Anybody see this?

Full load 55 degrees celsius?? Please..

GF100's maximum load temperature is 55 C.

Well, maybe they are watercooling them, else it is utter nonsense (or a hair dryer engine is providing the airflow).

Also GF104/Dual Fermi won't be able to double performance, SLI won't scale 100%, it never does, and secondly they won't be able to run it at full speed without exceeding 300W TDP.

His reply to another posted wanting more info on idle/load temps:

While I highly doubt it was in a freezer, your point is valid. If my electrical physics knowledge is any good (and it better be with a PhD....), then we should be looking at these temps:

Based on 20C ambient:

Idle range = 34-40C
Load range = 59-68C

This is based on the specs I have for a 300w heat removal solution at assumed clock speeds. Only problem is... I only helped design integration with the nMOS of GF100, not the pMOS. I'm going off the assumption that the pMOS and nMOS are joined with a Cobalt based upper gate, but I am not sure... this poses a serious problem in calculating heat production. So... these temps could be off by up to 5C, but I would think my calculations would be more in the range of ~2C of actual values.

I believe those figures only in case it's taken from an nvidia PR slide or something because for those slides they always pick games that's good for nvidia gpus and provide bad performance figures for a HD5970 and the load temp is prolly under ambient temp 0C or sth (who says it has to be 20C ambient?).

In a proper 3rd party review, the numbers wouldn't be as nice so I'm gonna stick to my original speculations that GTX380 single but highend gpu will be ~10% avg behind HD5970.
