Making temp sensing fan always on...

From what I've seen, no. You need to physically short the leads of the thermistor. Just connect a wire between the two leads of the thermistor. -- Paul

i believe you just cut the thermister off and join the wires.
but i could be wrong.

I thought about that, but I ended up thinking it wouldn't work to short them. If you do that, you're effectively connecting the pos. and neg. wires together. This would short the fan, as electricity always takes the path of least resistance. Since they are in parallel with the normal power leaes, couldn't I just eliminate the thermistor circuit, making it like a normal fan?

I can not imagine a circuit where the sensor is mounted parallel.
What type of fan are you using?

Are you sure it's not wired in series? My understanding is that thermistors work by varying their resistance based on their temp. As they get hotter the resistance drops allowing more current to get to the fan which in turn lets it spin faster.

Ahh, you're right. The neg wires are soldered together (obviously), but the pos. wires for the power and thermistor are separate. So would it be a good idea to just connect them? Its a galaxy fan that hits 50ish cfm @ full speed.

Connect the 2 legs of the thermistor together and enjoy.
