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.

2 out of 5 eggsExpensive for a sleeve-bearing fan that shouldn't be mounted horizontally

Pros: Reasonably quiet (When mounted vertically)
Moves a decent amount of air
Keeps parts cool

Cons: Expensive for a Sleeve Bearing Fan
Shouldn't be mounted Horizontally
Sputters and makes noise, then eventually dies within months if mounted horizontally

Other Thoughts: I had one of these come with my Hyper 212 Evo cooler. I had to mount it horizontally to get the best airflow in my case, and the thing started making grinding noises within days of that happening, and still did during startup for months until I replaced it with a cheaper Arctic F12 120mm fan with fluid-dynamic bearings.

I do not recommend buying this fan when you can buy a ball bearing or fluid dynamic bearing fan that can be mounted horizontally OR vertically and has a longer lifespan in general for the same price or less.

5 out of 5 eggsCooling fan.

Pros: It does what it's supposed to reliably. Bought to replace Scyte Ultra Kaze performance fan which had a loose fan attachment and bad bearings. Basically a P O S.

Cons: Not that quiet.

5 out of 5 eggsOldie but goodie

Pros: I Purchased the hyper 212 plus when it first came out, and it`s still running great. I got the second fan for it a month later and it`s also quiet with no problems I got another hyper 212 + for my other system last year and runs great also, just purchased second fan for it yesterday, very happy with it

Cons: Very Happy

Other Thoughts: Highly recommend. Cheap but keeps system as cool or cooler than most expensive ones

3 out of 5 eggsSo So on Reliability

Pros: Were relatively quite with adequate air flow.

Cons: One of the two developed the typical vibration and noise of bearing failure.

Other Thoughts: The unit that failed is mounted horizontally rather than vertically. I suspect that the design does not have adequate thrust bearing capability leading to the failure.

5 out of 5 eggs

Pros: Solid fan with good airflow, pressure and low noise. It also has PWM control which I like

Cons: A little expensive but you can't really get the same quality/features for less

2 out of 5 eggsLet the buyer beware

Pros: Quiet

Cons: Little more than a month after installation, the fan developed a vibration on boot-up. I expect it will soon fail altogether.

4 out of 5 eggsThe fan that growls

Pros: Seems very sturdily built. The blades are made of unusually thick and rigid plastic. Moves a good amount of air. Silent at lower speeds.

Cons: Makes a rumbling, almost growling noise when it kicks into higher speed. I received this fan with my Hyper 212 cooler over a year ago and finally decided to replace it due to the noise it makes when my system is under load.

also, the wire is laughably short.

Other Thoughts: After recently replacing it with an Arctic Cooling F12 I'm not sure why I didn't replace it many months ago.

3 out of 5 eggs

Pros: Decent build quality. Pushes a good amount of air. I have had them in push/pull on my hyper 212 as well as my h80i and they haven't let me down yet.

Cons: Little noisy.

1 out of 5 eggsDoesn't hold up over time

Pros: Had it on my CM Hyper T4 in a push/pull. Kept my CPU cool while it lasted. Four pin.

Cons: Purchased one in March of 2014. Within a week the fan started making a terrible noise. Newegg sent me a new one, and the second fan started making the same noise a few weeks ago - about five months use.

Other Thoughts: Wish it had a warranty longer than 30 days.
