Review on GeeekPi Raspberry Low Profile Cooling Heatsink Computer Components by Jason Tinnen

I chose the downdraft cooler for the dual heatpipes and airflow around all components of the board. With such energy-intensive components, any heat sink with heat pipes is sufficient. Installation: easy. The cooler comes with all mounting hardware (plus extra standoffs, nuts and bolts), a nice little acrylic stand and some thermal pads to interface between the CPU and the cold plate. (I went with an Arctic MX-4 I had lying around.) You probably don't need to worry about the correct mounting pressure, just hand tighten everything according to the diagrams in the manual, or maybe use nut pliers. The included fan is a simple 40mm 5V fan which is really great for cooling anything. There are two jumpers on the fan that connect directly to 5V and GND on the Pi's GPIO headers. (You can also change 5V to 3V3 if you want a quieter/darker fan.) The fan makes a faint whistle, but it's not noticeable unless you're in a quiet room with the fan within a few meters. from you without headphones. At least it's quiet enough that I won't shell out another $15 to swap it for the Noctua. for now. Performance: I was able to easily get a Raspberry Pi 4 core up to 2147MHz and 750MHz graphics, although the graphics could probably be even higher. I ran at around 32°C and maxed out at 45°C CPU under prolonged load (25°C ambient), even when overclocked to >600MHz. At $20, that's a fairly significant fraction of the total cost of installing a Raspberry Pi, but a good cooler is essentially the only way to improve processor performance. This product might be a bit of an overstatement, but hey, it gets the job done and looks pretty impressive thanks to TWO heat pipes and a miniature set of fins.
