Review on 🖥️ GeekPi Raspberry Pi 4 Fan and Low-Profile CPU Cooler with RGB Cooling Fan and Heatsink - Compatible with Raspberry Pi 4 Model B, Raspberry Pi 3B+, and Raspberry Pi 3 Model B (Silver) by Daniel Mandal

I ran cpuburn directly on a Pi 4 Model B 8GB for 15 minutes with the CPU overclocked to 2147MHz and the GPU to 700MHz and the highest temp the I saw was 48C. I used the Grizzly Kryonaut Thermal Thermal Grease instead of the included thermal pads, which probably helped drop a few degrees, but overall this stuff kills when you're building an emulation system and getting the best possible performance with high reliability. Two thumbs up, highly recommended. UPDATE: I saw that another reviewer has a photo of the case for this item that he purchased on Etsy from an Esoteric Avenue seller. I should have had one. And I have one and it's amazing. Times are exactly the same except now I have protection. If you're looking for a case for this low profile ice tower cooler, I highly recommend getting one of his!
