Thanx for the reply, but I tried that and it worked until I booted my PC today in the morning and it did it again! Just when the password screen pops up for desktop loading, the fan starts spinning really fast, do not know whats the speed an im not on the desktop screen yet, but it is really loud which tells me it mite be even at 100%! And as soon as I log in, it drops down to 24%, the default starting speed from CCC. And eventho Afterburner is running it doesnt really load the 'fan curve' and I have to manually do that...Any more suggestions??
