We got some word that Nvidia's upcoming Fermi-based Geforce GTX 480 single GPU card should be as hot as the GTX 285. These are still preliminary results, as Nvidia still has to send out the final cards with the final coolers, but this looks like slightly better result that the GTX 480 that we saw at CES 2010.
The
TDP of the GTX 480 will end up higher than on GTX 285, but with the help of a good
cooler the thermals should be very close.
The noise lever should also be very comparable and the card should not end up much noisier than GTX 285. We heard numerous times that GTX 480 will end up with different cooler than the one we saw at CES 2010 and that was showed to Nvidia's loyal press at Editor Days.
All in
all, you won't burn your fingers on the GTX 480, but it won't be cold either.
