Yup, just spent 3 hours re-wiring my case for better cable management, and put an 80mm fan inside shooting up towards RAM and Northbridge in a very ghetto, twisty-tie style. After all that work, I only see a drop in temps maybe 2C and still can't OC any further (so maybe its not a hot NB after all). So that was a total waste of time, not to mention there is a fan twisty-tied onto power cables in there. Can't be good news.

Well...Whatever. In a couple months I'll just get a water-cooling system and get a NB and VGA waterblock. If I can over clock more from lower temps...awesome. If I can't, well I guess I just have a cooler running system.

Final Specs:
E6400 OC to 3.0 Ghz at 1.34 Vcore
2 gig of Corsair XMS2 DDR2 6400 at 2.10v (running 5-5-5-12 @ 730Mhz)
Leadtek 7900GT 560/760
Silverstone Zeus PSU
And an additional fan twisty-tied down inside the case..woo woo.
