I purchased Corsairs TXM850 power supply, it is powering my PC, but the fan is not running on it. Does the fan always run, or does it just turn on and off as it gets too hot?
Low Noise with Zero RPM Fan Mode
The fan doesn’t even spin under light to medium loads – that is, a lot of the time that you use your PC. And when you’re pushing it hard, the Enthusiast Series TX-M varies its fan speed in response to temperature, so the 140mm double ball bearing fan spins only as fast as it needs to. The result is exceptionally low noise levels.
that was taken from the TX650M but i would assume they are all the same.
So what you are saying is...don't freak if the fan blades are not moving at all if the PC has been turned on recently/isn't hot yet...:D I guess I can send in that MIR after all.
