I recently bought another 770 for my SLI setup, im using MSI afterburner to get an overview over temps and the temp limit option doesnt work properly because the card goes up to 95+ degrees, its only the first GPU that gets really hot, probbably because there is no space between the cards and its only the second GPU that gets good airflow i guess. But i dont understand why the temp limit doesnt work, and the only way i can play games on max like for example crysis 3, is if i set the gpu fans to 100% and blast the case fans all the way up. This way the temperatures stays at about 80 degrees. So i guess what im asking is: is it ok to let your cards go at 100% fan speed when you are gaming? is there any way to make the temperature limit work? Also im going to try and move the cards 1 slot apart if theres space and see if that helps any. The case is antec 1200

While crossfiring or doing sli GPUs heat up more than running as single gpu, not only for the room that is left between the two but also because its more demanding for the chip. The top GPU will always have higher temps than the bottom one. That case has very good airflow, if you use all the fans and more importantly, the side fan to cool the cards.

How did your temps turn out? If possible, you could always see if someone would want to purchase your cards and you could get a couple of reference design cards which blow air out of the back. This could drastically help with temperature if you wanted to go through the hassle. Or case could have done the trick. I would recommend case fans such as the Corsair SP120 Quiet Edition. They have great static pressure and will be able to pull air more effectively through your side panel. If you want to get more than 1 I would recommend getting the twin pack (I would recommend this even if you do not need more than 1) as it is normally only about 10 or less dollars than the single.

Make sure there is at least a 1 slot space between them. If your motherboard is like mine and has 3 slots, don't put it in slot 1 and 2, put them in slot 1 and 3.

Also, make sure they are in the right slots. PCI-E X16, not X4 slot.

Make sure that you read your motherboard manual for placement of cards. Most motherboards will set both of the cards to x8.

It survives at 88 degrees maximum, when im running at 100% fan speed, i also found out my motherboard only has 2 slots for pci express.

Is there a space between them? That temperature is pretty high.

Also, what is your case airflow like?
