That entire heatsink on each card is saturated at 50C! Holy hell on a crutch!
Are those IR pics accurate? That seems excessive... if it actually is 40 - 50C, what's going to happen to them in hot weather?
Maybe Jeff can heat up a room to 85F or so and let it run to see what happens.
Is 50C really a problem? I had the impression that even 80C isn't a problem? My GPU is at 62C right now not doing anything.

Remember that the hotter the heatsinks get the more heat they dissipate. Both by radiation but also by warming up the exhaust air more. If Jeff's room is 20C now and he heated it up to 35C I don't think we would see an increase to more than 60C, with the fans running at the same speed.
