Re: GTX 480 fan is NOT LOUD! What's up with these reviewers?
I found that the default auto fan speed ramping was unacceptable, it seemed to wait too long to speed up the fan at which point it was playing catch-up.
I was running at 75% fixed but found that using Afterburner and setting up linear fan speed ramping works great.
I'm still running 75C after the temp levels out using Kombustor, the fan still speeds up to 75% but is much quieter when I'm not running a 3D app.
I set the bottom threshhold at 50% fan speed which is practically inaudible.
