“The fan fits well and appears to be good quality. It's very annoying with a high pitched whine that is standard for such small fans. I quickly set the temperature so the fan now only runs when the temp goes above 60°C.”
“Fits in the case as advertised, is easy to install, and runs quietly. With the built-in fan control settings in the Raspberry pi OS, the fan rarely comes on for long.”
“Way to noisy sadly. Can hear it two rooms away. Sounds like those mosquitoes repellers you plug into the mains. Had to remove it as i could hear it in my room and it was also driving the kids nuts.”
