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 Samiran Pusarla

Great for cooling Raspberry Pi 4. I preferred it to the higher version mainly because of the potential for more heat pipe contact with two separate 5- Millimetre-heat like pipes going through the CPU block compared to a single pipe in the high version (https://www.amazon.com/GeeekPi-Raspberry-Cooling-Cooler-Heatsink/dp/B07V35SXMC ). Installation: I took a dremel with a buffed bit and buffed the area of the heatsink that touches the processor on the rPi and buffed the top of the rPi processor (probably not necessary but I already had a dremel). I also bent the brackets a bit. to lightly press the heatsink against the processor. I just used the mounting plate and hardware that came with the heatsink. I didn't use the thermal pads that came with it, I used the silicone thermal paste I had (it was Phanteks PH-NDC). Conditions: Ambient around 21°C, powered by Pi's official USB-C power adapter. Temperatures: Working Stock Settings, at 100% CPU load, the temperature stayed below 34°C for 15 minutes when I ran it. (0.15V) processor and ran at 100% load for 20 minutes, the temperature never rose above 44°C. Compared to the standard ratings of 80°C+ without heatsink, and people are satisfied with 60°C+ with fan, I think these temperatures are great! Cons: If I could change anything I would probably replace the fan, the color changing is terrible and the brightness borders on annoying, mine will probably be replaced with a less bright fan at some point in the near future.
