Arronleeds :
ive just turned my fans off on my gpu and it stayed at the same idle temp as it did with the fans on, around 31c.
my gpu in the winter idles at 20-24c
sware it used to idle higher than that with the fans off.
If you did like me and built your PC with having a good air flow as a priority, most of your components probably run cool at all time. It's great that it runs cool when you turn the fans off, but it also proves that the fans weren't doing much at idle.
If you don't mind me asking, what are your current clocks on the core and memory?
