Cards Throttling Around 100c

[rograz]

Powercolor 7950's have the worlds shittiest cooler on it...

Looks like an overgrown Pentium 4 cooler with no heatpipes at all.

I think what you are referring to is the reference 7950 cooler, it has a vapor chamber but as you say it is quite useless. Only good thing is that the cards with those coolers should also come with the reference PCB and guarantee that the cards aren't voltage locked

I'm mining Litecoin so yes I need scrypt..   But it's been running for a month now non stop.. I guess I'll run it til dead, two year warranty.

Stock 7990 cards all run at over 100c when you first put them in.  I wonder if I can under volt the7990 cards.
Anyone know of a solution?

 Have you downclocked your memory as low as it will go ? Try taking it down to 685 (or lower if you can), and that should allow it to run cooler.

 Don't need your VRAM clocked high while hashing... unless you are doing Scrypt stuff, then, well, yeah, I guess 100C is possible.
