I am not quite sure what to do about this. I recently bought a new 4k monitor (see here for discussion), and I thought that I had better get two 980Ti cards to put in SLI to ensure that performance in 3d applications/games was serviceable given what I had read.
I initially installed just the one card for testing, and this worked reasonably well (average of 34fps on the The Division benchmark with the automatically selected settings, which were mostly at maximum apart from the special NVidia shadow settings and anti-aliasing), but with some room for improvement. I spent some time wondering whether to proceed with SLI because it would mean removing my PCI Creative X-Fi sound card and relying on built-in audio (albeit with the ability to add a PCIe sound card in due course), and eventually decided to do so.
Having installed the second card, however, I find that the temperature of one of the two cards gets so high (often up to 91C) that the clock speed is throttled to circa 500mhz (the default with this particular card, the MSI Gaming 6G is in excess of 1,300mhz), which makes the framerates significantly lower (in The Division, at least) than with a single card, the benchmark recording average framerates in the 20s after a few passes (whilst the card heats up). Playing the game, the framerates are usually reported in the teens. With a single card, they were in the high 20s outdoors and in the 40s indoors.
With a single card, the temperature would reach about 83-84C and the card would be reduced to about 1,100Mhz and remain fairly stable there on the The Division benchmark.
There are only two PCIe 16x slots on my mobherboard, so I have no choice of spacing the cards more widely than they are spaced at present. There is only a tiny gap between the two cards - indeed, I had to use one of the plastic caps that covered the DisplayPort sockets to push the cards apart a little to stop the fan of the no. 1 card rubbing on the backplate of the no. 2 card.
The case is a reasonably decent Antec with sensible provision for airflow: I have added a fan at the front to the existing rear and rear top fans (and replaced those with models that are more efficient and less noisy), and I am not sure what else that I can do about airflow.
Having unpacked the card and install it, I cannot now very well send it back, and I should hate to have to sell the thing secondhand just after having bought it, thus losing a considerable proportion of its value for no sensible gain.
Has anyone any suggestions of what, within reason, and without making my computer sound like a jet engine, might be done about this?
Edit I should add that I tested disabling SLI in the software without physically removing the second card, and the results were worse than with SLI enabled. SLI is definitely working, as both cards report significant GPU usage, although The Division is not as well optimised as it might be for SLI, so usage on one card is greater than on the other.
