“The fan is very, very annoying. The fan has a high-pitched squeal.
Using the GPIO to control the fan helps but still irritating when it does come on.
Also blocks many of the GPIO pins, so you have limited choices which GPIO pins to use (thinking of the UEFI fan choices).”
“Very interesting ideea but unfortunately no speed control, sunt on or off, extremely noisy and if you don’t mind not having the top cover on you could get way better temperatures from the cheapest fan with a bigger heatsink on the internet. Waist of money in my opinion”
