Is that even right algoritm? Assume I'm running at very cold room, lets say -10C. Assume idle CPU will hover around 30C with no fan, or hover around 10C with fan running, trip point being 50C. You _could_ leave fan off until 50C, having silent, passively cooled system. What it will do instead is annoyingly pulse fan at 10C.
