Cooler Master MasterFan Pro 140 Air Flow- 140mm High Air Flow Black Case Fan, Computer Cases CPU Coolers and Radiators

I picked up an NZXT h500 case to replace my old Antec Nine Hundred because the Nine Hundred had no where to install a modern AIO radiator. It also had to fit in a kinda small space. Well I was happy about everything except there is not much airflow for the GPU in that case. Replacing the top 120mm exhaust fan with this 140mm high flow fan surprisingly solved my problem as it now has to suck air in from the back near the PCIe slots.It's not super quiet at full and the speed selector is actually on the fan shroud instead of a lead so in an exhaust install you cant get to it but it moves a lot of air for its size!

Whisper-quiet, mounted easily within my new Cooler Master case - I top-mounted it, for outflow - and works well.

This is a great fan. Can be a little noisy at full speed but i can zone it out if it's at a constant speed

its a pain to screw into a side panel on a Cooler Master N400 and its loud Evan when set to ''s'' silent.after about a week it doesn't make the sound anymore I don't know if it had to be broke in or what but it works fine now

Great pwm. 4 pin fan without the rgb. My case needed some 140 mm fan with pwm control but I have no windows so rgb is a waste.

out of 5 140 masterfan pro air flows, three rattle. all three rattle mounted horizontally and one also rattles vertically. just requested a refund for those three. kinda hard to use them on my radiators when they rattle so awfully. also ordered one 120 air flow to use as exhaust in my case. it too rattles both horizontally and vertically. issued a return for another 120 air flow. cooler master has always been my go to for fans and this is the first time i've had complaints with their fans. i love their blade master, sickleflow, and silencio series. also loved their excalibur series back in the day. never used their jetflos so these are my first time with their pom bearings... the two 140's that work perfectly fine i kept for intake on my case. they work exceptionally well. very quiet even at performance and moves a ton of air.edit:my 120mm air flow replacment rattles as well. when I press just lightly against the fan hub while its spinning, it stops. which tells me the blade assembly is not properly aligned and sealed onto the motor. the QC of these fans are atrocious and seriously saddens me cooler master would release such poor QC fans. i updated my rating from three stars to two stars because of this. now i'm considering requesting a refund. i feel horrible for amazon but what can I do? i paid for non-defective fans and recieved defective ones. out of seven fans total now, only two came functional.edit again:so the two front fans i said worked fine? they now are starting to rattle. one rattles constantly and the other every now and then. i'm sending them back and updated my rating to one star. i really tried hard to see if it was user error, but its not... if i press gently on the fan blade hub the rattling stops. the fans simply get off balanced.

Would not recommend.Yes they move good air when you want them to.No they are not quiet. They motor is quiet but every MasterFan I have received has made a bearing noise at low speeds and a couple make the noise all the time.

switched out my older NZXT exhaust fan with this one and put it on the medium power mode and made my cpu temp. drop 5c. pushes lots of air out of case with out being to noisy.
