“Excellent fan for the Raspberry Pi 4 really drops the temp of your Pi when operating, so quiet, I love the Pi range because it is silent and this fan really complements this ethos.”
“Very easy and quick to assemble and install, even for the non-technical user. No extra tools required for assembly. Works perfectly, with almost zero noise when running. Only minor quibble: if you follow the instructions for the software exactly, it will be installed off of the user's home directory -- should probably add a step to move it into a more suitable location for services/daemons after download.”
“Really simple to install the hardware. Without any software, it simply spins all the time. Very quiet with a casing, not too loud with the casing off. Really easy to follow the software install instructions if you want the LED, auto on/off capabilities. Definitely worth the price and has kept my Pi CPU much cooler.”
