We have to constantly say this to newbs when they question why their system doesn't match the performance of some other system that is nearly identical to theirs. I'm surprised someone who's been in the game as long as yourself would even go down that road.
Cool off Dude, as I said earlier this isn't a scientific review; this is users exchanging impressions on similar builds. There is absolutely nothing wrong with that. In fact, it might give an incentive to babalouj to re-install his block to see if he gets better results. For all we know, he might have a bad mount. Fixing this would be a positive outcome wouldn't you say?

So, I did as promised and reset my bench to exactly his settings, safe for fan voltage (could only drop to 7v as I couldn't find the 5v adapters.. we just moved in, lab is still a mess..)

Now, the current draws are nominally similar between the two cards (mine's a tad higher for whatever reason), and ambients are the same (cool day in socal):



We now observe a 7C Delta in GPU temp between the cards. The scale is such that a bad mount of his block is quite likely.

@babalouj: I'd take a look at that thermal grease imprint if I were you, and make sure you tighten everything down nice and snug when you re-install.
