Yup, just finished installing a third evga 570 and at 99% load they range from 41-43*C folding.

Of course, after reading the "who burned up a gtx570" thread they are all dialed back down to a VERY modest oc...

I realized the top card had hotter air to work with, never thought of a greater workload.

My SLI 570's get between 3-8* or so higher on top, with stock cooling and fans turned up a bit.

Try plugging in your monitor to the bottom card, that usually helps a bit with temps on the top card.

I would say 'physics' and 'thermal dynamics'.. or to put it simply.. heat rises

Also there could be mfg problem or difference with the top card beyond what every one has expressed. Couple of things to try would be to take out the second card and see if the temp remain high. Then swap into the top slot the card you removed and see if it is still running cooler by itself. It it is you can test it with the other card as the second device
