Problem with hheatsink position

[domyboy]

Hello, im having a bit of a problem with my gfx card temps and cpu temps, i know the reason but im not sure what to do as i cant move the Thermalright cooler to another position. Here is a pick of the inside of my comp(i know its messy cos its getting stripped out tomoz). The Thermalright vga heatsink is on my HD2900 Pro, the heatsink above it is cooled by a 80mm Noctau fan however it blows the hot air right into my AC Pro7, if i mount the Thermalright heatsink the other way the hot air will need to be blown down which makes it harder as convection of air makes it want to rise, it will also be harder to get the air out as it would be blowing it directly onto the metal panel that covers the Corsair HX620. Can anyone think of a way I could mount the Thermalright vga heatsink so that it gets cooled properly, without heating up my AC pro7?
(its an antec p180 case btw)

Cheers Dom

I eventually moved the heatsink underneath the HD2900 PRO and the GFX temps have dropped 20c! however my CPU temps still remain pretty high, after lapping both the E6400 and AC PRO 7 and applying Thermalright thermal paste, the idle temps are 42c which to me along with all the fans and lapping dusnt make sense. Can anyone give me any ideas to further reduce the CPU temps?
Cheers Dom
