Hi,
as mentioned in the forum post below, a patch was floating around to allow reading temperatures in asus 8800GT cards, using nvclock 0.8 beta3:
http://sourceforge.net/forum/forum.php?thread_id=2065784&forum_id=67426
It seems to me that the logic of this patch has been included in 0.8 beta4, so that it should work... But it doesn't.
AFAICS this is because of a one character change in beta4, compared to the patch for beta3. The attached patch corrects this, and works for me.
Regards,
Nicolas
