NVIDIA GeForce GTX 660 Ti SLI Performance Analysis
Temperature & Power Consumption Results
Temperature Results
Temperature performance on the GTX 660 Ti will obviously depend on which custom cooler(s) you're set of graphics cards are using. Case in point, for our system, we chose MSI and Gigabyte (which were down-clocked to reference clock speeds). To keep our result chart clean, the 'reference' GTX 660 Ti single card temperature result is based on the MSI model. Take note that it's overclocked out of the box, but it had the best temperature performance among the premium GTX 660 Ti graphics cards (and thus a closer representative to the non overclocked reference model).
As you can see from the compiled temperature test results while at load, the pair of GTX 660 Ti cards registered a significant increase in heat, although this was expected and is in-line with the rest of our SLI and CrossfireX setups. Your own mileage will vary depending on which pair of graphics cards you've SLI'ed and if they are overclocked, they will register much higher temperatures too.
Power Consumption Results
Power consumption will also differ from model to model, but it shouldn't vary as much as temperature results. Compared to our other 2-way configuration setups, the GTX 660 Ti par was fairly good, losing only to the HD 7870 CrossfireX setup. This is to be expected since the GPUs used on the GTX 660 Ti are identical to those used in GTX 670 and GTX 680.
