Summary: I'm sure this is a good product from the many reviews I've read. But for some reason it doesn't work for me. The fan, which works fine when connected to the motherboard, simply doesn't turn at all using this controller. It isn't the specific controller either as I purchased two and neither work. I'm going to hang on to them in case I need them on a new computer build I"m working on. Perhaps they will work with different fans.
Summary: This thing is pretty junky. I wish I had gotten something a bit better for my stir-plate for my beer brewing hobby. The thing seems to really have just 2 speeds, pretty slow, and too fast. The knob sticks haft way through turning.
Nice part and hackable too... To make it even more useful.

Summary: Nice part, nicely hackable.. I wanted a fan to come on with a 5 deg difference in controler temp to ambient temp and turn on more as the temp gets higher and try to maintain that difference to perhaps 80 deg F controller temp. This will be a part of an accurate and comprehensive metering panel for my AMD 6100 using DS18B20's and an Arduino Micro... And a nice project for an old retired engineer to keep busy.. Robert K.
