Motherboard Getting Hotter After Using Ati Crossfire

[micksax]

Hi,

 

I've just added another HIS 4870 graphics card to my system and now have two of these cards running in crossfire mode on my ASUS P5Q Pro m/b.I have overclocked my E8600 CPU to 4.5 Ghz and everything was running reasonably cool up until I installed the second card.With both cards the m/b temp is up to 49 degrees which is 8-9 degrees hotter than with a single card.Do you think that dropping the overclock down would lower the m/b temp and if so,by how much,or does anyone have any other suggestions on how to lower the m/b temp while retaining most of the performance.

It'd be helpful if you listed all of your system's specifications, especially the case in use, I'm poised to think a fan would solve your problems.

The case I'm using is the Antec 900.I have a 200mm fan which sits on the inside at the top of the case plus I also have 5 x 120mm internal fans and a Zalman CNPS9700 NT CPU fan/cooler.Thanks.

How much voltage are you running through the NB Core?

Correct me if im wrong, but doesn't enabling crossfire/sli put a heaver load on the south bridge? if so, I would expect an increase in temp's.
