Asus motherboard - control of chassis fan?
I've just upgraded my machine with an Asus M4A78LT-M LE motherboard and an Athlon 250 CPU. These were an upgrade on a barebones system based around an Asus A8R-MX DP motherboard.
The old system used to control fans speeds very well, only upping them when the motherboard or CPU got too hot (the AMD cool 'n quiet thing). For some reason I can't get the new arrangement to do this, I've installed Asus' software (PC Probe II) and it notes that the motherboard temperature is below threshold (33°C or so) but it won't drop the an speed from 2,800rpm. It's therefore very loud.
Is there a way of getting the fan to kick in only when needed, or otherwise slow down? I had assumed this is what PC Probe II was meant to do, is this just a monitoring programme and should I seek to control fan speed elsewhere?
All advice gratefully received.
