GTX275 PhysX Edition Temperatures
Benchmark tests are always nice, so long as you care about comparing one product to another. But when you're an overclocker, or merely a hardware enthusiast who likes to tweak things on occasion, there's no substitute for good information. Benchmark Reviews has a very popular guide written on Overclocking the NVIDIA GeForce Video Card, which gives detailed instruction on how to tweak a GeForce graphics card for better performance. Of course, not every video card has the head room. Some products run so hot that they can't suffer any higher temperatures than they already do. This is why we measure the operating temperature of the video card products we test.
But the EVGA GTX 275 CO-OP PhysX Edition's two GPUs normally handle separate loads, and only the GTX 275 GPU can be used for rendering. I used Furmark to load the GTX 275 GPU, and the NVIDIA GPU-optimized version of Stanford's Folding@Home client to simultaneously load the GTS 250 GPU.
Starting with an ambient temperature of 24°C, I used GPU-Z to measure a surprisingly high idle temperature of 45°C for the GTS 250, and a more reasonable 40°C for the GTX 275. The test system is an "open" chassis so internal case temperature was not a concern. After running FurMark 1.7.0 and Folding@Home for 15 minutes, the load temperature stabilized at 64°C for the GTS 250 and 79°C for the GTX 275. The design of the card's cooling system means that warm air from the GTX 275 is expelled into your case, and in high load situations, there's rather a lot of warm air! You should make sure your case is well-ventilated.
