0:00 for this video I will be testing
0:03 the temperatures and Acoustics of the
0:06 GTX 550 TI I'll be testing the Cyclone 2
0:11 edition of the card against the reference NVIDIA designed edition of the
0:17 card so the first one I have here on the bench is the reference card so our
0:23 maximum temperature ignore this is
0:27 actually 75° and it looks like it takes
0:30 us about 1,950 RPM or about 49% fan speed in
0:36 order to achieve that temperature so I'm going to get close and I'll let you guys
0:41 have a listen and then I'm going to switch to
0:45 the Cyclone 2 and see how much MSI's cooler improves The Thermals and noise
0:50 characteristics of this video card
1:03 well it looks like this is where we settle for the Cyclone 2
1:06 cooler the max temperature is around
1:10 63° so that makes it a good 10 plus de
1:13 cooler than the reference design however
1:16 it is louder at these settings than the reference cooler was so we're actually
1:21 at a fan speed of about 71% well about 70% exactly 71% and that is a fan RPM of
1:28 around 3,000 RP M so to give us that GPU
1:32 temperature we are paying a bit of a price in terms of noise so what MSI has
1:36 done is they have actually set a more aggressive fan profile than NVIDIA had
1:41 set on their reference card through the BIOS now one of the other things to note
1:45 about these two cards is that besides the GPU temperatures you can see right
1:49 here the mosfets do not have any additional cooling on them right in
1:53 there whereas on the MSI card there's
1:57 actually a metal Heat sink covering the
2:01 vrms now that is very hot to the touch
2:05 and I got to say I would be more comfortable with a card that has ACT or
2:09 has even passive cooling on the vrms and then incidental air flow as well versus
2:14 one that is only counting on incidental air flow from the fan to cool the vrms
2:20 now one thing I'm going to do before we finish this up and this is kind of a new
2:23 thing is I'm going to tweak the fan on the Cyclone 2 to be around the same RPM
2:28 as the stock fan and see what kind of temperatures we get with a similar uh
2:32 speed similar fan speed and similar noise profile so I actually got a far
2:37 more desirable result than I had expected if we relax our GPU uh fan just
2:43 by manually setting the speed so I've set it to
2:46 45% um and that is around 1500 RPM we
2:50 get 75° load temperatures in furmark
2:55 and I mean so turning off the CPU fan here
3:01 that gives us an almost silent
3:04 experience compared to the reference cooler at the same temperature so the
3:09 Cyclone 2 definitely does a better job than the reference cooler whether we're
3:13 looking at silent performance or whether we're looking at sheer performance when
3:18 you go to the max to see what it can do
3:21 so why don't we just see how loud it is at maximum volume just for fun and thank
