I'm not sure what you mean for your papers, though. If you're planning on doing this for a school project or something, all you need to do for that is to wire in a thermostat in series with a resistor. When the temperature exceeds your preset level, the thermostat trips and bypasses the resistor, which causes the fan to speed up. You could in theory use multiple resistors to create stepping, or even a variable one if you want finer control, but the simplest circuit is one thermostat, one resistor, one fan.

No diagrams. If you really want a wiring diagram, draw it yourself. I've given you everything you need, and if you don't know how to diagram it you shouldn't be doing something like this in the first place.

Good fan there in your link, the only problem is I think the OP was wanting a fan for his CPU. My question would e WHY would you want a fan like that for your CPU? In my OPINION, I would want a fan that runs on its highest setting to keep my CPU the coolest that it can. you NEVER want a fan that might actually stop, because it takes less than a second for todays CPU to start frying with no fan running at all. Your theory is a good idea, but practicality is where I see a potential problem.
