Well, actually one fan on the 7950 is broken, that is why I run it at lower clock than usually, so that it won't get too much heat.
My results with higher TC have been worse, 8192 gives the best results for me.. I don't know why that is so.

I bought a new fan for $14 on ebay and fixed my 5970 with just a screwdriver.
