excellent hello everyone and welcome back to Pauls hardware today I have a fan video for all my fans out there it's gonna be fantastic okay so these are 120 millimeter gentle typhoon fans and they used to be available in the US as scythe gentle typhoon fans but sigh the USA has closed its doors so they're a bit harder to come by these days they are designed in Japan by night ech servo and I chose these because they are optimized for static pressure and quiet operation this series is available in five hundred eight hundred eleven fifty fourteen fifty and eighteen fifty RPM versions and this one is the 1,850 RPM variant the box gives you all the info you could want this is a 12-volt van with an operational range of five to thirteen point two volts twenty eight decibel noise level and that is at full RPM so running it slower keeps things much quieter 58.3 CFM airflow 200 gram weight which is pretty heavy for a fan and a MTBF of one hundred thousand hours at 35 c which is a very long lifespan and that's thanks to the double ball bearings in the large central hub also a 2 year warranty when it's sold outside of japan as it says here on the top of the box ok so the box doesn't tell you everything they did forget static pressure but it is listed on their website as 2.9 millimeters of h2o and who knows why they don't slap that impressive number on the box too but there you go for accessories you get four mounting screws and a three pin fan to 4-pin molex adapter with a tachometer lead for monitoring the RPMs the fan itself is very utilitarian it's got a simple but sturdy black plastic frame unfortunately no padding on the mounting points so I might consider some rubber washers the blade assembly is gray and has a very large central hub for the double ball bearing motor as well as nine blades with a very forward swept looking design the version I got from frozen CPU has a black braided 3 pin fan cable with a white plug and it's only about a foot or 31 centimeters long so an extension might be necessary depending where you're placing it in your case next up I'm going to plug this in with a speed regulator and give you guys a sound test at a few different speed levels alright guys so here's my sound test and I was actually kind of excited I get this digital sound level meter here to do some sound testing with but as you can see I have a position very close to the fan right now this is just about five inches away and the reason I did this is because it's the only way you can get this sound meter to pick up this starts at 40 decibel hey waiting and it's really the fans quieter than that I'll be quiet for a second so you can see the the readout on there but you'll notice it really it's not showing much of anything as you can see it's just popping up here and there maybe getting a little bit over 40 40 41 decibels from that reading and again that's a 5 inches away and the actual rating from the box they're going to have further away than that so all I'm really going to have for the rest of these ties because this is full-speed I should mention that right up front this is full speed test at 1850 rpms it's fluctuating between about 1825 and 1850 and I'm just going to go ahead and put the sound meter away for the rest of these and just use the mic and let you guys listen to what it sounds like at the other speeds and that's going to wrap it up for the fan speed test as you can hear pretty much once you get it below about 80% RPMs you essentially can't hear this at all unless you have your ear right up against it and that's going to do it for this video guys once again this has been the gentle typhoons currently distributed by 9x servo if you're interested I post a link down into the in the video description where I actually purchase these so you guys can check it out don't forget to hit the like button while you're down there don't forget to subscribe to my youtube channel and keep your eyes peeled because I will be using these fans in my personal system and when I do my personal system kind of rebuild I will be doing a video of that and showing it to you on my channel so that's why you should subscribe of course but that's all for this one have a fantastic day and we'll see you next time
