There was a utility that had support for several different manufacturers (though not all options available for all boards) that allowed some tweaking whilst in the OS not necessarily available via bios etc. Unfortunately I've lost the url for it. I'm specifically after OS utility for fanspeed adjustment for an A7N8X. Had a search through old posts of mine as I'ed thought I'ed tagged the post about this from 6-9 months ago, but no luck
The first description sound like 8rdavcore, but that only allows you to monitor the fan speed not change them. You could try speedfan, but again I think that can only monitor. What you would really need is a rheobus or an LCD (with GPU's) with mbm5/speedfan plugins
Isn't that an automated system, the fans speed up as power consuption increases. I dont think you cant make changes from within the OS.
Hmm, you're probably right, I've never used an Asus board myself. Speedfan is what I immediately thought of too, but then I remembered something about Q-fan and Asus
q-fan is built into the bios which slows the fan on the cpu down relative to the temperature of the cpu...with the new mobo's (A7N8X-D with recent bios) onwards i believe it allows you to change the speed ratio and the response time, but again that is in the bios...
