Hi all, I am curious about my GPU. I have been monitoring temps while playing BF3, planetside 2, and crysis 3 all on the highest settings. I have reached a max temp of 71C, I know this is all fine and good considering the card will not throttle until 80C but I am worried as I plan on buying another card in the near future and having an SLI setup. Does adding a second card significantly increase temps of either card? They are enormous cards and the three fans appear to be blowing at least some hot air downward so I am a little concerned.

Also, I have one fan on the bottom of my case. Should this fan be intake or exhaust? I ask because as it is (intake) it is blowing air right at the three GPU fans and this seems a little counter productive as those fans are blowing some air downward. I have a HAF 932 so there is also a large front fan but I am worried it is not doing its job fully as I used the HD rack for a lot of cable management.

Thanks for any advice/comments. I appreciate it.

My experience in SLI with Gigabyte 670 WF3 in terms of temps and noise were quite poor (This was 6 months ago)

With one 670, I got 65 degrees with 35% fan speed, which was completely silent. When I added a second card, the temps went from 65 to 80 degrees for the top card and to 65% fan speed, which was fairly loud. Topped off with the power supply fan speed increasing as well. The temperature will go up to a fine amount, but do remember that SLIing with open air coolers like that, which blow everything (some of the DCII cards actually blow a small amount out of the case, due to the rear fan placement, so its sort of both), will often not work out well for SLI.

70C is pretty standard for that card. If you SLI, you will almost certainly hit 80C on the top card. The question is - how much will your performance get throttled? My guess? Not much. If you look at SLI benchmarks for the 770, a single card reaches 75C and SLI is 80C (and almost certainly throttled). Yet performance of SLI over single card is still in the range of +70% to +95%.

On a side note, I've found little temperature difference between basic cable management and perfect cable management, or between low and high fan speeds. As long as air has somewhere to go, it doesn't matter. In my current high-end case, the difference between no fans and expensive fans on high was 70C and 65C on my GPU and 56C and 54C on my CPU. My HDD's benefited most though, as they are close together and the fans blow right on them. They went from 30C without fans to 25C with fans. I'm sure airflow was more important back in the days of IDE cables.

Thanks for the responses guys. Can you clarify a little on the coolers? Don't pretty much all video cards have fans that blow out? I guess I'm not sure what you mean by open air. I know the air is meant to exit the back of the case but a little inevitably seems to blow downward.

I am not totally sold on SLI yet, but may give it a try when prices go down a little. I may just just buy a new card with more vram in the future too, not totally sure.
