That#39;s Life
Experience: 2 Years


Still working after 2 years. Price when on sale.
Good air flow and noise levels for the price paid. Not the quietest but given the price, it's acceptable.

Experience: 1 Years


moves air around
could have been cheaper
to be fair, it works fine. not too loud. not too underperforming as air volume is concerned.

will buy again.

Experience: 14 Days


Great cooling
none yet
Cooler master make reliable products. I am a fan of 120 mm fans, they move more air for the amount of noise.

Experience: 1 Months


These push a good amount of air at full power... but... see cons >
This product gets 3 stars because of how LOUD they are, exactly like another reviewer stated "they sound like a jet engine" when at full power. I had to plug them into a fan controller just to dial them down to a bearable level.

Overall, they still push air but cannot be the same db level they claim... and having to dial them down with a fan controller means I am not able to gain their full cooling potential.

Experience: 2 Months


Lots of air flow
load if on full do not come with fan controller.
Put 2 of the in a coolermaster case and had to put fan controllers on them because they were too loud. I turned them down halfway much quieter now and still have great air flow.

Experience: 5 Days


Comes with 3 pin-Molex Connector
Moves a decent amount of air
LOUD! Holy cow....There's no way these can be the DB rating they have. I put 2 of them into my CM690 II case to replace 2 failed Yate Loon's that are rated at a higher DB. These things sound like rocket ships taking off, I had to take them out just after a couple hours of use. I'd have thought it was defective but both fans I have produce the same level of sound.
Moves air decently, but SO loud. Maybe my perception of "loud" is warped but I will never get one of these again.

edit: I've since plugged the fan in while holding it in my hand and it is whisper quiet. As soon as I mount it to the side panel it sounds like a jet engine. =(

Fairly quiet
Moves lots of air
Using this fan as an exhaust in the back of my CM690II Advanced case. Its louder than the stock fans but it spins twice as fast at 2000rpm and moves way more air. Was able to price match it down to $5 so is a great deal for a inexpensive, effective fan.

Experience: 7 Days


Moves air like it's supposed to
Would purchase again for sure, it was used in my roommates computer as an intake and it helped drop  his ambient temps quite nicely. I have 2 of the green LED version, one added to my Hyper 212 Evo as a pull fan and it works awesome, the other is used as intake like my roommate. 4stars

Experience: 6 Weeks


I bought these for a NAS system that I wanted to keep cool. So far I have had no problems with these fans. I price-matched them down to $5 and at that price, it's an awesome deal. They've been running quietly and very effectively.

Experience: 1 Days


Lot of air goes through
Screws they came with are silver.
It seems that the fans can only be used as exhaust. I tried putting one as intake and noise level was horrible even at 1000RPM. At 2000rpm I was grinding my teeth.
At 200rpm as exhaust I could hear them but it was not bad at all. When I am not using PC for anything resource heavy I turn them down to 100rpm at can barely hear anything.
The screws should have been black. But that's a small thing.
Otherwise I am pretty happy. I ran a test for 1 hour maxing out CPU and it barely got above 45C with this fans sucking the hot air away. That's the important thing for me.
