ARCTICP14 PWM PST - PC Fan, 140mm Case Fan with PWM Sharing Technology (PST), Pressure-optimised, Quiet Motor, Computer, Fan Speed: 200–1700 RPM (0 RPM <5%) - White

Love these fans, really good bang for buck. Cool design, seems to function awesome, and super quiet.

I'm like most people who at first didn't think or know that fans were very important. Up to a certain point, I usually had computers that had maybe 1 fan in them. I'm not a gamer, but I work from home on 4 screens and I also trade equities. When I first went on a journey of finding a half decent gaming computer for all the tasks I needed to do, that's when I realized fans were quite important. Once I came to this realization, like many people, I started with Noctua, which as we all know, is one of the best. While I'm still a fan of Noctua due to how compact and amazing the U12a is for CPU cooling(also love their NT-H2 thermal paste), I'm not quite there with their case fans. For me the top case fans are Scythe Kaze Flex and Arctic P series. Kaze Flex just slightly edging out Arctic in a number of case fan shoot outs, however, Arctic has a few things going for them: 1) They come in white 2) They are amazingly quiet without sacrificing cooling 3) They are daisy chainable, so you can attach multiple together and use 1 header on your motherboard 4) They are amazingly inexpensive for the performance you get and almost never arrive in unusable condition. With all that said, even your $30 fans have trouble competing. They don't have rubber corners, but I have yet to install any (P12's or P14's) that have any kind of vibration noise. I had Noctua, Scythe, Phantex, etc...all the 'best' staples, and I'm honestly happiest with the 5 P14's I have in my beQuiet! 500dx case. My 5900x is overclocked to 4.4ghz at 1.25v being cooled by a Noctua NH-U12a. I have my rear exhaust P14 set to 'Performance' mode in the bios, so it's mostly staying at about 60% unless the cpu hits 50 degrees, then it starts to ramp up, hitting 100% at 80 degrees. My motherboard is an AsRock x570 Taichi Razer Edition(I know, not cheap), which has good VRM's. My 2 top and 2 front P14's I have set in 'Normal' mode in the bios, which has them sitting at 50%, so around 6v most of the time. The machine is effectively silent. Whatever sound it generates is usually moreso from the graphics card or cpu cooler ramping up. Even with the overclock, I'm idling under 40 degrees most of the time and at night when the sun goes down and the ac kicks in, I see 36/37 degrees. All in all, I think I'm an Arctic P series fanboy now.

I have been using these fans for a couple of years now and never experienced a problem. The only issue I run into is that the heat from my pc fills my room lol. I have to order a ac unit to keep my room cooler when I am gaming. The price of these fans are so good compared to the overprice rgb stuff I see on the store. I would definietly buy them again.

Fan is working well and providing good airflow for my Fractal North XL case.

After doing a lot of research on fans, this is one of the ones I wanted to try. It's definitely quiet for most of its RPM range, and has a good sound. However, it does have resonance, and this intrigued me.I ran it through it's entire RPM range manually using a Noctua NA-FC1 PWM fan controller, which is more precise than varying voltage, and allows the entire range to be utilized. Then I plugged that setup into a precise bench power supply set to 12 volts (which is easier than connecting it to a running PC that makes noise itself). After trying the RPM range a bit, and slowly ramping up and down multiple times, I counted 5 passes through resonance. Without resonance, it has a good low noise level, however when passing through or staying at a resonance RPM, it makes a significantly annoying whining sound. If you've ever heard a large industrial motor start up and pass through resonance frequencies, it sounds like that, except annoying in this situation, whereas industrial motors sound really cool.After thinking about it a bit, I am not sure if the resonance comes from the fan's motor, the frame, or perhaps interactions between the blade design and the frame, etc. If they can solve the resonance issue these would be excellent fans. In fact, the resonance issue is the only common complaint about these fans, they satisfy other requirements excellently, according to fan reviewers. If you're interested in the resonance issue, research around the web as there's significant discussion about it.

These as others mention will "howl" at certain RPM's. Moreso, I actually notice the howl is less tied to individual RPM ranges and more when the fan ramps up and down on speed. So I setup a stepped fan curve and that took care of the howl.It was for a charity build, but if I was doing my own I might spend the extra for a fan without the howl issue.However there is one clear use case for this that beats all others, as a PSU replacement fan. I used one of these exactly for that, and since it runs at a consistent RPM, it does not howl, and it's virtually silent. Highly recommend and would personally use as a PSU replacement fan.

Purchased 2 140mm and 1 120mm ARCTIC PWM fans to replace the AF120's in my Corsair 4000D airflow case. The Corsair fans had started to develop a whine at certain RPMs that was very annoying. The ARCTICs have only been in the case for a couple of weeks but seem much quieter than the fans they replaced. Hopefully they won't start to whine.

Good reviews from various sites. Inexpensive too. Since I needed greater static pressure, I selected these over other units.They are keeping my system cool but the noise that they make (a rhythmic vibration). I will mess around and see if I can't make them less prone to the vibration noise which may work out. If so then these are perfect. If not, then these are very good anyway.
