Cooler Master Fans are Noisy

  • Summary: There is normal fan noise caused by moving air and then there is bearing noise caused by poor design or material. The 2000 rpm fans have bearing problems that cause a irritating high pitched whine. This is causing problems for my customers. Go with a lower rpm fan for less problems.

COOLER MASTER R4-L2R-20AC-GP Blue LED Case Fan

  • Excerpt: Looks fantastic with blue, and moves a lot of air even though performing it!Can be super quiet. Can also be very loud! One particular of mine sounds like an airplane receiving prepared to take off when it's on full speed.Also the speed on my other fan has been decreasing. Not as well poor correct now, but it makes me wonder how low it will go... I bought two of these 6 weeks ago and they have been steadily declining given that.

  • Excerpt: Blue LEDs. Have good airflow. A tiny loud. Two of my Blue LEDs are greenish for some cause. Not sure if that is a purpose to RMA or not. I didn't know they came with screws, lol.

  • Excerpt: Moves significantly much more air than the more affordable 2-pack CoolerMaster fans, which this replaced, but with drastically enhanced noise. three-pin connection is excellent for minimizing cable clutter. 19 db is a negative joke, much more like 26 db or so. LEDs only visible if utilized as an exhaust fan. If you use it as an intake fan, as I am, they're practically undetectable, even though they do light up the inside of the case.

COOLER MASTER R4-L2R-20AC-GP Blue LED Case Fan

  • Excerpt: Just enough glow devoid of getting vibrant as hell. Fairly quiet. For some reason these fans are difficult to clean. Dust almost turns into glue on the blades. One thing about the material. My exhaust fan is a breeze to clean compared to these. I also clean my situation out every single two months as needed. Airflow on these is not extremely direct, a lot more of a multi-directional poof. Tested this with a smoke box.

  • Excerpt: Appear "cool" in the case and move lots of air! I do agree with other individuals, to be advertised as quiet.... they surely make a lot of noise. If noise is not a element they are fantastic for the cost, the case temp stays fairly close to 85 F. Manufacturer Response:Dear Valued Customer - We sincerely apologize for any inconvenience. If you think the fans are faulty, please let us know via the Live Chat link below so we can rectify the issue and get you replacements.

COOLER MASTER R4-L2R-20AC-GP Blue LED Case Fan

  • Excerpt: The fans appear nice, worked correct off the bat and do push a great bit of air. Cooler master's QC was not undertaking their job, or just suck anyways. I purchased two of these fans, and whilst one of them had color matching LED's (all four are dark navy blue), the other DID NOTƑ dark blue, the other 3 light). the only reason i chose to purchase lighted fans was to have a single color in the front of my case, not two various colors coming from 1 fan.
