“Very straightforward to install. With the third wire to control the fan speed, it means the fan only operates when required and keeps the whole unit very quiet most of the time.”
“Came with included heatsink, seems to do a good job of keeping the Pi cool even under longer heavy workloads.
Make sure to set up in raspi-config, otherwise it'll stay on constantly!”
“Whilst the unit itself self controls heat by reducing power and performance as it reaches its upper threshold, the fan adds active cooling. It also enables fan control to activate the fan on my when reaching the threshold so the fan does not constantly run. Very cheap, very simple and very useful!”
