“Great cheap little fan, does an amazing job of cooling the CPU. One minor warning - by default it's on all the time, and while that's great for keeping your Pi supercool, it can be a little noisy depending on where your Pi is living! Use raspi-config to set the fan to only come on when CPU hits 60 degrees and the issue goes away.”
“Was not obvious to me how it installed.
Wiring was clear but physical positioning was not.
Quick youtube search sorted that but a simple pic would have been nice.
Actual fan is noiser than I would expect when at 100% but I know smaller fans can be loud.”
“Easy to fit, little noise in operation. I went into the configuration settings and set it to come on when the CPU reached 60 degrees simple operation to carry out”
