hey everyone we're doing a subjective a noise test today so in our review which is already live of the RX 480 there is a coverage of the noise output of this blower fan compared against other fans we've got the decibel readings there but it doesn't always really help to just look at decimal numbers so I wanted to do this separate video will install this thing and the plan is to demonstrate just how loud 100% is when you have the fan at 100% speed which you should basically never have it there and and how generally reasonable the auto and fifty percent settings are which are more or less the same before getting to that this coverage is brought to you by Origin PC and their new origin at Kronos small form-factor PC which is customizable upgradeable and now shipping with the RX 484 high-end that home theater and via our gaming so there's the RX 4 80 installed in the bench a single 6 pin power and now we're going to use the AMD driver software called wot man to manage the fan speed settings ok so we've got the card installed and we're at the beautiful resolution of whatever this is 1024 or something like that but installing the drivers here keep in mind that you want to get rid of the trash software gaming evolved and once we've got these installed we can go ahead and manage the fan speed settings in wot man alright ok is it working yes ok so here's what we've got for the test the plan here is I've got a decibel meter we already used this from a tripod mounted position it did not move it was pointed out the card you can read about the test methodology how far it was sensitivity things like that in our test methodology for the review of the RX 480 so that was covered and then we've also got control of the fan through software and I'm gonna be putting that through against a 1070 so you can compare the two and we'll have the decibel charts on screen at some point for you if you want to see that just pure decibels but let's go and do the subjective look at how it sounds and we have to navigate this awful interface to get there there's about five clicks too many to get to fan speed control so once you arrive on this screen it will begin login and showing sort of some of the performance metrics this is our state step in for some of the other stuff but what we want is just the fan for today so this can't be done through afterburner as of yet because this is before the card was officially shipped so there's no support yet and here's the fan so we've got our rpm here if we switch this to manual control you'll see these bars appear and the maximum speed of this fan is 5200 rpm so that means our our 50% speed will be 2600 rpm so let's go for the most extreme thing here and just tell it to run at 5200 rpm I haven't applied this yet once this starts here's another thing to keep in mind so we have a sound recorder we use that for capturing all the audio for our videos and that recorder we're attaching a stereo XY microphone to you were mounting it to a tripod and pointing that mic at this card at the fan it'll be positioned 20 inches away as our decibel meter was also positioned that distance during our decibel noise level collection and putting the mic there will give you an idea of what this sounds like we'll cut to that noise separately though so here's here's what we're gonna apply this setting and there goes so it's much louder as you can hear the decibel levels for this first of all this is a blower fan that means all the air is pulled in it gets pushed out the back you feel it coming out here and there's actually cut out in the back of the cart as well where I believe it holds some air in but the decibel level is at 100% speed it's 65 point 6 decibels and that compares against the r9 290x reference which was 69 point Ford as well so this you can hear I'm raising my voice to talk over this this is what 60 pit five points accessible sounds like and then we'll just cut right here and show you without me talking what it sounds like compared against 50% and idle so another note I've got this liquid cooler set to silent the only noise it's really making it's coming from the pump can't even hear right now over this fan these are the 120 millimeter case fans you'll notice they are all unplugged and not doing anything and that is because we're not doing thermal tests for doing noise test so don't want the extra noise so all the noise come from the power supply and the CPU cooler pumped for the most part and now the video card which is overwhelming all of it decibel levels when you're reading decibel charts it's logarithmic so you can't do calculations just a normal subtraction to get a delta it's a logarithmic formula which we show on the site if you're curious about that now if you want to see how hard this thing is pushing air I suppose there's a few different tests you can do you can kind of do one of these so that's a pretty good and let's bring it back here you can see it's flat or whatever you want to call it vertical let's do that that's a good amount of air coming out of there of course there's also the classic photo shoot so here's our there's our options that is 100% speed so let's turn this down to 50% speed for 2600 I don't think I have to change both these values so we're gonna do it anyway 2600 apply okay all right so now at 50% we are hitting 40 2.8 decibels when we get this chart out I will show it on the screen as well so forty two point eight decibels at 50 percent versus 65 0.6 decibels at a hundred percent and down at the auto setting which is going to be more closely resembling what you get in real world performance the auto setting is collected after five minutes of real-world gaming and it's pretty abusive gaming so then we end up with this thirty nine point four decibel metric and that is against idle of thirty seven point three so there's really no no noticeable increase in in decibel levels for the video card between idle and auto when you're gaming now one thing here all of these numbers if you notice the top of the charts has system noise levels that's because this isn't just a noise level of only the fan it's a noise level of the entire system we don't have a good way to measure just the thin so you have to factor in here the the noise of power supply and other components which is very low these are pretty quiet components for a reason but it's not zero so that doesn't mean there's some additive logarithmic additive noise from these other components and one other item to note is when looking at noise levels you also have to subtract out the room noise if it's known we measure the room noise before every test its subtracted using that formula and then we end up with these values so these are already Delta values versus the environment which is about 25 decibels when there's nothing on whatsoever including a/c or HVAC so that's the fan at 50% and at a hundred percent let's bring it down here I think the lowest value is probably 1200 it will it should should force me to not go below there okay so 10:40 I've never seen it actually that low if we put it on auto apply I think it'll go up to 12 okay so 1042 2200 so this is noticeably quieter to me I don't know really how it picks up on on the mic we're using right now but we will cut in some audio standalone of this just so you can hear it so that's the idle noise levels the next thing I'm going to do is put this in this is the reference or founders Edition 1070 we've already published all of our noise charts for this in the 1070 review and in the our X 480 review which again linked in the description down below so we'll look at this again this time it will be a subjective test which there's objective measurements there's decibel measurements as you've already seen but the subjective part will help you actually compare what those decibel numbers mean in the real world since it's kind of hard to understand otherwise I know why they changed their font how does that meeting go alright create a new version of precision like I can't even close it what bring the camera over here EVGA please make the ex work okay all right Thank You Jacob okay all we're doing is changing the fan speed same thing here let's jump straight to a hundred percent speed on the GTX 970 founders edition card here we go takes a little longer to ramp into it but not quite as loud as the Andes car antique art at 100% fan speed and objectively we have the numbers for you here this is again tested with the proper noise setup not how we have it right now for demonstration purposes so at 100% speed the founders edition card on this chart is going to be the dark blue line that's labeled GT X 1080 and 1070 that type 57.2 decibels for 100% speed versus 60 5.6 for Andes now Andes runs faster it's at 5200 rpm and this fan is running at so and these fan runs at 5200 rpm and this one runs at about 4000 more or less so it is slower obviously that's why it's a bit quieter they both are not great at cooling as you've seen on our reviews of both these devices as always a Ivy Partners do a much better job with cooling in general as a kind of general sweeping rule but that's what we got for 100% speed let's compare that to 50 and see the noise difference here it's a considerably quieter of course 50 again is about what you'd be hearing in most gaming scenarios charge do not really ramp up to 100% speed in the real world and that's for a lot of reasons but you can configure it to 100% speed if you needed it for something like mining or whatever so 50 percent speed we're at 40 1.9 decibels and these 42.8 basically the same and then the auto setting we've got as well logged as 47 friend Vidya and 39.4 on the other card so that pretty much wraps up the noise comparison they are more or less the same at reasonable settings it's only when you push to a hundred percent that this thing becomes unbearably loud but the use cases where a fan is that a hundred percent are very limited because they are normally they use a custom fan profile that will generally prohibit ever reaching that speed you'll start seeing system shutdowns and things like that from thermals if it doesn't get there if it really needs to but for gaming you're never gonna be in that scenario so that's our quick subjective fan noise comparison thing checks review for the RX 480 and if you're
