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 eggsGreat fan for the price

Pros: Got the fan for 8 bucks after taxes. They are great for a push and pull config on radiators.

Cons: No cons I'm happy with what I got for 8 bucks

Other Thoughts: Would be nice if the fan came in different colors.

1 out of 5 eggsGarbage fan

Pros: Cheap price. Quiet when it's new.

Cons: Cheap quality. This fan came stock with a Cooler Master Hyper 212 EVO CPU cooler and it started making a grinding noise in less than 6 months. I got another one from Cooler Master under warranty and in less than 4 months it was doing the same. Replaced with a Noctua NF-F12 PWM Cooling Fan and haven't had a problem since.

Other Thoughts: I would think that something as important as a CPU cooler fan would be of much better quality and I expect better from Cooler Master.

Manufacturer Response:

Hello Brian H,

We apologize for the trouble you are experiencing with the Blade Master 120mm fan. Please contact us so that we can get you a replacement and rectify the issue.

4 out of 5 eggsGood black PWM fans

Pros: -Non neon.
-PWM.
-Very quite when installed horizontally even at 2000rpm.
-Fairly good air flow.

Cons: -The mounting screws are silver and don't look very good showing on the side exterior of my all black/red build.
-When these fans are mounted vertically (intakes on side panel) they are much more noisy then mounted horizontally. In this setup they become audible over 1000rmp (50%)

Other Thoughts: I have only just installed these fans so I can't speak to their longevity but overall I'm happy with them. Since my MB controls all my fan speeds I just set the side intakes to run at lower speeds to keep them quite unless my temps are peaking. Now I just got to find a place to buy black mounting screws.

1 out of 5 eggs

Pros: Good when they work?

Cons: Two out of five Began vibrating and making horrible noises after 4-months, three out of five began vibrating and making horrible noises after 6-months. You only get the 30-Day In-Store warranty for Cooler Master products with out Serial Numbers. Thanks so much for a cheap piece of garbage. Yah!

Other Thoughts: Find a brand that actually give you 1-year warranty at the very least.

Manufacturer Response:

5 out of 5 eggsGreat

Pros: Fits as a second fan for the Hyper 212 Evo.
Works well in the setup I have.

Cons: Not really a con to me, but it's a LITTLE louder than the stock Hyper 212 EVO fan.

Other Thoughts: Works like a charm
