Features    [ Edit | History ]

When ultra-high performance coolers demand additional performance, count on BladeMaster R4-BMBS-20PK-R0 Cooling Fan to increase cooling efficiency. BladeMaster R4-BMBS-20PK-R0 Cooling Fan offers a balance of high air pressure with balanced airflow and minimal noise levels. With the BladeMaster R4-BMBS-20PK-R0 Cooling Fan of 80mm, unique wave-form blades create increased pressure that exceeds competitor fans at the same airflow. The highest air pressure allows BladeMaster R4-BMBS-20PK-R0 Cooling Fan to blow directly through dense performance heat sinks for extreme cooling.

Experience: 2 Years
Cheap, durable, great airflow
I only replaced these from my machine because they don't have built-in lighting. Otherwise, if you're not looking for a glowing aesthetic, these are simply the most reliable and cost-effective things you could get.

Quiet, does a good job of cooling
Quite a short cable
Got this because it was a reasonably priced PWM fan. It's quiet and seems to push a fair bit of air. The one thing to be very aware of is the short length of the cable on it. It was a challenge to get it to plug in to an available socket on the motherboard when mounted as an intake in the front of my case.

I suspect most people buy these to put on a cooler but I wanted to take advantage of the 4 available PWM connectors on my motherboard. The bios adjusts the fan speed with the temperature and you don't need a separate fan controller.

I would have given 5 stars if the cable was longer than 6 inches. I recommend it to use in conjunction with a CPU cooler but be careful if you want to use it as a case fan.

- decent airflow and less than moderate noise
- price steep unless on sale
Bought this as a 2nd fan for my Hyper 212 Evo. This is the model that comes with the heatsink. With 2 fans I did see an improvement of about 2 C. Although I ended up switching the fans out for high performance Corsair fans, but this is still running on my old system replacing the stock Antec ones. I recommend this if you can snatch it on sale for decent airflow.

4 pin. Black. Silent
I needed a 4 pin 120mm fan to put in my sg01w case (you heard it right!). My case was getting hotter with my new i7 2600k overclocked j4.4 ghz, plus a GTX580 in such a tight places, so i have added this fan in the bottom in between the front and the motherboard on the cpu side, it fits perfectly. It is connected in the cpu fan connector and speed faster when needed.

Bas prix lorsque pricematché à 6.60$
PWM donc parfait pour un HSF.
2000 RPM pour un puissant refroidissement.
Bon manufacturier.
Dépassé les 1700 RPM il est plus bruyant mais c'est quand même tolérable pour un PC gamer.
J'ai acheté ce ventilateur pour améliorer la perfomence du refroidisseur OCZ Vendetta 2 sur mon i7 920 en remplacent son ventilateur d'origine de 1300-1400 RPM par celui-ci. Mon CPU étant overclocké mes températures de cores ont baissées de près de 7-8 °C à cause du plus grand débit de ce nouveau ventilateur. Un très bon achat pour mon application.
