ARCTIC P12 PWM PST CO - PC Fan, 120mm Case Fan, PWM Sharing Technology (PST), Pressure-optimised, Dual Ball Bearing for Continuous Operation, Computer, 200–1800 RPM (0 RPM <5%)

Used to replace the fan in IW-MS04-01-S265 265w case that I have had for 6 years and drives run 2 degrees Celsius cooler.:-)

Artic Fans are the only fans I will ever use for building or replacing fans. These fans get the job done and are a great value for the money. I've tried other brands which were more expensive and had less airflow. Keeping things cool in your computer is what fans are suppose to do and these do just that. I like how the airflow is more directed rather than spreading out away from the components your trying to cool in the first place. If you want to waste your money go ahead and buy other more expensive fans that do less of a cooling job, it's your computer not mine. I'll stick with these. Save money and keep my computer cooler, it's a no brainer... Check the warranty on these compared to other fans and you'll see it's a win win.

Not much to say here, this fan works great for a low cost. I realized I didn't like RGB fans, so I went with this one and I've been super happy with it. It was easy to install and runs quiet. It blends in well and creates a deep black that looks like the depths of my soul. This isn't a comparison to my levels of happiness, I just play League of Legends. Overall, highly recommend this fan to anyone looking for an understated style of fan.

Replaced a broken fan on a friend's computer with a Fractal case. Fan was the same as the model we replaced, and it works great, just wish it wasn't quite so expensive.

Unless you have a reason to buy more expensive fans (i.e. color, aesthetic, Lian Li Uni fans for single cable connection etc.), buy these! I own these and bequiet silent wings pro, these perform on-par with those. The bequiet build just needed to be all matte black, again, an aesthetic need. If not for that I would have happily bought more of these.

Good and quiet, but one was DOA, returned and got a replacement which was also DOA. Good job guys.

If you need a fan to push through a radiator, this is it. I bought three of these to replace the stock fans on my 360 deepcool castle 360, and when comparing versus those fans and also some corsair ml120 pro "magnetic levitation" fans, it's not even close how much better these fans are to those.For some reason I would have thought that stock fans on a premium 360 aio would be the best suited, but these arctic fans can run at 100% and are quieter than both the stock aio and corsair fans by a mile.Keep in mind that this particular model is for static pressure so you want it for situations where you are pushing through mesh filters or radiator fins. For fans that are general airflow/case fans, get the ones that start with F, I also bought an 80mm fan for exhaust (F8 pwm pst co) and it runs just as great as this one.

These fans are much better than my 13 year old antic fans. Things had gotten noisy and these Arctic PWM fans are quiet and push more air. Definitely worth the price for a 5 pack. The reviews on these are as good as any for a lot less money.
