I am running 2 geforce 7800 GTXes in SLI. I have a CM stacker (STC-T01) with both of the sides open. GPU1 is idling at 59 =C, and GPU2 is idling at 53C. On load (BF2, 1920x1200 max setting) they can go as high as 89C. (room temp is ~23C)
I am wondering if that's too hot for idle and load?
Here is my rig if it matters:
ASUS A8N-SLI Deluxe
eVGA Geforce 7800 GTX (In SLI)
OCZ Titanium 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Kit System Memory (2-3-2-5)
AMD Athlon 64 X2 4800+
Creative SB Audigy 2 ZS (WDM)
Seasonic S12 600w Power Supply
1x Seagate Barracuda 7200.7 SATA NCQ 3Gb/s ST160827AS 160GB 7200 RPM SATA Hard Drive
2x Western Digital Caviar SE16 WD3200KS 320GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive (RAID 0)
I have 3 in flow fans (stock 120MM fans from the stacker) and 1 out flow fan (a 120MM alienware fan, has quite a bit of CFM for the same noise as the stacker ones). But that shouldn't matter since the case sides are open.
I am not to sure about the 7800 GTX but I do know that the threshold temperature of the 7900GTX is 110C and I wouldnt think that the 7800GTX would be too much different. MY 7900GTX does idle around 54C, even when not in SLi.
