Features    [ Edit | History ]

When ultra-high performance coolers demand additional performance, count on BladeMaster R4-BM8S-30PK-R0 Cooling Fan to increase cooling efficiency. BladeMaster R4-BM8S-30PK-R0 Cooling Fan offers a balance of high air pressure with balanced airflow and minimal noise levels. With the BladeMaster R4-BM8S-30PK-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-BM8S-30PK-R0 Cooling Fan to blow directly through dense performance heat sinks for extreme cooling.

High airflow, potentially quiet
High speed on Gigabyte H77N-WIFI
I'm not sure if the problem lies with my motherboard (Gigabyte H77N-WIFI) or the fan, but even with the BIOS set at it's SILENT fan control setting, this fan starts at 1200 RPM and quickly stabilizes at about 1500 RPM, which is way too fast, and noisy for a cool, idle system. HWMonitor also doesn't seem to detect it as a PWM fan.
I replaced it with a GELID Silent 8 3pin fan, which spins much slower, and as a result, much quieter.
This fan would be quiet if it would spin as slow as 800 RPM.

good build quality with pwm
pricematch needed
neededsome quiet fans. at 3000rpm these fans are noisy but pwm control lets them operate aslow as 800 rpm still moves decent air at 1400rpm and quiet.using 4 push pull on hw labs m160 rad.

PWM speed control
None yet discovered
The true test of a fan in a critical application is its long-term reliability, and I've only just gotten it so can't offer anything meaningful in that regard.
I will say that the two specimens I got to replace existing fans are no louder than the non-name originals while claiming to produce about 10 CFM *more* airflow at the top-end; there's little to no whine my ears can hear over ambient, and the wind noise is noticeable but not distracting when the fans run at full tilt. Throttled, they can be quite unobtrusive.

Great price, quiet operation.
I replaced 3 older Antec Tri Cool fans with these ones and I must say the first thing I did notice was how quiet they were in comparison with the Antecs. You could barely tell that they were running. I like the fact that these are PWM fans. With a price match, I was able to get these at an awesome price. Overall, these are a good match for my older Lian Li PC60B case. Highly recommended.

I replace my old fan with this one and the temperature in the case drop  by 3°C. It is very silent.

Decent price, fairly quiet.
Would think these 80mm would be cheaper buy now?
Decent 80mm fan. PWM is nice touch.

I bought this fan as a case fan to help cool the case. So far my experience with this fan has been positive. It's fairly quiet and I had to put my ear next to the fan to make sure that it was spinning. Overall a decent fan and I would purchase it again.
