“Very easy to install and get setup. Cheap price and very fast next-day delivery.
I bought this because the fan that came bundled with the linked case is always on and too loud. I wanted to be able to have the fan only turn on when the Pi's temperature was high, and it was very easy to get that working. I ran "sudo raspi-config" and set it in the system menu rather than the GUI menu in the instructions.
I was also pleased to find that this fan is much, much quieter than the bundled fan I was previously using (which was annoyingly loud and high-pitched). I can now barely hear it. Great result.”
“Bought for a Raspberry Pi in the attic connected to an ADS-B aircraft monitor. Its existing low-speed fan which was on all the time worked OK, but the software control fan enables it to operate at full speed during the day when it is hot and shut off at night when it's cooler, to maintain a more consistent temperature.”
