00:00:00.520 --> 00:00:09.080
this is going to be a quick video on the temperatures and noise of the radon

00:00:06.279 --> 00:00:12.880
6870 so I've got my handy dandy little thermometer here showing us the room

00:00:10.759 --> 00:00:18.000
temps because remember if the room temperatures go up by even 1° then the

00:00:16.000 --> 00:00:22.240
card temperatures will go up by exactly 1° those are the rules they must be

00:00:20.119 --> 00:00:26.679
obeyed so whenever you're comparing temperatures you have to remember you

00:00:24.760 --> 00:00:30.960
have to know the ambient temperature so here you can see we have a 41° idle at a

00:00:29.599 --> 00:00:36.200
2 2 and 1/2 uh 22 to 23° room temperature we're

00:00:34.719 --> 00:00:42.280
going to treat this as sort of plusus one I mean look how sensitive this thing is if I put my hand next to the probe

00:00:40.399 --> 00:00:45.760
over here watch the temperature Skyrocket just from the heat my hand's

00:00:44.399 --> 00:00:49.280
giving off I'm not even touching the thing pretty crazy so you got to sort of

00:00:47.960 --> 00:00:54.920
see look at that it's already up to like 25° just because of the heat from my

00:00:51.160 --> 00:00:54.920
hand anyway so here it is at

00:00:55.960 --> 00:01:03.719
idle it's basically silent at idle

00:01:01.440 --> 00:01:08.880
it's got a little bit of a a little bit of fan normal fan sort of a grinding

00:01:06.280 --> 00:01:13.280
noise uh within probably about 12 to 14 in but beyond that and especially inside

00:01:11.240 --> 00:01:18.640
a closed case you will not hear this thing so 41° idle silent now let's see

00:01:16.640 --> 00:01:22.360
what it looks like under a gaming load now we've got what would represent a

00:01:20.240 --> 00:01:26.240
worst case scenario gaming load so you can see the room temperatures here and

00:01:24.520 --> 00:01:32.399
you can see that running furmark in extreme burn mode is going to yield an

00:01:28.840 --> 00:01:34.000
83° temperature you can also see that

00:01:32.399 --> 00:01:41.799
the whoops fan speed has ramped up a fair

00:01:36.680 --> 00:01:44.040
bit wow not really much at all that's

00:01:41.799 --> 00:01:47.280
incredible oh wait no it has it's just not detected by After Burner okay so you

00:01:45.600 --> 00:01:51.960
can listen you can compare those two clips

00:01:49.680 --> 00:01:56.320
against each other so it is uh quite a bit louder but still quite tolerable

00:01:54.320 --> 00:02:00.280
especially for like a performance like a mid-range performance graphics card so

00:01:58.479 --> 00:02:04.520
I'm going to give you uh just some comparisons against the GTX

00:02:05.840 --> 00:02:12.080
480 there's full speed in case you were wondering but I'm going to give you some

00:02:09.879 --> 00:02:18.720
comparisons against the gtx480 as well as the 5870 just so you got a reference

00:02:14.599 --> 00:02:21.599
point here's the 5870 for my noise

00:02:18.720 --> 00:02:27.920
comparison getting nice and close to the fan now the 5870 is a touch louder than

00:02:24.920 --> 00:02:30.959
the 6870 at least for my particular

00:02:27.920 --> 00:02:33.760
samples um one thing that

00:02:30.959 --> 00:02:36.760
I mean those fans look so similar but it almost looks like the new fan is a

00:02:35.680 --> 00:02:41.360
little bit bigger you know what I'm going to compare that just a sec uh no

00:02:39.480 --> 00:02:44.000
the fan is exactly the same diameter for some reason there's a little bit more

00:02:42.519 --> 00:02:47.840
wor to this one it could just be that it's older it is a bit of an older card

00:02:46.280 --> 00:02:51.640
so you can see that my idle temps on this particular card are

00:02:49.599 --> 00:02:55.800
38° at least you'd be able to see that if my camera could focus on a monitor

00:02:53.280 --> 00:03:01.720
for a change maybe that'll help there you go 39° 38° and then my room Temps

00:03:00.080 --> 00:03:08.080
are around 22 23° so there you go now we'll ramp it

00:03:06.120 --> 00:03:12.080
up now bearing in mind that this is a more powerful

00:03:12.080 --> 00:03:18.560
card the noise level is quite a bit louder and it does get hotter so it runs

00:03:16.319 --> 00:03:22.280
at about 90° using the default fan profile remember with afterburner you

00:03:20.040 --> 00:03:28.799
can always uh change profiles around if you want so you can see we're running at

00:03:24.120 --> 00:03:30.480
about 44% on the fan speed and uh 87° on

00:03:28.799 --> 00:03:36.200
the GPU I think I said that yeah I already said that so I'm just going to show you just for context so remember f

00:03:33.680 --> 00:03:41.400
mark is pretty much a worst case scenario for a game running uh like

00:03:39.760 --> 00:03:45.760
absolute worst case scenario it won't get this hot it won't get this loud in

00:03:43.280 --> 00:03:48.720
any sort of real game and this this only if you set it manually but I'm going to

00:03:47.080 --> 00:03:53.300
go ahead and turn it up to 100% just so you see

00:03:56.519 --> 00:04:03.480
it there you go okay moving on and

00:04:00.840 --> 00:04:10.120
finally for comparison we have the GTX 480 which is uh in some ways the Top Dog

00:04:07.200 --> 00:04:15.120
in terms of uh of noise generation due to the power and size of the GPU inside

00:04:13.120 --> 00:04:18.880
it so you can see our idle temperatures are a little bit higher than the other

00:04:17.320 --> 00:04:24.639
two cards that we were looking at at about 50° my room temps just for your

00:04:21.720 --> 00:04:30.440
reference are around the same they're 23 1/ 12° okay and then in terms of fan

00:04:28.600 --> 00:04:34.759
noise you can see that Fan's barely spinning I

00:04:32.199 --> 00:04:39.240
mean look at this it's not going very fast at all um this is quite a quiet

00:04:37.280 --> 00:04:45.800
card at idle but it's a bit of a different story underload so our gtx480

00:04:42.360 --> 00:04:48.000
peaked at around just over 90° under

00:04:45.800 --> 00:04:52.320
load can see here in fermar I want to stress again uh that not only for the

00:04:50.160 --> 00:04:57.560
gtx480 but for the other cards that we're looking at here that furmark

00:04:54.639 --> 00:05:03.160
represents an unrealistic gaming load it's mostly a tool for uh finding out

00:05:00.039 --> 00:05:05.080
the absolute Max temps and uh making

00:05:03.160 --> 00:05:08.400
sure that your card is 100% stable with an overclock

00:05:08.680 --> 00:05:15.039
so there's your reference point for listening to it and just for fun I'm

00:05:12.880 --> 00:05:20.160
going to turn this one up to 100% if you really want

00:05:16.360 --> 00:05:20.160
to blow your ears

00:05:21.639 --> 00:05:28.039
off quite quite loud at that particular

00:05:26.000 --> 00:05:33.840
setting so go ahead and put it back to Auto I mean bear in mind the G x480 does

00:05:30.319 --> 00:05:38.240
ramp up to about 80% fan speed um under

00:05:33.840 --> 00:05:38.240
under an intense load like this anyhow
