So here is the situation - I have 5 ASIC miners to which I've fitted high powered fans to keep them cool. This works perfectly, however these are quite noisy fans and could like make some kind of temperature profile for them so if a temp of 40c it increases the fan speed appropriately. But I don't have a PC available in vicinity, but I could have a Linux (mac mini) located near them. That aside is there an "independent" fan controller with temp sensors that anyone is aware of?
