I have a small issue with my new GTX 570SC and am unsure exactly where the problem lies.
 
I got my new card, and just done a clean installation of Windows.
I did not use anything off the CD that came with it.
I just downloaded the drivers from Nvidias site, and grabbed Precision 2.0.3
 
I enabled Software Auto Fan controller, and set a fan profile I'm comfortable with. And for the most part it works fine,.
 
But sometimes, it just doesn't do anything.
For example, earlier I had installed one of my games and was setting it up.
When I exit out, my GPU was at 88C, and fan speed was at 40% -- Auto.
 
Disabling and re-enabling Auto done nothing. The fan speed was just stuck at 40%.
 
 
I rebooted the system, started Precision and it kicked in again.
 
 
When this happened the first time, I was wondering if it was because I had Precision set to Start w/Windows and Start Minimized.  (Perhaps had to be run as Admin or something)
But that apparently wasn't the case.
 
So Im curious, if this is something thats a know issue, and how to fix it. Granted it doesnt happen all the time, but has me a bit worried.
Thanks.
