as you guys probably know I'm a huge fan of not too a fan so I'm super excited to check out the NFPA 14 FLX now as you know we've got a wide variety of different 120 millimeter cooling fans available from Noctua including their f-series and their p series which are optimized for radiators and heat sinks because they're very pressure optimized with the f-series the f12 actually having a directed cyclone of air coming away from the exhaust side of it now this doesn't have that functionality but this is a 140 millimeter version of what would be very similar to a p12 fan but with some additional technology so if you come in here and have a look at the actual features that are available on it we've got a square 140 millimeter frame this makes it ideal for case in Riyadh yes well you can see nakta web puts right here what it's for case and radiator cooling flow acceleration channels AAO frames depth Inlet design inner surface microstructure so integrated Eddy vibration pad smooth commutation Drive - basically what knocked was trying to say is their drives are engineered to the point of it being kind of obsessive so come in here and have a look at the fan itself and the accessories so unlike the 120 millimeter fans the 140 male fans come with not only a low noise adapter low noise adapter right there which I've down volts the fan to seven volts but also an ultra hold on a second okay well one of these is ultra-low noise one of them is low noise so one of them seven volts and one of them is 5 volts also comes with a molex to 3 pin adapter very nicely sleeve all of them right up to the connector so you're not going to see any unsightly colored wires we've also got extension cables did this is fantastic tape just a simple three pin extension cable mounting screws although usually you won't use those you'll use the rubber isolating anti vibration mounts I mean you can though because you've got more anti vibration mounts here the only problem with using the metal screws is because they have to drive into hard plastic and they will transfer some vibration to the case that way even with these rubber isolators so if you use these rubber isolators up against the case with these rubber Isolators bridging the hard plastic with the hard metal of the case itself then you've got no room for vibration to be transferred from the fan to the chassis when it's spinning not to say that not to a fans actually create a whole ton of vibration when they're spinning because they really don't the fans all come with short cables love this because it means that no matter where you install them I mean really in a case is only so big usually where you install it there's going to be a fan header somewhere nearby if there isn't they've included the extension that you need to run it wherever it needs to go that makes it more like a normal fan wire length love this - check this out this is a newer feature that they've started adding to their fans see these right here I couldn't figure out what they were for at first I thought they were just for sort of mounting the the rubber noise Isolators then what I realized is these are probably for cable management check this out so whenever you you know when you wrap a wire around the outside of a fan maybe they're not for that but whatever you can use them for that all you got to do is put them under these little rubber pieces and they will generally stay there very very cool stuff like you know when you take a fan and you mount it kind of like here at the back your chassis then you want to wrap it here down to here and then run it to a little bit awesome for that so I want you have a closer look at these rubber Isolators you can remove them if you want you don't have to keep them on you know say in the odd case that it causes some kind of a compatibility issue with your case or your cooler or anything like that you don't have to worry about it so let's have a look at some of the technologies that Noctua built into the fan number one is the six year warranty um so basically what they're saying is a hundred and fifty thousand hours or something like that is the mean time between failure for this thing and yeah there you go mean time between failure of greater than 150 thousand hours so they're pretty much saying yeah it's not going to die but if it does we'll deal with it without adapters it runs at 1200 rpm with an adapter this is the wrong fan with an adapter this one also runs at 1200 rpm but low noise adapters at 1050 ultra-low noise at 900 rpm so at 900 rpm this thing will be darn near silent alright technology-wise these guys right here these stepped inlets apparently reduced the amount of noise that is here we go stepped Inlet design step down let designers advanced aerodynamic design to blah blah blah blah first with the f12 the f12 was one of the most advanced fans ever by adding turbulence to the influx facility it's the transition from laminar to turbulent flow so similar to the dimpled structure of the golf ball leads to better flow attachment to the frame which allows the impeller to suck in more air and helps improve overall air efficiency we also use a very advanced bearing that is completely sealed so you won't get any micro dust inside they use flow accelerator channels on the blades themselves which is youth game there's lots of complicated stuff here generally speaking I am NOT an aerodynamic engineer I think you guys know this you've watched enough of my videos to know that that's not the case what I do know is that these fans are extremely well regarded even by those who have very advanced advanced equipment for testing fans I know this because I spent some time using their equipment testing Noctua fans and they were just like yeah they're really good sense they're just really good I do know that they last over the long term I've been using Noctua fans for a very long time on some of my quiet optimized systems and what I also know is that they're darn silent now guys there's more to it than just the RPM the CFM and the static pressure and the decibel ratings there's more to it than that there's how gracefully does it undervolt so some fans yes you can undervolt them but they start to develop a grind or a tic that doesn't necessarily get picked up by a decimeter so yeah you know it's there's an audible noise but it's more about how annoying is that noise not to a fans don't make annoying noises they you know sure maybe they look kind of distinctive but that's their branding you can always tell a knock to a fan when you see it so this guy right here perfect for radiators perfect for heat sinks oh yeah why is it perfect for radiators good question because knock twat has 140 and 150 millimeter fans that use a round frame which is not good for radiators because you'll lose the seal around the edges and in the corners like that which causes it to be less efficient this way the fan gets to go right up against this is 120ml Adam just using it for illustration purposes gets to go right up against it and causes a seal so that pressure optimized design actually gets to push air through the fins of the rad or the heatsink rather than worrying about it spilling around the edges you can see an example of where this wouldn't matter in this computer right here come on in closer because here we're going to have leaks around the edges no matter what so as long as we have reasonably good directed airflow through the fins we're going to be fine so you could use something like they're a 15 instead of they're a 14 it wouldn't be necessary to have that square shaped fan arrangement so let's just make sure we don't miss any of the other technologies that include so we got the flow acceleration chance with the advanced acoustic optimization frame stepped in in their surface microstructures so these flow separation from the suction sides which produce an reduced blade passing noise and improved air flow and pressure efficiency the anti-vibration pads we covered running smoothness by eliminating torque variations and switching noises this is actually something that's that's really good to know about so guys the circuitry and the design of the of the fan motor as well as the PWM are actually these aren't PWM fans but they do have pwn fans these guys are makes a huge difference in using third-party fan controllers on fans so the more optimized it is and the more of all the higher quality of the components that are used the less likely you are to develop any sort of weird vibrations ticking or whining noises hey 3 speeds ultra-low power consumption and six-year warranty metal bearing shell so plus the highest possible degree of manufacturing precision minimum tolerance excellent long serviceability CNC milled bearing shell made entirely from rest okay so there you go quality fans yeah they're expensive but you get what you pay for thanks guys for checking
