Corsair CO-9050039-WW 120mm ML120, 120mm Premium Magnetic Levitation PWM Fan (2-Pack)

Noisy

Replaced the stock 140mm fans from my h115i and these push/pull more air and lowered the noise produced. This model does not have the extra rubber padding from the pro series but with my setup they are silent without it.

Very nice product, thank you for the fast shipping.

These are pwm fans or 4 pin, and you can plug these direct into your 4 pin headers on your motherboard if you have them. This allows you to control how fast they spin. So if you read or see a review and they only spin these at the fastest settings, they are doing it wrong. Which is why my reviews on youtube are useless.If you are a quite fan freak and aim to run these fans at low settings, you're going to find that these fans are very quiet. Now with that said, no fan with static pressure is going to be 100% silent. And neither are these. But the tiny bit of sound that these do produce is a very smooth high quality even tone, a bit on the midrange of sounds. Just a faint whisper.As far as the construction these fans are over built, insanely sturdy, heavy feel to them in your hand. So i can't recommend these enough.

I am running a corsair hydro series h110i gtx cpu cooling system on a i5-6600k, overclocked to 4,400 ghz. The stock fans got loud when the cpu was stressed, like when playing civilization vi. I swapped the stock fans out for these and wow, continual silence! I?€™m thinking about swapping out my last three fans for these too!

First, the bad. This fan is just a hair thicker than my old fan, and as such, i had to take the wire grill off to get it installed. Hopefully i don't end up with it eating a cable. On max power it was louder than i expected. Not super loud, but i can hear it over the tv if i'm paying attention. I have a fan controller, so i just dialed it back about 30% and it was nice and quiet.On the plus side, it came with nice black screws that go well with my case. It moves a lot of air, which i can feel blowing out the top of the case. Runs very smoothly, and doesn't look bad. Not good, but not bad. Hopefully it'll last longer than the last cheap fans that i bought to go with my lighting scheme last time.

I bought them to go with the color scheme of my build. They do a great job cooling, but aren't the quietest fans in the world. Buy these for performance, not for silence, unless you plan on keeping the speeds down low.

These fans push out a lot of air but they are loud!

Fan design seems to be split about 60/40 between static pressure design and air flow design. I would assume these would make pretty good radiator fans. I used 3 of them to replace the stock 140's in my new air 740 case. They move more air ..... At the expense of a fair amount of increase in noise. They can "roar" quite a bit at 50-100% pwm settings. I have them in standard fan profile mode in place of the stock fans at turbo profile mode. I primarily wanted more airflow and pressure for the front fans which i need to blow as input air to my dual blower style graphics cards which are always loaded at 100% utilization. They can get pretty hot. I knocked about 5 ° c. Off the stable loaded gpu temps with the new fans. That is what i was shooting for. Since the computer is in an unoccupied room, the increase in system noise is not a bother.
