This is the way my rig is setup, with 2 x MSI Twin Frozr ii 2GB 560tis.
In Battlefield 3, under certain situations the top GPU will like to reach 85C + (Max 90C on two occasions) and the bottom 80C. This is running @1.025V @925/1880/2004. The majority of the time they are both in the 70C region.
*All case fans are akasa venom voodoo.
*MSI Afterburner fan profile @ 100% after 70C
*Case Fans 100% after 45C case temp.
*As the case is the Nvidia edition, I am not able to install a side case fan.
*I have spare 120mm case fans available for use.
*Also ambient temperature is quite warm, about 25-27C.
Would there be any solution available to help reduce the temps 10C or so, without taking the side panel off?
