all right guys so I'm going to take a slightly different approach to my
temperature and Acoustics testing than I
normally do this is with the HD
6990 so what I'm going to do is instead of holding my camera here close to the
fan I'm actually going to hold it above
the card right here and the reason I'm
going to do that is because there's two things I'm going to compare it against
I'm going to compare it against a single GTX 5 80 and I'm going to compare it
against two GTX 580s in SLI so that'll
give us a comparison against a high
powerered single card as well as two high powered cards running in tandem so
here's our idle temperature reading which is 39 to
38° in this particular room all right so
we've got our load temperature for the radon 6990 and uh that is 8 2° and oh man you
guys can't see this at all can you focus focus focus focus come on focus on my
hand focus on the screen whatever you'll have to take my word for it 82° and 87°
on each of the gpus so I'm fairly certain that the 82° is on this GPU and
the 87° is on this GPU and I think the reason for that is that this Grill at
the back is more restrictive or uh at
yeah than this Grill at the front of the card because as soon as I go like this
this the cooler GPU starts to heat up to the same kind of temperatures as the
less cool GPU so uh that's something
maybe they uh if you installed an aftermarket less restrictive Grill on
your card you might have some success keeping down your GPU temperatures a
little bit all right so right now I'm running only one of the gpus uh at its
fan speed uh at its load fan speed so this is at
91° in furmark so this is the EVGA card
that's running because remember wind openg GL programs will not run in SLI
mode and for my two card Acoustics test
I'm just going to take both cards I'm going to turn them up to the same percentage fan speed manually because I
can't be bothered to run it and open our in full screen mode and change the exe
and all those little tricks so the fan speed's around 80% so I'm just going to
turn both fan speeds to 80% and take a
reading
and just for last guys here's 100% fan
speed on the 6990 although it never ramped up to this speed during my
testing so I'm going to be turning off auto in After Burner go away cat turning
off auto and after burner and watch the piece of paper on the wall when I click
apply okay bear in mind the card is here so it's about yay far away from the wall
okay oh watch the cat too this might be funny
see it's lifted away from the wall so in conclusion the Radeon 6990 is
pretty darn loud but it's also pretty darn powerful don't forget to subscribe
