Crossfire card temp differences?

[blueonblack]

I'm running two HD 4670 cards in Crossfire, each with the exact same cooler. Bit for some reason GPU-Z shows a 20-degree difference in temp between them, with the one my monitor is actually plugged into running hotter. Is this normal? I thought Crossfire utilized both cards, regardless of which was actually sending the signal to the monitor?


Edit: Ok, this looks like a software issue. The instant I start rthdribl to stress it, the temp jumps 18 degrees on the primary card. The instant I shut it down those extra degrees vanish. Is GPU-Z this buggy? Can anyone reccomend a good temp-monitoring program for ATI cards? I loved Nvtemp with my old card, it was simple, unobtrusive, and effective, but I haven't found anything like it for ATI.

The new ATI Catalyst Control Center with the built in overclocking functions will give you a current GPU temperature reading on the overclocking page (I mildly OC'd my 4830 to 600MHz and my temps stay under 55C).

also the heat from 1 card rise heating the one on top more also under load unless the program is cf cablable you could be rendering most things off 1 card only.. since 2 isnt always used..
