ARCTIC P12 PWM - 120 mm Case Fan with PWM, Pressure-optimised, quiet motor, Computer, Fan Speed: 200-1800 rpm (0 rpm <5%) - White, Transparent

Have used these many times and are great value for money. They're quiet and unobtrusive and can be used as a inward fan or an exhaust fan. This unit allows the motherboard and cpu to control the speed of the fan depending on how hot the sensors say the PC and it's components are getting. If used normally they will run slower and if you start running more intense programs then it will adjust the speed upward to provide more fan pressure and therefore more cooling. They're just as good as some more expensive fans but at a fraction of the price.

As a complete newbie to case upgrades, I bought this to replace an 80mm(!) 3-pin exhaust fan that came with my ancient no-name "airflow" case. A few weeks after installing and it's doing an amazing job, being quiet and varying speeds appropriately to keep my GPU/CPU cool. I'm no hardcore current-AAA-game player, but like my older games to look good at 1920x1080 and do use the PC for video and 3D work, so efficient cooling at moderate loads is a must.The packaging is minimal, but the box is a snug fit so the fan was secure inside it. On opening it, I was surprised by how solid it felt for a budget fan. It's certainly got a reassuring heftiness to it. The design is a slick kind of basic that belies the comparatively low price point.It was an absolute dream to install; not even the slightest stripped screw! It does take quite a bit off force to get the screws in, being the self tapping variety into unthreaded holes, but once they're in, they're in tight. I've had no issue with vibration. The cable wraps around the casing very neatly.I had originally meant this static pressure fan to replace my front intake by the drive cage as I'd guess that's where it'd be more effective, but as my original 3-pin 120mm stock fan was working well enough and my back fan wasn't up to the task, I chose to try it out there first (easier to access should it need tweaking or removing). I kept reading how Arctic fans could be hit and miss when it came to noise and quality, but this one seems great. Perfect for someone who wants a quiet, understated, efficient fan that doesn't cost the earth... and without all those flashy lights/lurid colours so many manufacturers think *everyone* wants!After looking at many dearer rival brands, I'm glad I went with this Arctic one. For the price, it more than lives up to expectations and I would buy this or similar from Arctic again - I'm already eyeballing a PWM F12!

I got three of these to replace some older fans as front intakes, they are supposedly pressure-optimised and so should work well pulling air through a fine mesh dust filter.Pros:1. Exceptionally priced at just over £7 yet seem well built and don't look or feel cheap.2. Work well pulling through the dust filter due to their higher static pressure performance. Would work equally well against a heatsink or radiator.3. Extremely quiet! I actually didn't expect them to be so quiet, even ramped all the way up to their maximum speed they are far quieter than I was expecting. At lower speeds they're hardly audible.4. PWM controlled (4-pin) which works well for controlling their speed.Cons:1. You do get a sort of 'resonance' or some kind of slow pulsating sensation at specific speeds, however as long as you don't set them at those speeds it's a non-issue.2. The maximum speed isn't consistent across all the three fans I bought, one tops out at 1753RPM, the second at 1691RPM and the third at 1739RPM. It's not really an issue but just be aware if you're tuning them with PWM the same PWM % won't result in exactly the same speed for each fan, you might want to tune their profile individually.But for a little over £7 a fan, these are exceptional value compared to anything even twice their price.

Almost swapped to a new desktop thinking that my fans can't be much louder than these.How wrong I was... Not only are these keeping my tower much cooler, but they can barely be heard in comparison to the jet engines that I had before.

Very happy with the fan, and super cheap considering it's performance.

I bought two of these fans to add with my corsair 4000d stock case fans, and realised just how much better they were. I instantly bought 3 more and replaced the stock fans and now my PC is absolutely silent whilst performing better than my previous case fans! PWM allows for a lot of customizability, and 6 year warranty is always a pleasure. Will definitely look into Arctic for cooling solutions in the future!

Does what it claims to do at good price and easy enough to fit.

Good performing fans and good value

I replaced most of my case fans with these, and CPU/GPU go from 86/94 under load to 68/83My PC is a lot quieter and I've found no issues after a few months

Bastante bueno y a muy buen precio.PMW, silencioso (aunque esto en mi caso) y de buen rendimiento.

Nadiren hafif bir ses yapıyor, kaliteli ama daha da kaliteli olanlar var ama 2 kat ödemeye değmez. Benim beklentimi karşıladı, eksiksiz, paketlenmesi güzel geldi.

I have built quite a few pc's and everytime someone wants more fans, I always point them to these. I have never had a problem with them and they are nice and quiet. Gets the job done and makes sure that all my components stay nice and cool under load.

Es la segunda vez que lo pido y funciona perfectamente. No hace ruido que es algo que me preocupaba.Lo recomiendo 100%
