If anyone is looking for a very simple, temperature-dependent
fan speed control, check this out:

It uses a 10k pot, NTC thermistor, MOSFET and 12v fan. I just built one
using a 40mm Sunon fan for a small SBC enclosure and it works great. All
parts (except the fan) are available from Radio Shack and cost about $7.
