well GPU launch day wouldn't be complete without a Linus tech tips evaluation of the temperatures of the new card under idle and load conditions so remember that the load that I'm going to show you today is going to be kind of a worst case scenario running fir mark and the idle is well that's that's a pretty typical scenario but it's still a bit of a best-case because I am running on an open test bench and your CPU CPU Wow your computer case is actually going to keep things a little bit toasty er than an open test bench just because of the recycling of the air that's being used to cool the components so our idle temperature for this brand-new GPU from Nvidia is actually 38 degrees and it does that at a fan speed of about 40 percent well exactly 40 percent which equates to almost 1,400 rpm and yeah so that's fairly straightforward isn't it so I'll show you the low temperatures as well as compare it to its predecessor which was often criticized for running too hot the GTX 480 for the GPU load comparison on the GTX 580 you can see I've got fir mark running here in extreme burning mode and you can see the the rise in temperature while I held a piece of paper over the intake of the fan so that it wouldn't so that I wouldn't heat up pretty quickly so that I could get my results and you can see it actually settled down into a temperature of 69 degrees Celsius okay you can see that is backed up by afterburner over here with the fan running at about 53 to 54 percent which is about 1920 rpm so it's not bad at all nuts quite cool compared to other Fermi based cards mind you this is GF 110 not GF 100 that we're talking about it's a whole new beast the idle reading for the GTX 480 really does tell the story despite this card being significantly less powerful than the fighting it runs significantly and I am over using that word hotter than the GTX 580 so it idles at a whopping 47 degrees and that's with a fan rpm of over 1500 RPM bear in mind these are using a fairly similar fan although the cooler design is quite different because the GTX 480 uses heat pipes whereas the GTX 580 actually uses a vapor chamber design that is hidden by the plastic shroud so if you weren't aware already yes GTX 480 s reputation for running toasty is well enough deserved so we've got the fan rpm up around almost 3000 rpm with a speed of 71% and we are still at 92 degrees that's very very hot especially considering we are running on an open test platform in a reasonable temperature room now when you have a GTX 480 running non-stop in in a normal sized room it will actually heat up the room several degrees so that fan is actually going to go higher when it's inside a case in a warmer room so the GTX 580 is a huge improvement over the GTX 480 in that regard I sure wish I had something newer from AMD to compare against the GTX 580 wink-wink nudge-nudge but I guess the 5870 will this have to do for now so you can see we're running at above 38 degrees and that is with a fan speed percentage of only about 20 percent so we'll show you the load temperatures and that'll be in just a moment so I guess we kind of know this already but there we go the 5870 it's been on the market for a while it loads at about 85 degrees with a fan speed of yeah only about 37% so you could tweak the fan profile a little bit if you wanted set it up so that that fan ramps up a little bit more and gives you a better temperatures but honestly it's not necessary it's designed to run just fine that temperature like I said will have something better to compare this with the 580 against compare against the 580 from AMD fairly soon thank you for checking out my video on the temperatures of the GTX 580 against its nearest competitors and the single GPU market don't forget to subscribe to - tech tips
