so today I'll be doing a quick unboxing of a new fan from Noctua this is the NFP 14 FLX now what the FLX suffix denotes is that it is a flexible design so that means that the flx fan has three different speed settings which are dududududu 1200 900 and 750 rpm and it achieves this through a few different adapters that are included with it other key features of this 140 millimeter fan are the impeller with vortex control launches and will show you those in a minute the metal reinforcements which allow the bla-bla-bla ultimate manufacturing precision high durability and vibration free running as well as a round frame now the round frame of this fan is what makes it so special and we'll get to more about that in a minute this has their updated drive bearing it has the ssl bearing with the smooth communication drive to ensure superb running of smoothing by eliminating torque variations and switching noises etc etc basically it's a fan but what makes it special is what we are about to get to here in just a moment so let's have a look at the accessories that are included with the NFP 14 FLX and first we have four rubber fan mounting grommets so rather than using screws which can transfer vibration directly to the case not to a fans use these little rubber mounting grommets these are quite common but they're only really included with higher end fans or you have to buy them separately next we have two low noise adapters so one is the low noise adapter and one is the ultra-low noise adapter so all you do is plug these in inline with the fan and they will make it run at a slower rpm next we have four metal mounting screws you can't always use those rubber grommets and sometimes good old fashioned mounting screws or what works best and then we have AA adapters so these are 120 millimeter to 140 millimeter adapter but wait - you said this was a 140 millimeter fan well it is because of the round frame they're actually able to make this 140 millimeter fan compatible with 120 millimeter mounts you can see if you had a we're frame going around these holes you'd have substantially less room for the Fen so not to his engineers ingeniously decided to make it work this way so all you have to do is attach the little metal bracket and you can see that that makes it a little bit wider a little bit further out so you can just attach it to a 140 millimeter hole or to a 120 millimeter hole very cool now the vortex control notches are what we'll talk about next here and let's just have a quick look at the fan here so you can see that they're offset we've got two notches here at the edge of the blade we have two notches here at the middle of the blade and two notches here closer to the center of the fan now what that means is that the way these disrupt the airflow is supposed to be more even overall because they're offset this way versus having all of the blades shaped exactly the same way Dokdo has been doing this on all of their fans for quite a while now and obviously they're very very well regarded fans because people paying very good money for not to a fans now another thing they've got called out here is the metal reinforced SSO bearing shell and magnet so that's kind of cool I suppose ok it comes with a sleeved three pin connector and the last accessory is probably something I should have mentioned before and it is a three pin two molex connector so you can power this thing any way you want you can power it at any speed you want and you can mount it any way you want thank you for checking out my unboxing and product overview of the Noctua NF P 14 ethyl X okay that wasn't really the end I've reboxed the fan already but what I noticed when I was Reebok Singh it is this little tab right here in huge boldface type so that I couldn't possibly miss it says open and we can actually open up this this merchandising thing on the back of the fan so we can find out exactly how the vortex control Naja's work because my explanation was just terrible okay so standard trailing edges can produce rotating pressure fields and vertices that cause audible noise at distinct frequencies this unhhhh this undesired tonal noise is much more annoying than noise that's spread over a broad frequency range so that is what the vortex control notches do they make it split into several smaller vortices and the noise is spread over a wider to frequencies and is therefore much less perceptible so there you go thank you for checking out my unboxing and my little add-on about the nf p14 FLX
