“Much better than other fans I have had for my other devices - this one is smarter and with simple to follow instructions (included) comes on when required and switches itself off when the Pi is cool enough. Excellent product and price!”
“small & fits pimoroni housing - cut the screws to fit on top of metal heatsink (but soldering or taping might be required to keep it from slipping off the pins.”
“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.”
