well I wanted to take some time to compare the reference cooler for the GTX
560 and I realize I'm holding entirely the wrong prop right now but the
reference cooler for the GTX 560 so this is a flowerstyle heat pipe cooler so you
can see if I I guess if I spin that you might be able to see a little bit better
you can see it looks kind of like a stock Intel LGA 1155 heat sink and then
there's three heat pipes that come out of the top you can you see in there okay
what if I turn like this can you see the heat pipes no okay how about now can you
see the heat pipes through the
top really you can see the heat pipes okay
one two three heat pipes like that so those are spreading out into a uh like
fin Arrangement on either side so it's actually kind of like the MSI Cyclone
cooler in design but it's covered with a shroud now some of the exhaust is going
to come out here some of it's going to come out here some of it's going to come
out here and some of it's going to come out here so while it does have a rear
exhaust vent for all intents and purposes we can consider this a sort of
70 to 80% internal exhaust card now I
wanted to compare that to the MSI GTX
560 twin frozer 2 now this is not that
card this is a GTX 460 Hawk the twin frozer 2 card is actually on the test
bench right now preparing for my idle temperature measurement but I'm going to
compare both temper temp and noise levels of the twin frozer 2 heat sink
which looks like this now this is an almost entirely internal exhaust heat
sink as well you can see we're going to get some incidental air flow from this
fan coming out here but other than that there's a lot ex of exhaust coming right
through the card here in the gaps right through here there's going to be some
going out this way uh the heat pipes including uh two super pipes that is
thicker than standard heat pipes and two normal ones so there are four total heat
pipes are part of the overall design it
does use a dense fin arrangement with dual fans in order to achieve what MSI
claims is up to 20° better cooling under load than a stock cooler
now it's become a little bit challenging with recent gpus to measure maximum load
so instead of using furmark which was my traditional favorite um because of the
way they've locked them down to actually underperform in furmark so that you
don't blow your GPU by benchmarking furmark all day which I can kind of
understand what I'm actually going to do is I'm going to Loop the heaven
Benchmark and then just find the highest
temperature recorded during the entire thing this will be lower than normal so
probably the Delta will be lower than we'd normally see but I guess it'll give
us a more realistic look at what kind of
noise and what kind of temperatures we're going to get with these cards in a
gaming scenario so right now I'll show you guys my testing methodology I've got
the GTX 560 on an Open Bench bear in mind Open Bench is going to be up to 5
to even 10° cooler than what you're going to see in a closed case either
that or the fan will ramp up more so it will also be in some ways quieter now
I've got my ambient temperature here which is about 23 Dees and I have a
temperature probe right here in front of the fan intake So based on a 23° intake
temperature and a 27° idle temperature
on my card I will call that a Delta of
4° for my GTX 560 so I'm going to do some
load temps and I'm going to do some testing on the reference design and then
I'll come back and do a conclusion for you guys that to stress the card as much
as possible I am running the tessellation on Extreme as well as 8xaa
and no it's not counterfeit I just changed my Hardware all the time AA uh
8x8 and 16x AF otherwise looks like this
now in terms of temperatures uh hold on I'm going to turn my sensor back on so
the room temps have gone up a little bit because I did have the doors closed so
we're at 26° in the room now and the maximum and I'm going to take the
absolute Peak maximum we saw during the heaven Benchmark was
54° so that was the highest that was
seen okay so then that means uh 54 - 26
is I'm not very good at Mental Math so I'll be recording that on a graph and
then I'll show you guys the reference cooler in a moment okay so just getting
an idle temperature reading from my reference card so we're going to call
that 23° ambient and we'll call
that an in complete inability of my camera to focus on anything well I'll
tell you what it says then it says 28 so there is the reference card on the bench
and there is another attempt to focus come on come on come on come on come on yeah you can kind of see that 28 so
that's a Delta of only about five ° so
back with the load results so we can see
here on the graph what our Max temperatures were while running the
heaven Benchmark we peaked at around 70°
so that is a Delta of uh actually we
here I'll do the math
um okay because our room temperature is now
23 actually it was 24 a moment ago but I opened the door so we're going to go
with 24 uh I way here is the data I'm
not going to bother graphing this for you guys I'm sorry so with the hawk we
had a 4° Delta from the room temperature
uh up to the temperature of the GPU at idle so a 5 Dee Delta on the reference
card but then when we look at the load temperatures it is almost as advertised
on the MSI box almost a 20° difference
between the four 560 twin frozer 2 and
the 560 reference card so you can see
that MSI does advertise 20° C cooler now
uh if we were running a more extreme scenario we probably might see 20° as a
worst case scenario something else to bear in mind is this is an OC Edition
card so naturally the twin frozer 2 card
will run a little bit hotter so if we clocked it down to the same speeds as
the reference card we might actually see even better temperatures so thank you
for checking out my video of the GeForce GT TX 560 TI thermals and Acoustics as
well as the comparison between the reference card and the twin frozer 2
Edition card from MSI don't forget to subscribe to Linus techtips for more
unboxings reviews and other computer
videos so this is my noise reading for the gtx560 ti twin frozer 2 going to go
about 6 in from the fan and let you guys take a little listen and then I'm going
to cut in the reference
cooler and here's my load test on the twin frozer 2 so I'm just going to move
my normal distance from the
card and I'll cut in with the reference
cooler
