When ultra-high performance coolers demand additional performance, count on Blade Master PWM fan series to increase cooling efficiency. Blade Master offers a balance of high air pressure with balanced airflow and minimal noise levels. With the Blade Master family of 120mm, 92mm, and 80mm fans, unique wave-form blades create increased pressure that exceeds competitor fans at the same airflow. The highest air pressure allows Blade Master fans to blow directly through dense performance heat sinks for extreme cooling.

  • newegg High Performance Featuring distinguished wave-shaped blades, the COOLER MASTER R4-BMBS-20PK-R0 provides up to 3.90 mmH2O of air pressure that triumphs over competitors at the same air flow for better cooling performance.
  • newegg Silent Operation The PWM fan with adjustable fan speed ranging from 600 - 2000 R.P.M guarantees the best ratio between performance and noise level. The anti-vibration rubber pads around the edges dampen noise for more quiet operation.

5 out of 5 eggsSimple Install, does the job

Pros: -Quiet
-Works as advertised

Cons: -None yet

Other Thoughts: Installed in a push-pull config for my CPU cooler and it was a simple task. I did purchase a fan splitter so that both fans are being run at the same speed (since they're being controlled by the same header).

5 out of 5 eggs

Pros: Moves a decent amount of air for the sizes. Not too bad of a price. I bought it for $10.

Cons: Louder then the three other types of fans. When I unplug this fan my computer is dead silent but with this fan in it has a pretty good hum to it.

4 out of 5 eggsIt works

Pros: Relatively inexpensive and it works.

Cons: Annoying faint high-pitched humming sound.

Other Thoughts: Originally installed Hyper212 EVO and the original fan it came with was very silent; like you didn't know the computer was on. Bought this replacement fan as original fan not sold separately. Since installing it, a faint high-pitched humming sound has been driving me insane. I like CM products but maybe this one was just a lemon.

3 out of 5 eggsWorks fine, absurdly short life

Pros: It move a lot of air in an efficient manner.
It's PWM.
Comes with vibration dampeners.

Cons: The "long life doesn't last very long.

Other Thoughts: It wouldn't be too bad of a product overall, but the ideally functional product life is unreasonably short.
The noise seems to be caused by the interaction of the electromagnet driving the fan and the ceramic magnet ring attached to the fan blade. Perhaps the electromagnet is becoming magnetized in it's typical use.
I wonder if I could take the fan-blade unit and attach it to another, more stable, driving unit.

4 out of 5 eggsWorks, but not the best CFM/noise ratio

Pros: Can be pretty cheap on sale.

Cons: Ugly colored fan cable
Louder than other similarly-priced fans
Doesn't move as much air

Other Thoughts: Bought these when I didn't know much about fans. They work though.

1 out of 5 eggsDo not buy

Pros: Worked for about two months.

Cons: I have owned two of these fans and both have started breaking after two months. One day you will turn on your computer and hear a very loud and very annoying clicking.
