promey on fan controller safety issue

if you put the promey fans on a controller as like i have to be able to get the extra cooling make sure in your boot options that you have the computer set to reboot on power failure.
i was gone today, power went out, came back on and the promey started up without the fans. not sure how long it had run like that but it was pretty hot.
seems to be running fine now though so i hope no damage was done. i wasnt gone long anyways.
