I am running 460s at 850mhz @ 1.075v (one of them is a pretty miserable clocker, and I am debating sending it back)
My big question is whether these temps I am seeing are normal. I have reapplied TIM twice and same result. Heatsink is getting plenty hot so I am not worried about heat transfer. Also have a custom fan profile running which does well.
My temps are as follows: (assume 850mhz and 1.075v)
Idle (SLI On) - ~49C on both
Idle (SLI Off) - 44C Top 36C Bottom
Load (SLI On running BC2 @ Max) - ~72C
Load (SLI Off w/ Kombustor on 32xAA/Max Res) - 65C
I realize the load temps seems fine for SLI, but I am wondering why these cards don't clock down for idle when SLI mode is enabled... seems like a hot idle to me.
CPU is watercooled, and the Case Intake is the 240 rad which has ap-15 gentle typhoons push/pull on it. Air coming off it is aimed directly at the cards and is not warm. Still running a 140mm top exhaust and a 120mm high speed yate for my rear exhaust by cpu socket. (moves a TON of hot air during GPU load)
I guess these seem relatively normal ? (its more than enough power for me considering i run a 1680x1050 monitor (for the 120hz =D)
My top twin frozr idles @28 C while my bottom one is @ 25C
