Well I got my other card today. Works good but it runs hot and uses more power than my other card which gives it zero room to overclock. I tried reapplying the tim on the card and it didn't help drop the temps.
Got 180 fps in heaven benchmark with the cards at stock clocks. 
Do you think that could be attributed to the difference between any two cards. No two cards are the same. At idle my card runs about like your second card (~30C). In F4 it'll run up to 62C, and there the GPU clock is about 1750MHz to 1800MHz. I'll double check again this evening and post back here. Stock clocks, right?
I guess my point is, that doesn't look alarming to me.
