I agree, the front of my case has room for a total of 4 80mm fans, I currently have 2, I may have to throw another in there or at least reposition them and see if that helps a bit.

The cards are getting up close to 80C at load (with no OC). I'd like them to get to these temps WITH oc, so I need do work on ventilation a bit.

I'll try and post some pictures when I get home. I cannot find pics anywhere of two cards this close together in SLI.

Basically (asus p5n-d) + (eVGA 8800GTS 512mb SLI) = insane crowding.

I'll have to try and get some more ventilation, but it is more a matter of the cards getting enough air, not just cool air. Although I worry because the top card is pretty much sucking the hot air right off the bottom card's PCB.

Here's the pic, look how freakin close together these cards are:


**Yes, I know the bottom card is not screwed into the case, I took this pic when I was building the system.**

It is really screwing with my temps too, check out these temps:

With ambient: 77F
Bottom card -- Idle: 54C, Load 59C (with 100% fan speed)
Top card -- Idle: 65C, Load 73C (100% fan speed).

I don't know anyway of keeping the top card cool with so little airflow and the little air it has is the hot air coming off the bottom card.

Granted 73C isn't insanely hot for a GPU, but I'd prefer to OC the card further, and I'd also like to avoid using 100% fan speed when I can.

Reading around and the ports on this board are simply too close together, nothing I can really do about it other than change the cooling solution on the cards or get a different board.
