120mm High Performance PWM Technology Fan - Translucent Blue (b-PWM 120 Blue 2ball)

This fan moves a lot of air. Hooked it up loose to a 3 pin mobo connection just for a little quick test and Speedfan reported 3771 RPMs and it was kickin some CFMs to blow your hair back. Not exactly quiet but not what I would call loud. Any fan running at that speed and moving that much air isn't going to be silent but I wouldn't say it was loud either. Pretty much what I would expect for decently made somewhat high speed fan. It does seem more geared towards airflow than static pressure so I don't know how well it would do with moving air through a filter or heatsink. But for a general case fan I don't know what more you could ask for. And the LEDs are nice and bright. When I get it in it's permanent spot it will be on a proper PWM terminal and should rarely if ever need to run at 100%, but nice to know it can really move some air if it has to. It will also be drawing air through a front case intake with a thin dust filter so we shall see if static pressure becomes an issue then. Also I am a big fan of dual ball bearings. I find it's sometimes a crap shoot with longevity between bearing types though from an purely intelectual standpoint I prefer mag-lev then dual ball and consider anything else disposable junk. But when sleeve or hydraulic bearing fans fail they generally go quietly and if you don't have an eye on your temps some component could fry itself. Ball bearing fans on the other hand will generally start chattering a bit to let you know there's a problem days or weeks before they get so bad they fail. So you're alerted to the situation, have time to order a new fan, and can keep using the PC in the mean time with no overheating. Anyway great fan, great price. Will post an update if anything unexpected comes up after it's running in it's permanent spot.

I used this with a Nexus 92mm to 120mm fan adapter for my AIO CPU radiator.My MSI motherboard heat sink was preventing me from installing the 120mm radiator fan for my AIO liquid cooler so as a last resort I decided to try an adapter with a smaller fan but after a few different 92mm fans that didn't achieve the cooling I was looking for on my Ryzen 7 4.1 OC.I was about to give up when I decided to give this a try because of the price & specs I thought "what the heck why not give it one last try..."It exceeded all my expectations & ended up moving double the air of the corsair 120mm fan it came with on just 75% speed.It is noisy but very well built. If you set it to 50% it is actually much quieter Which is what I have it set to at idle & 75% for my gaming sessions. If you set it to 100% it does sort of sound like a hairdryer but it moves tons of air!

Not sure if it's this or the combination of the new Arctic MX-4 thermal compund i installed at the same time but the CPU temp is much cooler than before. Generally stays around 35°C! & fan runs @ ~1900 RPM. At this speed the fan is still pretty quiet. At full speed however, it is kind of loud. Great price & i would surely recommend this!Update: 6/23/18Fan failed today. While i do keep my PC on almost 24/7, I've never had a BRAND NEW [CPU] fan fail within 1 year. In fact, until i had bought this replacement fan, I'd never had to buy one. Taking off one star, but will buy another to see how long that one lasts. Worked well while it worked =)

These work as advertised. According to my fan profile software these have a minimum of 400rpm and max out between 2000-21000 rpm. When maxed out they are loud but you won't really need them to go full speed at any time, unless your system is seriously overheating.When I set my profiles to silent mode you can barely hear them.In standard mode I have all fans at 800 RPMs and it effectively keeps everything cool while under regular office use and you can kind of hear they fans but its not noticeable at all.In turbo mode I have all fans at 1200 RPMs and you can hear them but not so much that it drowns out there game audio. And at this speed my motherboard stays at room temperature and my CPU stays between 100-110F.These work perfectly in PWM mode so your motherboard can control the speeds of the fans with custom profiles. Again, there will never be a time when you need these to be at full speed unless you are seriously overheating your system. But it's good to know that you've got it if you need it.The blue LEDs are not super bright but that's fine with me.

So...first and foremost, these seem to be of at least average quality as far as case fans go - and I've built hundreds of PCs. One pointed word of advice though...if you don't have system fan headers on the motherboard to control these (like, vary their speed by temp), then you're going to want to find something else.The machine I needed these for had a budget motherboard that only had 2 fan headers - one for the CPU fan, and one at the rear for the exhaust fan...I bought 2 of these fans for the front of the case, and had to hook them up straight to the power supply via the included molex adapters.Bad idea - when these things are running at 100%, which is what you'll get when you just plug a fan directly into the PSU, they are LOUD. Like...server fan loud. On the flipside...they move a LOT of air that way...but holy crap dude.I wound up just unplugging one of them...because the noise would have been unbearable otherwise, and frankly one fan by itself at that point was moving more than enough air on it's own. The kid who's PC I was working on isn't going to care about the noise from the one remaining fan...especially considering he always has his headphones on. But I don't think any adult would tolerate that amount of noise, even from one fan.So either make sure there's available fan headers on the mobo for these, and be sure to set the BIOS to vary their speed by temp...or have some other fan speed controller available. Otherwise...these are not the fans you're looking for.
