1
00:00:00,080 --> 00:00:06,680
for this video I will be testing

2
00:00:03,080 --> 00:00:11,880
the temperatures and Acoustics of the

3
00:00:06,680 --> 00:00:14,240
GTX 550 TI I'll be testing the Cyclone 2

4
00:00:11,880 --> 00:00:19,359
edition of the card against the reference NVIDIA designed edition of the

5
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

6
00:00:23,840 --> 00:00:30,279
maximum temperature ignore this is

7
00:00:27,000 --> 00:00:32,120
actually 75° and it looks like it takes

8
00:00:30,279 --> 00:00:38,879
us about 1,950 RPM or about 49% fan speed in

9
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

10
00:00:41,360 --> 00:00:47,399
have a listen and then I'm going to switch to

11
00:00:45,200 --> 00:00:55,320
the Cyclone 2 and see how much MSI's cooler improves The Thermals and noise

12
00:00:50,719 --> 00:00:55,320
characteristics of this video card

13
00:01:03,160 --> 00:01:10,360
well it looks like this is where we settle for the Cyclone 2

14
00:01:06,640 --> 00:01:13,520
cooler the max temperature is around

15
00:01:10,360 --> 00:01:16,880
63° so that makes it a good 10 plus de

16
00:01:13,520 --> 00:01:19,520
cooler than the reference design however

17
00:01:16,880 --> 00:01:24,600
it is louder at these settings than the reference cooler was so we're actually

18
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

19
00:01:28,720 --> 00:01:33,759
around 3,000 RP M so to give us that GPU

20
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

21
00:01:36,840 --> 00:01:43,079
done is they have actually set a more aggressive fan profile than NVIDIA had

22
00:01:41,240 --> 00:01:47,600
set on their reference card through the BIOS now one of the other things to note

23
00:01:45,240 --> 00:01:51,280
about these two cards is that besides the GPU temperatures you can see right

24
00:01:49,680 --> 00:01:57,840
here the mosfets do not have any additional cooling on them right in

25
00:01:53,759 --> 00:02:01,600
there whereas on the MSI card there's

26
00:01:57,840 --> 00:02:05,399
actually a metal Heat sink covering the

27
00:02:01,600 --> 00:02:06,880
vrms now that is very hot to the touch

28
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

29
00:02:09,479 --> 00:02:16,920
has even passive cooling on the vrms and then incidental air flow as well versus

30
00:02:14,519 --> 00:02:22,040
one that is only counting on incidental air flow from the fan to cool the vrms

31
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

32
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

33
00:02:28,040 --> 00:02:34,840
as the stock fan and see what kind of temperatures we get with a similar uh

34
00:02:32,920 --> 00:02:38,959
speed similar fan speed and similar noise profile so I actually got a far

35
00:02:37,160 --> 00:02:45,680
more desirable result than I had expected if we relax our GPU uh fan just

36
00:02:43,879 --> 00:02:50,599
by manually setting the speed so I've set it to

37
00:02:46,879 --> 00:02:55,640
45% um and that is around 1500 RPM we

38
00:02:50,599 --> 00:02:58,360
get 75° load temperatures in furmark

39
00:02:55,640 --> 00:03:04,879
and I mean so turning off the CPU fan here

40
00:03:01,560 --> 00:03:06,760
that gives us an almost silent

41
00:03:04,879 --> 00:03:11,640
experience compared to the reference cooler at the same temperature so the

42
00:03:09,319 --> 00:03:15,799
Cyclone 2 definitely does a better job than the reference cooler whether we're

43
00:03:13,120 --> 00:03:21,440
looking at silent performance or whether we're looking at sheer performance when

44
00:03:18,400 --> 00:03:22,840
you go to the max to see what it can do

45
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
