Actually.... it isn't sorted out. Last night I got out the power tools and cut a section out of the motherboard tray so the bracket wont hit and since I had it apart, decided to cut out the rear exhaust grill and top exhaust grill. This seems to have cut the noise from these fans by about 50%. Less restrictive metal mesh, less noise. I also painted the back of the case with some Rustoleum gloss black high temp enamel. Great paint!

As for the CPU temps.... they are STILL 10'c apart. For kicks, i've got one of those Dynatron 1U copper micro-fin CPU coolers around here somewhere which i'll install to see if that gets the same results since it uses a back brace. The intel cooler had push pins.
