well, i'd never even think of testing it without a hsf
mines an evga. i have had 3 evga 6800gt's, 1 agp and 2 pci-e and none approached this. of course those also are/were in my main rig, a much better case.
this is my first 6600gt. i had heard they are hotter but until i actually got the card i wasn't concerned. when i saw the layout in person i was a little stunned really. i know the agp, or i think anyway, was an afterthought on this card as it went to pci-e and they added the bridge to make it agp. i just thought they would have put some thought into the hsf they equipped it with.
i mean, not having ram sinks? better yet, the half covered rams? not to mention the hsf is just a thin little thing with a couple odd little feet on the bottom i couldn't figure out why. damn.
i think i'm going to contact evga as they have awesome support. i'd hate to send it back to newegg as its a good clocker, as i guess most are, but if i can't get a cooling solution for this it won't be any good to me.
