nVidia GeForce GTX 480 Noise Comparison Idle vs 100% Fan Speed Linus Tech Tips

2010-04-12
well I've got a GTX 480 on my test bench here with a core i7 975 extreme edition EVGA classified some high-speed muskan memory I got the OCZ vertex le 200 gig SSD so this is a pretty pretty cool system anyway I'm just installing Crysis warhead right now and I've also just got an EVGA s precision tool installed and I've had quite a few people ask me about the acoustics of the of the GTX 480 okay so here we go I'm gonna set the fan speed to a hundred percent now I want to give you some idea of what it's like when you're running a game and when you're not running a game but this is just to show you what it will sound like when it's running out a hundred percent so the span speed is 45 until I hit apply 45 percent and the GPU temperature is 40 degrees at idle now I'm gonna go ahead and click apply over there and remember this system has an optical drive running full bore in the background so I'm gonna get close to that so you can hear the noise level and that's most of what you're hearing right now now just also for context I'm gonna go ahead and turn the intel stock cooler onto performance mode okay so that's what that sounds like it doesn't make much of a difference so here we go I'm gonna kick the GTX 480 here into hi here yeah that's pretty loud now I'm not sure that it'll actually run at that speed while you're gaming but like I can feel the air blowing out the back of the card here it's um it's pretty incredible anyway so there you go here I'll turn it back down to 45 before before I stopped filming here and it wasn't actually the EVGA precision so it's funny if even if you set the fan speed not to auto so there we're back to 45 even if you set the fan speed not to auto okay so you take auto off and you try and turn it down it won't let you turn it down any lower than 34 I believe yeah 34 is the lowest you can go and when you're at 34 wow you can see the GPU temperature went down three degrees just from having it on 100% for a little while now it's creeping its way back up but yeah here's what it sounds like a 34 so thank you for checking out my video on the acoustics of the GTX 480
