hello everyone and welcome to today's video this is kind of an impromptu off-the-cuff one because I wasn't really planning on doing a video today but then I got a package in the mail and I was like I want to do a quick unboxing of these because what I got is these new fractal design venturi HP 12 fans I got six of them total you heard him 20 millimeters I know her you broke in one of the cardinal rules of unboxing because I've already unboxed one of them but that's okay because I have six of these so I can unbox one of the other ones for you guys so go over some of the specs of these fans some of the specs of the other fans in this series and why not also plug one end into a quick hands-on test let's begin this unboxing in the traditional fashion by taking a closer look at the retail box this is the venturi HP - 12 high performance computer fan this is a hundred and twenty millimeter version here and fractal has actually released four new fans in the event arees series this is HP 12 which is a high-pressure and this is a PWM fan there's also an H f12 which is 120 millimeter or 12 centimeter high flow fan which is more optimized for air flow so get to HP's if you want to use these with a radiator which is I'm going to do what I'm gonna be doing gonna be using these in the arctic panther back there and get the hf series if you want more airflow for like intakes and exhausts on the computer that aren't gonna be right up against a radiator or something else that requires high pressure okay apart from that on the back we have information about the fans such as dimensions already told you is 120 millimeter it's got a four pin fan header because it is a PWM capable fan and I do appreciate PWM fans because they can ramp themselves down although bear in mind you can't ramp them down infinitely that's why I'm using these fans in the arctic panther I actually have some of the ek Vardar the Furious of our dars which are 3000 rpms and there's nothing wrong with those fans inherently however they are quite loud because they're 3,000 rpm fans I was going to hit up ek and get some replacements for those and get the lower rpm versions but then fractal came out with these and I was like well let me give these a shot so that's why I'm using these so not a slight against TK in any sense anyway it's a fluid Dino that's another reason why I really like these fans I am a big fan haha oh fluid dynamic bearings I find them to be have a long lifespan and to stay quite quiet for the most part three year warranty 150,000 our mean time between failure and these are 12 volt fans at 0.2 amps so bear that in mind if you're gonna try to stack a bunch of these on top of each other or something like that on the right side over here we have a couple different sets of performance metrics because these are PWM so you have full speed at 1,800 rpms or you can use the PWM function to lower their RPMs all the way down to 400 if you want the least amount of noise possible so at 1,800 rpms they move about 60 1.4 cubic feet per minute of air and they have 2.3 millimeters of h2o static pressure which is pretty nice at a 31 point 7 DB noise level for 400 rpm rotational speed here at 15 point 4 CFM your static pressure goes down to 0.45 but your noise level also goes down to pretty much inaudible all right what else what else look it's a fan with a flappy flappy flap that opens sets that's rare I don't see those so look again you got a peekaboo window in here and then you have a little layout of the actual fluid dynamic bearing and I thought that was kind of interesting you guys want to read this I bet you do the inner surface of a true f DB bearing is covered with two sections of small herringbone grooves when the shaft rotates which is quite common especially with products that josh is behind oil is pushed along those grooves creating two pressurized oil films between the shaft and the bearing shell this stabilizes the rotor resulting in a longer product life so that's kind of their fancy fluid dynamic bearing design also it's got a counter pull magnet in there so when pushing the air forwards the blades of a fan are pushed back by an equal force that's pretty basic physics by adding a magnet that pulls the shaft in the opposite direction the stress on the bearing can be reduced this leads to more silent operation and a longer life span so just to summarize this little section according to fractal you need to pull the shaft in the opposite direction and then go ahead and rotate the shaft and that leads to a nice quiet fan they also have some optimized design here for their optimised blade and statwhore design that's interesting the noise created when the blades passed the stat or struts though the struts okay so the things that kind of hold the center in place these things that's what those are okay so the noise created when the blades passed the status struts is significantly reduced by three features aerodynamically shaped struts including the wire strut tone defusing notches on the blade edges and the very wide angle between the stutter struts and the trailing edges of the blades that make sense to you guys sure it does and then finally I'm doing this completely out of order but trip wire technology so based on technology commonly used on airplane wings the trip wire introduces a layer of turbulent air near the leading edge of the fan blade that way sudden boundary layer separation can be avoided giving a smaller turbulent layer at the end of the fan blade this reduces noise and improves fan efficiency now what the product out of the box you can see fractals gone with a fairly unique design here really something that I haven't seen before when it comes to case fans at oh I'm sorry this is the venturi that's that's made for aerating one easy easy mistake to make let's go ahead and get this out of the box though so I'll take a look at the accessories that are included here and fractal has dropped in a few extra goodies here aside from the fan itself which I found a nice and I will also point out to some of the accessories that come not just with this high-pressure version but also which with the hf version so there's the fan with the HP versions HP 12 or HP 14 if you're going 120 140 millimeters you get a PWM splitter and I think this is nice to have because often these are going to be used on radiators radiators are frequently two or three fans that are required and being able to split that off with the full 4 pin PWM capability is gonna be nice and that will help you allocate your fans to fan headers that might be in your case it also of course gets mounting screws typical black screw mounts fan fan screw mats fan mount screws yes and then of course the fan itself so taking a look at the center you might really might recognize this design just a little bit in fact I have its counterpart over here so let's bring that in here to take a look so this is 140 millimeter fan that I took out of the Defiant r5 and the model on this one is actually a little bit different this is the dynamic GP - 14 and you'll notice some of the different things I think this might still have the FDB bearing in there but you're not going to have like the rubber on the outside these are plastic on the outside you don't get the sleeved cable as well and these are three pin gives you voltage control not necessarily the four pin that the venturi HP - 12 gives you now a cool thing that they give you at the hundred and forty millimeter models that isn't included here because these are 120 is they actually give you removable replaceable rubber corners so these are rubber of course so when you screw these in the screw is not going to touch anything that's not rubber so that's pretty cool but again on 140 millimeter versions they actually give you some replacement corners they give you a hundred and five millimeter mounting space so you can actually mount the 140s on smaller fan mounts which is which is pretty cool what else do we have here of course the cable there we go nicely sleeved all in black this is another nice benefit as opposed to the Furious bars which have the red cable which I was gonna have to sleeve these I think I can leave as is because this is a decent sleeping job you can see some heat-shrink there but not terrible by any stretch and there of course is your four pin header at the end as well one other thing to mention since these are the HP versions and as I already showed you they come with a little splitter the hf versions the hf 12 and HF 14 are not PWM controllable they have three pin voltage controls so what they include with those to give you a bit more options for speed is they include some resistors some inline resistors that you can use to lower the RPMs on those too so whether you're getting the PWM versions or no you will still have some level of control over the actual fan speed and noise generated and now for a quick demo this is like completely unscientific and really just like anecdotal also if I sound further away now it's because I've actually flipped my microphone around so it's pointing forward so when I turn these fans on you will hopefully be able to hear them or maybe even not hear them I have two of the fans connected I'm not using PWM I'm using this little fan controller here and this only does three pin voltage control so I guess this is a voltage control test with the PWM fans I have it connected to a little molex AC adapter over there going in to control that and I just turned on and the fans are spinning I can hear nothing all right now voltage control still works with PWM fans I'm going to turn both of these all the way to max and I'm max yes this is 1800 rpms and they are gonna make a little bit of noise so again this is 100 percent speed this is full speed moving a little bit closer so you guys can hear maybe I'll focus too alright the mic right now is about like four inches three four inches from these fans so that's what you guys are hearing not too bad right again that's a hundred percent full speed so I'm gonna go ahead and turn it down at least to the lowest voltage wise that's metal the whole fan controller is able to do I'll wait for the car to drive by car still outside maybe you guys can hear the car more than the fans but um all right so here's them at low speed I can't confirm that this is 400 rpm but I'm guessing it's about that much this is as low as the voltage as metal faint controller would give them and here they're just they're just dead so and I'll let you guys listen for a second yes I can hear nothing I hear absolutely nothing okay one last quick test and that is to see if that's the lowest voltage provided to these since they are PWM and I'm not giving them PWM power there we go will they spin answer yes so cool even if you're not connecting these to a PWM controllable fan controller or motherboard header through the know that you can still get nice low rpms out of them but that's the benefit of PWM as you still can do voltage control as well and guys that is just am I gonna wrap it up so I hope you've enjoyed this little video my quick demonstration of the fractal design venturi HP 12 fans again there's a HP for high pressure 12 and 14 centimeter designs there's also the H F 12 and H F 14 which are high flow designed for air flow these I'm going to be installing in the arctic panther back there I have some work to do on that because I'm going to need to pull all of the radiators out don't worry it's not like a bad thing was already planning on doing that so not a huge deal and that video should be coming up soon I have a couple more build videos coming to but don't forget to subscribe to my channel don't forget to hit that like button go ahead and check out my store at startup pulsar red dot net for t-shirts and that kind of stuff and we'll see you all very very soon in the next video
