A noisy fan inside a AC Ryan Media Player caused Gerrit van Donk to use the PWM Fan Controller Chip from the PWM Fan Controller Project. This will allow the fan to remain off when the unit is cool inside and only turn on when the system generates some heat. There is a hard drive inside so I would assume this will be the main source of heat but they remain cool under infrequent use and take a while to warm up even under constant use.

“I just cut some wires, grabbed some of the (bulky) connectors I had lying around, soldered them in between and ductaped everything together .”
