Cooling and Noise
For both our noise and cooling performance testing we put every card under more load than you would ever see in everyday use. To say that Furmark is an extreme situation is an understatement. We use it because we want to see what the cards cooler design will do when pushed to the limit. This also gives us a chance to test the cards noise output as well. All testing is done with a room temperature of 70 degrees.
As you can see above the GTX 670 did get a little warm, very similar to the GTX 680 that we tested in the same way. In fact we saw it get two degree’s warmer than the GTX 680, but I would imagine that this has to do with the more compact PCB that we spoke about before. In our in game benchmarks the card ran cool, only pushing beyond its limits with Furmark did we see these temperatures. With the GTX 670’s cooler pushed to the limit I would have expected it to crank up and put out ear piercing noise like most cards but I was impressed with the cards noise output. At Idle and in normal gaming situations we experienced a little noise on the test bench, but nothing that you would ever notice in a real case.
