All- I'm new to Rivatuner. I would not have found/used it if it weren't for the new 9600GSO I picked up for my VMC rig. Here's the deal: The fan runs 100% all day...it's loud, and quite annoying...not to mention, the toughest thing that machine does all day is media center, and sitting at 42*, I see no need for 100% fan at all. I have installed Rivatuner 2.20 with Forceware 180.48 (i think). I followed the article for setting up the fan controls etc...but to no avail. I do NOT have the checkbox for "enable low level fan control"...only a dropdown for auto/manual and the only slider that works is the 3D slider. Also, I was not able to set any threshholds on core temp for different fan profiles to activate....they just weren't there. So long story short, I have no control over the fan speed...I can't change it. I have tried the 173.23 (I think) forceware drivers- which did not change anything. Am I missing something? Is there some advanced setting that I need to enable, etc? Vista Ultimate x64 Any information, or articles, or anything for me to read up....any help is appreciated. Thanks!
