bay usb 3.0 enclosure). Very usable as a workstation (and background server) for light office use, not video editing or heavy tasks. That is what a PC is for.Fan is a quiet hum and barely noticed it running. Nice touch on the color changing LEDs.Would highly recommend the cooler and would like to know if anyone has tried Retropi while overclocked? Would be interesting.

My base temps with OpenELEC installed was 50C. Installed on skin and it idled at around 52C. After I installed this heatsink my idle temps dropped to 33C. Streaming 4k movies my temperature has never passed 35C. I have not overclocked my 8GB Raspberry Pi 4. There really is no reason to overclock it for OpenELEC.I brought this small heat sink kit for the copper heatsink. https://www.amazon.com/gp/product/B079FV2RH3/I brought this small tube of Grizzly Kryonaut Thermal Paste. https://www.amazon.com/gp/product/B011F7W3LU/I also had other heat sinks from ordering my Raspberry Pi.First I scraped the paint off the bottom of the heatsink with some sandpaper. It takes like 30 seconds to get to the copper. I then placed the 0.5mm copper heat sink on top of the CPU and, spread a thin layer of the thermal paste on top of it. I matched up the other heatsinks to place them wherever they would fit. Everything has a heatsink on it. I had to slide one heatsink slightly off center for it to work with the install.I also ordered a case off of Etsy made for the Ice Tower. I did see the plans to print it yourself with a 3d printer are on thingiverse. I do have a 3d printer but it is temporarily in the attic. So I went ahead and brought one.

Used some thermal paste to attach it, definitely works better than a passive heat sync, looks way cooler, and fits nicely in my case (with just enough room for my SSD to squeeze on top)
