this is going to be a quick video on the temperatures and noise of the radon
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 1° then the
card temperatures will go up by exactly 1° 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° idle at a
2 2 and 1/2 uh 22 to 23° room temperature we're
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
over here watch the temperature Skyrocket just from the heat my hand's
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° 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 a little bit of fan normal fan sort of a grinding
noise uh within probably about 12 to 14 in but beyond that and especially inside
a closed case you will not hear this thing so 41° 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 furmark in extreme burn mode is going to yield an
83° 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 After Burner okay so you
can listen you can compare those two clips
against each other so it is uh 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 uh 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 gtx480 as well as the 5870 just so you got a reference
point here's the 5870 for my noise
comparison getting nice and close to the fan now the 5870 is a touch louder than
the 6870 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 just a sec uh no
the fan is exactly the same diameter for some reason there's a little bit more
wor 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° at least 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° 38° and then my room Temps
are around 22 23° 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° using the default fan profile remember with afterburner you
can always uh change profiles around if you want so you can see we're running at
about 44% on the fan speed and uh 87° on
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
mark is pretty much a worst case scenario for a game running uh 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 this only if you set it manually but I'm going to
go ahead and turn it up to 100% just so you see
it there you go okay moving on and
finally for comparison we have the GTX 480 which is uh in some ways the Top Dog
in terms of uh 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° my room temps just for your
reference are around the same they're 23 1/ 12° okay and then in terms of fan
noise you can see that Fan's barely spinning I
mean look at this it's not going very fast at all um this is quite a quiet
card at idle but it's a bit of a different story underload so our gtx480
peaked at around just over 90° under
load can see here in fermar I want to stress again uh that not only for the
gtx480 but for the other cards that we're looking at here that furmark
represents an unrealistic gaming load it's mostly a tool for uh finding out
the absolute Max temps and uh 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 100% 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 G x480 does
ramp up to about 80% fan speed um under
under an intense load like this anyhow
