ASUS GTX 580 Direct CUII heat problem?

post #1 of 5
Thread Starter 
I currently own a Gigabyte Z68X-UD4-B3 motherboard.

I want to get the ASUS GTX 580 Direct CUII in SLI. There won't be any slot in between the two cards.

Would this be a huge issue with heat?

Would the top card over heat?

Does anyone have this set up before as well?

I won't be OC the cards. Reason I want this version is just the cooler looks very nice. If it will cause heat issues with my current motherboard I can always look for the reg. design ones.

Thanks for your input!

The board looks like the same spacing as the p67a-ud4, two Direct CUII will fit but without much breathing room for the top card.

I've run two in SLI on several Asus P67 boards that have minimal space between them. The top card will run a bit hotter but the DirectCU cooling can easily accomodate the additional heat.


Since you are using the Corsair 600T, I'd suggest you get the optional door and mount a couple of fans in it (unless the special edition includes this option?). Nothing beats door fans for directing cool external air into video cards.

Yup already have a 120mm fan blowing directly at the Video card slots.

So it will run a bit hotter but within 'specs' right?

These 3 sources all report that the top card loads at mid 70's, with one empty slot between the two cards.

From the guru3d review, a single card loads at mid 60's. This implies going from no obstruction of airflow to having just one empty slot for airflow will raise the load temp of the top card by 10C, say.

So, I estimate, when there is no empty slot at all, the top card would go into the mid to high 80's easily. Notice this is already with excellent case ventilation. If this area is not done well, I think it might go into lower 90's.

In conclusion, if you have excellent case ventilation, the top card's temp should stay in the mid to high 80's.
