GTX 680 SLI Temps and Space

post #1 of 4
Thread Starter 
Hello,

I am debating on getting 2 GTX 680 4GB for SLI configuration. I am quite worried about the temps of my case.

I have a HAF X case, it has plenty of room of course, and I am running a Gigabyte Z77X-UD5H MOBO. If I were to SLI them, they would be cutting it pretty close to each other, seeing that my MOBO only supports 2-way SLI. I have read plenty of reviews of temps sitting around 72-80C with a good space between them.

I am just wondering if anyone has the same MOBO (or one similar) and case as myself that can relate their temperature experiences.
I am probably just going to get the TITAN because I do not want to get SLI 680's and then be limited on the performance I can get out of them because of the 70C temp throttle. There would not be much if any room for overclocking the SLI setup whereas the TITAN can be significantly overclocked due to all the new technologies and make up for the 10-15% performance difference against the SLI 680's

I have read that the reference coolers are better for SLI due to getting the heat out of the case. But if I cannot keep BOTH of them under 70C at full load and gaming, then I am getting the TITAN. I just don't want 2 cards that I spent a grand on that I can't push to the max because of temperature limits. I do not have the option of a water-cooled system so they will have to be reference air cooled.

With the TITAN, I can set the temperature throttle point to my liking, which allows for a much better SLI setup in the future as well, being able to set each cards temperature throttle limit separately

Don't worry about the 70 degree throttle. What I've found is the performance loss is really minimal, my cards (670's) only downclock around 13 something mhz, which is like nothing and not noticeable. I let my cards run up to 80 degrees celcius so that I can have quietness.

In heaven I noted maybe at most a 1.5 FPS difference between letting them run at 70 degrees and running them at 80 degrees.

Here we go, just did some testing on Valley.

With the Top card running at 66 degrees and bottom card running at 58 degrees, with Valley 8XAA maxed out 2560x1440,

Avg FPS: 47.1
Min FPS: 23.5
Max FPS: 90.3

With the Top card running at 87 degrees, and the bottom card running at 70 degrees (Today was a hot day), with the same settings as before:

Avg FPS: 45.8
Min FPS: 23.7
Max FPS: 86.9.

Pretty minimal for almost a 20 degree difference.
