 Okay guys, it's time for my totally scientific approach to fan noise testing. So I'm going to be taking the GTX 580, the GTX 480, as well as the current ruler of the Roost on the AMD side, the Radeon HD 5870. I'm going to hold the camera really close to the fan so you can hear approximately how loud it is, and we will do our evaluations based on that. I'm going to make life a little bit easier for you guys this time though, and I'm actually going to cut together all of the fan noises so that you can do an easy side by side comparison. So right now we've got the GTX 580 idling, and let's get in nice and close and listen. So we're going to do our idle noise comparison, and then I'm going to follow up with a load noise comparison. For the load noise test we're going to use Furmark, so here is the GTX 580 followed by all of the other parts.
