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