this is going to be a quick video on the temperatures and noise of the radion 6870 so I've got my handy dandy little thermometer here showing us the room temps because remember if the room temperatures go up by even one degree then the card temperatures will go up by exactly one degree those are the rules they must be obeyed so whenever you're comparing temperatures you have to remember you have to know the ambient temperature so here you can see we have a 41 degree idle at a 22 and a half 22 to 23 degree room temperature we're going to treat this as sort of plus minus one I mean look how sensitive this thing is if I put my hand next to the probe over here watch the temperature skyrocket just from the heat my hands giving off I'm not even touching the thing pretty crazy so you got to sort of see look at that it's already up to like 25 degrees just because of the heat from my hand anyway so here it is at idle it's basically silent at idle it's got a little bit of a little bit of fan normal fan sort of a grinding noise within probably about 12 to 14 inches but beyond that and especially inside a closed case you will not hear this thing so a 41 degree idle silent now let's see what it looks like under a gaming load now we've got what would represent a worst case scenario gaming load so you can see the room temperatures here and you can see that running fur mark in extreme burn mode is going to yield an 83 degree temperature you can also see that the whoops fan speed has ramped up a fair bit Wow not really much at all that's incredible oh wait no it has it's just not detected by afterburner okay so you can listen you can compare those two clips against each other so it is quite a bit louder but still quite tolerable especially for like a performance like a mid-range performance graphics card so I'm going to give you just some comparisons against the GTX 480 there's full speed in case you were wondering but I'm going to give you some comparisons against the GTX 480 as well as the 5870 just so you got a reference point here's the 58 70 for my noise comparison get it nice and close to the fat now the 58 70 is attached louder than the 68 70 at least for my particular samples um one thing that I mean those fans look so similar but it almost looks like the new fan is a little bit bigger you know what I'm going to compare that justice I know the fan is exactly the same diameter for some reason there's a little bit more word to this one it could just be that it's older it is a bit of an older card so you can see that my idle temps on this particular card are 38 degrees place you'd be able to see that if my camera could focus on a monitor for a change maybe that'll help there you go 39 degrees 38 degrees and then my room temps are around 20 to 23 degrees so there you go now we'll ramp it up now bearing in mind that this is a more powerful card the noise level is quite a bit louder and it does get hotter so it runs at about 90 degrees using the default fan profile remember with afterburner you can always change profiles around if you want so you can see we're running at about 44 percent on the fan speed and 87 degrees on the GPU I think I already set that yeah I already said that so I'm just going to show you just for context so remember fur mark is pretty much a worst case scenario for a game running like absolute worst case scenario it won't get this hot it won't get this loud in any sort of real game and this is only if you set it manually but I'm going to go ahead and turn it up to 100% to see it there you go okay moving on and finally for comparison we had the GTX 480 which is in some ways the top dog in terms of noise generation due to the power and size of the GPU inside it so you can see our idle temperatures are a little bit higher than the other two cards that we were looking at at about 50 degrees my room temps just for your reference are around the same they're 23 and a half degrees okay and then in terms of fan noise you can see that fans barely spinning I mean look at this it's not going very fast at all this is quite a quiet card at idle but it's a bit of a different story under load so our GTX 480 peaked at around just over 90 degrees under load can see here infer Marc I want to stress again but not only for the GTX 480 but for the other cards that we're looking at here that fir mark represents an unrealistic gaming load it's mostly a tool for finding out the absolute max temps and making sure that your card is 100% stable with an overclock so there's your reference point for listening to it and just for fun I'm going to turn this one up to a hundred percent if you really want to blow your ears off quite quite loud at that particular setting so go ahead and put it back to auto I mean bear in mind the GTX 480 does ramp up to about 80 percent fan speed under under an intense load like this anyhow
