Description

In tackling your case's cooling needs, there is no 'one fan fits all.' Each of the two 140mm fans in the MasterFan Pro series provides a specific air cooling solution while all being fitted with multiple layers of our exclusive noise reduction technology and adjustable speed profiles. Put together, they work in harmony to cool your entire case and its components. Air Flow fans are ideal for exhausting large volumes of air quickly out of the case. We recommend them for use on the rear or top panels.

One star
It can only be mounted as an exhaust fan. I didn't see that in the description anywhere.

The two 140's that work perfectly fine i kept for intake on my case
Out of 5 140 masterfan pro air flows, three rattle. All three rattle mounted horizontally and one as well rattles vertically. Just requested a refund for those three. Kinda hard to use them on my radiators when they rattle so terrible. As well 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. As well 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 outletpc 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.

Works fine. The different settings are nice to have
I got this along with a couple of the 120mm versions. Works fine. The different settings are nice to have.

Yes, the masterfan pro 140 air flow is like a jet engine having sex with a tornado at its full rpms, but what else do you expect from a fan that moves 106 cfm? There are very few use cases where you'll be running these fans at 100% duty cycle anyway. At most other speeds, these fans are relatively quiet and inoffensive. My problems stem from the surprisingly short cable length and the low-rpm pwm hum. I didn't really expect a nearly $19 fan to have half the cable length of the fan that came with my new case. I as well didn't expect the annoying little rattle. As for the included screws, i used them to install the fans into my enthoo pro m with no troubles at all. I just wish i had a little more cable length to play with without needing to buy an extension for fans i already paid so much for to start with.A further update: one of the fans (the one i said had what i thought to be the pwm hum) emits a massive rattling noise at 600-800 rpm and even worse racket at 1,500 rpm and up. This fan is getting rma'd. The other two fans work well.
