I know the SF2 has a built in temp sensor, and i assume it can plug into the motherboard to report rpms, but can it report the temperature it's sensing along with the rpm? or is there any fan at all that can do this?

Look up a product called a DigitalDoc 5. 8 sensors you can place, can control fans based on sensor readings.
What the "autoadjusting" fans do is NOT to report temp, rathert they use a thing called a thermistor. When a thermistor gets hot it gets LESS resistive, more current flows, fan goes faster. Problem is, fans with heat right at fan means a case that is probably already too hot. DigitalDoc 5 has sensors on leads, lets you put them basically anywhere you want. It has a circuitboard to control fans and a decent sized LCD or LED to display (seen both in various models of DigitalDoc-- one display for each DigitalDoc) its results and gives you a way to sense multiple places at once whiule turning fans on or off or running them slow or fast in single fan or groups depending on how you wire things.

There are no fans that I'm aware of that report the temperature, as there's really no way to do it anyhow. Sure, you could use a pulse generator, replace the rpm signal with a temperature-controlled pulse instead, and then write software to convert that back to a temperature, but then you'd be paying $50 for the fans instead of $5....
yeh that's a bit more than i was looking for. i'm thinking if i just add 10*C or so to my temp it'd be better lol ... right now, double folding, at 43*C which isn't accurate - can't be on stock hsf. room temp is about 22*C

running two instances of f@h, including playing music/messenger/AV/popup killer and whatever other junk is running in the background? with 80% humidity and these temps? everyone keeps telling me it's damn near impossible .... hm ... if i took one of those electronic outdoor temp monitors, that has a sensor on a chord, and set it right on the top of the heatsink, maybe even between the fins a little, would it be anywhere near accurate, or how much off would it be? would be an interesting test...
