Watercool the cards would be the best way but you would'nt get much change from £150 and that's just using core only blocks. Full cover blocks would be much more expensive.

Yeah being a student a proper water cooling solution isn't really a viable option. The card being a non reference design probably doesn't help either.

those slots are ridiculously close....are all i7 boards like that

Its worse than ridiculously close, the cards actually touch and bits from the back of one card can block the fan of the one behind it, I've remedied this problem uncreatively but it there are still airflow issues. I don't know if it is representative of the X58 or P55 boards as a whole though.

What are the temps like with the stock coolers? My old 4870 crossfire setup ran cooler with the stock coolers than it did with both cards under an accelero twin turbo. This wasn't due to the cooler - the twin turbo is amazing with a single card, but rather the spacing.

The aftermarket cooler was thicker than the stock job, meaning there was less room for cool air between the cards. It also had less directional airflow than the stock ones, the stock jobs suck in air and dump it out the case, the aftermarket ones hardly exhausted anything - raising ambient temps local to the cards.

Another less likely possibility is that your install of the coolers my have been less than superb - doutful though judging by the sounds of how many times you;ve swapped them over.

With the stock cooler my temps were pretty much the same. I thought that maybe if I had a cooler which vented hot air directly out it may help the situation, but unfortunately it didn't really do much.

@twist3d0n3 :
The NB and SB temps are probably related to the GPU temps. The SB is located under the heatsink which is under the tail of both graphics cards. The NB is located above the first graphics card and all the heat from that card radiates onto that heatsink. Also I believe both NB and SB are connected by a heatpipe.

You should be able to get hold of some longer crossfire bridges because my ASUS M3A32-MVP came with 2 of them.
