I got sick of having 3 120mm fans going full blast six inches from my head while trying to sleep so I decided to get a fan controller. I hooked it up to one of the fans on my shroud while leaving the bottom 120 blowing full speed onto my 6800 gt, one to the 80mm fan cooling my hard drives and the final to the 120 exhaust fan I have. It did cut down on the noise and it makes it easier for me to sleep now but I have noticed something strange.
When I have the fans turned all the way down my GPU core is exactly the same as when I have it set to maximum and my CPU goes up a whole 1 degree celsius at full load! I tested this by running rthdrbl for about 15 min until my temps peaked then turned up the three extra fans and waited 4 min to watch my GPU temp drop by 1 degree.
What's up? Is this normal? Could this be becuase I have a decent sized shroud and the 1 fan at max and the second at low are pulling all that's needed to cool my system? I wonder if we don't need that much air and would be able to get by with a nice single 120 Sanyo Denki with a fairly large venturi shroud..
Anyway this is what my core and shroud look like
