Review on GeeekPi Raspberry Cooling Cooler Heatsink by Kyle Armstrong

Previously used a passive Vilros cooling shroud with a Sandisk Extreme 32GB card, default processor settings. I liked the case as it interfaced with the processor, RAM, ethernet, and USB controllers. Looks good too. It got so hot for my use that the Pi started to slow down and become unresponsive. Too bad. I added this cooler, same conditions but I added my own heatsinks to other chips as this cooler only contacts the processor. Works stably at a frequency of 1.5 GHz. Not a single problem. I've never overclocked a Pi before, so I gave it a try. Overclocked to 2GHz. The temperature never exceeded 40°C! To monitor the temperature, run this command from the command line: watch -n 1 vcgencmd Measure_tempEven under almost 100% CPU usage at a full 2GHz, never missing for 12 hours and only touching 44C briefly. Large file transfers were run for testing (large and small files, USB 3.0 5-disk raid, four simultaneous transfers, and random speed tests via Chrome). Very handy as a workstation (and background server) for light office use rather than video editing or heavy duty. That's what a PC is for. The fan hums quietly and hardly notices its operation. Nice touch with color changing LEDs. Would highly recommend the cooler and would like to know if anyone has tried retropi when overclocking? It would be interesting.
