Ambient Temp?

[jdogg707]

What does the ambient temp mean in the Nvidia drivers? My SLI 6800GT's have a core temp of 42 on Core 1 and 43 on Core 2, but Ambient temps of 68 and 69C respectively. My CPU at idle is 33C and my motherboard is 34C. What do these temps mean? and should they worry me enough to slap on a pair of VF700's?

Thanks!

i think ambient means idle

I'm pretty sure ambient means the temp inside the case

Lower GPU chip temps than ambient temps? Those numbers have to be backwards. It also sounds like they are uncalibrated relative to your CPU/mobo temps - how can your CPU temps be lower than the ambient temps around the video card?

Switching them around properly, those temps look fine to me, but I would check them under load (Prime95 + 3DMark), not at idle.

Agree with ^. Those temps must be backwards..... unless you are running peltiers on the GPUs or something crazy like that. Weird...I haven't noticed any ambient temp settings in my nVidia card properties..what driver version are you running?

Yup. Operating temperature of an FRU can't be lower than ambient, inside the case or out. Short of phase-change it just isn't possible. BTW, ambient temperature is defined as the general temperature of the surrounding environment. Both forced-air and water-cooling systems are closely tied to it.

Screenshots!

Temperature for Core 1 Driver 66.93

Temperature for Core 2 Driver 66.93

This is extremely confusing. I think the temperature settings for the cards must be wrong.

Edit:

I think for soem reason the temps are switched in the drivers, because I opened up a 3D Demo and saw my Ambient temp shoot up to 91C! The real ambient stayed around 50C.

I ordered a set of Zalman VF700's and some OCZ Ramsinks, so hopefully it will bring my overall temps.

just download Rivatuner and use that to check the temps........it has a monitoring system that can run almost invisibily resource-wise in the background while u play a game or do a 3dmark run........if you stretch it the length of the monitor screen you can see around 10 minutes worth or so........that will tell you the core and ambient temps.....
the right way round...lol
