00:00:00.080 --> 00:00:06.680
for this video I will be testing

00:00:03.080 --> 00:00:11.880
the temperatures and Acoustics of the

00:00:06.680 --> 00:00:14.240
GTX 550 TI I'll be testing the Cyclone 2

00:00:11.880 --> 00:00:19.359
edition of the card against the reference NVIDIA designed edition of the

00:00:17.480 --> 00:00:27.000
card so the first one I have here on the bench is the reference card so our

00:00:23.840 --> 00:00:30.279
maximum temperature ignore this is

00:00:27.000 --> 00:00:32.120
actually 75° and it looks like it takes

00:00:30.279 --> 00:00:38.879
us about 1,950 RPM or about 49% fan speed in

00:00:36.440 --> 00:00:42.760
order to achieve that temperature so I'm going to get close and I'll let you guys

00:00:41.360 --> 00:00:47.399
have a listen and then I'm going to switch to

00:00:45.200 --> 00:00:55.320
the Cyclone 2 and see how much MSI's cooler improves The Thermals and noise

00:00:50.719 --> 00:00:55.320
characteristics of this video card

00:01:03.160 --> 00:01:10.360
well it looks like this is where we settle for the Cyclone 2

00:01:06.640 --> 00:01:13.520
cooler the max temperature is around

00:01:10.360 --> 00:01:16.880
63° so that makes it a good 10 plus de

00:01:13.520 --> 00:01:19.520
cooler than the reference design however

00:01:16.880 --> 00:01:24.600
it is louder at these settings than the reference cooler was so we're actually

00:01:21.680 --> 00:01:32.159
at a fan speed of about 71% well about 70% exactly 71% and that is a fan RPM of

00:01:28.720 --> 00:01:33.759
around 3,000 RP M so to give us that GPU

00:01:32.159 --> 00:01:38.439
temperature we are paying a bit of a price in terms of noise so what MSI has

00:01:36.840 --> 00:01:43.079
done is they have actually set a more aggressive fan profile than NVIDIA had

00:01:41.240 --> 00:01:47.600
set on their reference card through the BIOS now one of the other things to note

00:01:45.240 --> 00:01:51.280
about these two cards is that besides the GPU temperatures you can see right

00:01:49.680 --> 00:01:57.840
here the mosfets do not have any additional cooling on them right in

00:01:53.759 --> 00:02:01.600
there whereas on the MSI card there's

00:01:57.840 --> 00:02:05.399
actually a metal Heat sink covering the

00:02:01.600 --> 00:02:06.880
vrms now that is very hot to the touch

00:02:05.399 --> 00:02:12.239
and I got to say I would be more comfortable with a card that has ACT or

00:02:09.479 --> 00:02:16.920
has even passive cooling on the vrms and then incidental air flow as well versus

00:02:14.519 --> 00:02:22.040
one that is only counting on incidental air flow from the fan to cool the vrms

00:02:20.280 --> 00:02:25.879
now one thing I'm going to do before we finish this up and this is kind of a new

00:02:23.519 --> 00:02:29.959
thing is I'm going to tweak the fan on the Cyclone 2 to be around the same RPM

00:02:28.040 --> 00:02:34.840
as the stock fan and see what kind of temperatures we get with a similar uh

00:02:32.920 --> 00:02:38.959
speed similar fan speed and similar noise profile so I actually got a far

00:02:37.160 --> 00:02:45.680
more desirable result than I had expected if we relax our GPU uh fan just

00:02:43.879 --> 00:02:50.599
by manually setting the speed so I've set it to

00:02:46.879 --> 00:02:55.640
45% um and that is around 1500 RPM we

00:02:50.599 --> 00:02:58.360
get 75° load temperatures in furmark

00:02:55.640 --> 00:03:04.879
and I mean so turning off the CPU fan here

00:03:01.560 --> 00:03:06.760
that gives us an almost silent

00:03:04.879 --> 00:03:11.640
experience compared to the reference cooler at the same temperature so the

00:03:09.319 --> 00:03:15.799
Cyclone 2 definitely does a better job than the reference cooler whether we're

00:03:13.120 --> 00:03:21.440
looking at silent performance or whether we're looking at sheer performance when

00:03:18.400 --> 00:03:22.840
you go to the max to see what it can do

00:03:21.440 --> 00:03:26.959
so why don't we just see how loud it is at maximum volume just for fun and thank
