Deceptive
Cons: When I bought these, they were listed as 90CFM, 19dBa. It's been corrected now, but Cooler Master provided false specs to Newegg and listed the same lies on their website. These actually run more like 24dBa at 90CFM, much louder than advertised. Not even sure how the numbers work out, but they were complete baloney when I bought.
Pros: They move air. |

Loud
Cons: Very loud! Sounds like a small vacuum!
Pros: Moves lots of air Comment:
19 dBA??!! Wrong! |

Does the job, but not great
Cons: Substantially louder than I expected 19dBa to be. Lesson learned!
Pros: Move a lot of air, in my desert home with 80F ambient temps 9 months of the year, I really do need this type of air movement.(I bought 2 of these for my Cooler Master Scout) Comment:
Both of these are on the side of my CM Scout case, and the top one makes a horrendous 'whoosh'ing noise, like its sucking air more than just moving it through. I put my hand a few inches in front of it, and the whooshing noise goes away. I have to learn some things about physics/acoustics to understand this I guess. |

Silent? Vibration and noise
Cons: I purchased 6 fans at the same time. 4 of the 6 fans are noisy as all get out.
Pros: Fans move a lot of air at low rpm. Fit and finish look superb. Comment:
I purchased the Coolermaster's to go with my new Coolermaster 690 Case. While they push enough air that the exhaust stays cool at max loads the sound and vibration are driving me mad. I am trying some anti vibration connectors once they come next week but there is so much noise and vibration I am not sure it will help. |

Noisy
Cons: Bought two of these, and both made an obnoxious grinding noise right out of the box.
Pros: Moves a lot of air. Comment:
Maybe I'm just unlucky, but I'll be sure to think twice about buying Coolermaster fans in the future. |

Great Case!
Cons: The back panel is a little flimsy, but once everything is in place it seems stable enough.
Pros: Great case! I got this one for 30$ with free shipping so it was an excellent deal for that. Plenty of room for everything I needed. Comment:
The tool less design is great!! |

Great Fan
Cons: The fins look kinda cheap but it has had no problem running at it max rpm of 2000. It's sucking so much dust into my case. I hate how dusty this apartment gets:(
Pros: This fan moves a decent amount of air. I added it as an intake fan for my case since it lacked one and needed. Comment:
Great fan. Good price:) |

They work.
Cons: Wish they were on sale.
Pros: Does the job, and are relatively quiet. Comment:
Needed a solid 120mm case fan, and these delivered. Bought 6 to go into two cases, and they get the job done. Wish there was a sale, but that would just shave a few bucks off. No big deal.They're not totally silent, sure, but they are whisper quiet. |

Good Fan
Cons: A bit loud
Pros: CheapGood Air Flow Comment:
I picked this up to use as an intake and it has done a good job at increasing my airflow. At 100%, it is a bit loud for other people, but it does not usually bother me. Good price and does its job. |

Great fans
Cons: None
Pros: Quiet, look nice, and move alot of air. Comes with a adapter but they have a fairly long 3pin cord themselves already. Comment:
I have these all connected to a Asus Maximus II. With QFan disabled they run at their max speed, for the 90 CFM (check CMs website for full detailed specs) and they really do move that much air but are louder, probably 24dba which isnt bad considering the amount of air they move. With QFan enabled, they run @ 1200 RPMs and are near silent, I hear my hard drive over them. Unfortunately with them plugged into the motherboard, I couldn't get them to go at their rated speeds or CFM, to get this I had to plug them into the adapter. I think the specs are dead on about the amount of air and noise they produce for 69CFM @ 19dba. These are the best fans I have come across yet, minus not being able to use my motherboard headers, but thats easily solved with the adapter. I have 2 of these, plus 2 of the blue version (LED) cooling my system now, and temps have dropped considerably 5-10C depending on which part of the system. |

meh
Cons: -Purchased 3 and have ceased using one of them because it began to make an annoying clicking sound-The other 2 have a fair amount of vibration when cranked up to full speed, had them both mounted to the top of my HAF 922 at one point and at high speed they had a harmonic thing going which created a noticeable pulsing hum.-They also throw out a good amount of oil from what I assume is the bearing, the oil ends up coating the blades and the inner ring of the shell, collects a lot of dust because of this-Wouldn't recommended as an intake fan, makes more noise when trying to pull air through the honeycomb on my case's side panel
Pros: InexpensiveMoves a lot of airQuiet by themselvesGreat as a rear-exhaust fan Comment:
Decide for yourself if the performance trade-offs are worth the low cost. I wish CM did a better job of balancing the rotor and sealing up the bearings. Will be buying Scythe S-Flexes or Noctuas next time. |

Good Air Flow
Cons: Loud. This thing says its quit operating, but it is pretty loud.
Pros: Moves a lot of air, nice design, long cord. Comment:
I would say buy if you want a good amount of air flow for a good price, especially free shipping. If you want something thats not loud, dont buy this. |

Perfecto!
Cons: Nope.
Pros: Went in my box without a hitch. Also used for my water cooler's radiator. Quieter than most stock fans at max speed. Keeps board and drive temps around 30 Celsius even under a heavy load. Smooth finish for less dust collection. Comment:
Would recommend for any enthusiast. |

Works great
Cons: * None that I can think of, only time will tell. I do suspect that the specs are a little over exaggerated though.
Pros: * Fairly quiet, I can't hear it in my CM Storm Sniper* Keeps stuff cool* Sleek Comment:
* Good fan for the price, recommended. |

Pretty Good For Sleeve Bearings
Cons: Make more noise then the specs say they should at 100%. Mounted with rubber grommets too.
Pros: Replaced two old Cooler Master 120mm's that came with my 690 case. Placed them on top with exhaust duties and they move way more air. Blue lights are about perfect if you don't like them too bright. Comment:
Might move more air than specs say though might be close call. Either way they do crank out air so I don't mind the noise. |

1 good 1 bad?
Cons: Out of the 2 I purchased 1 seems to be having trouble. If i should decrease the fan speed to anything lower than 100% I end up with a sort of pulsing winding sound. So if i set the fan to 99% it sounds like its dying...
Pros: I purchased 2 of these to replace 2 stock case fans in my Coolermaster Centurion 534. They are louder at 100% compared to the stock fans, except these fans actually move air. My CPU (E8400) temps dropped 9*C and my GPU (EVGA 9800GT) dropped about 4*C but it still can fry an egg. The design of the fans is awesome semi-transparent and no dorky lights. True Beauty. Comment:
Stop with the blue LED fans... buy these :-) |

Nice
Cons: Better bearing would be nice.
Pros: Quiet and move lots of air. I put 3 of these in my antech 300 case and it's helping keep things cool. The fan blades are shaped somewhat like a submarine propeller thus the quiet performance with lots of air moving. Comment:

Not very quiet
Cons: Was noticeable louder than the 3yr old thermaltake fan(finally gave out) it was meant to replace and it moved less air, according to the specs for the previous fan this one should have been much quieter(10dba quieter) and moved more air(20-30cfm more). After moving fan to another system where noise didn't matter the fan lasted 2 months before the bearing started making a horrible grinding noise.
Pros: Looks good Comment:
Maybe I just got a bad one, I guess I'll see after I go through Cooler Masters RMA process. |

Decent Fan for the Price
Cons: I feel like they could make it push a bit more static pressure, as it is designed with HSF use in mind.
Pros: On my Prolimatech Megahalem, it works pretty well. Keeps my Q9550 @ 4050mhz @ 1.2v at an absolute peak of 53c with one fan. ambient temps are around 21c Has decent static pressure (2.94 mm h2o) for HSF fan use, but could be better. Comment:
I cant comment too well on noise, as my main exhaust fan drowns it out for the most part. seems pretty quiet, but its not a personal concern either way. Fan stat of 90 cfm is @ 2000rpm, so keep that in mind. Monitoring your temps is not OCD by any means, you always have to see if the new thermal items make a difference! |

Listen to the quiet
Cons: none
Pros: Very quiet - I replaced both front and back fans with these and it dropped processor temp 8 degree C. Yes, I do monitor it - I'm that OCD. Comment:

I Guess 19db is Load
Cons: Is quiet load as compared to the other Cooler Master stock 120mm case (Elite 335) fan.
Pros: Seems to push a decent amount of air. Low price. Arrow shows flow direction. Comment:
I've ordered a Zalman Fan Mate controller to tame it. |

Not Newegg's fault on this. I filed a complaint with the BBB and CM never responded. Tried contacting their support, but it's virtually nonexistent. If this is the kind of sham that Cooler Master pulls, then I am never going to buy their products again.
