be quiet! has officially launched their two new fan series shown at CES, with the Shadow Wings 2 silent fans and the Pure Wings 2 high-speed series of fans, both in 120 and 140 mm sizes as well as standard and PWM versions.

We start with the Shadow Wings 2, which is their lowest-noise fan option:

"Shadow Wings 2 is a slowly spinning and highly optimized case fan and the most silent fan series in the be quiet! lineup. It relies on an array of features to keep its noise level as low as only 15.9 dB(A) at maximum speed. Airflow-optimized fan blades provide reliable cooling and whisper-quiet operation. A new anti-vibration mounting system and rubberized fan frame ensure easy installation and decoupling from the case frame. High-grade rifle bearing technology guarantees a lifespan of up to 80,000 hours. Shadow Wings 2 comes in 120mm and 140mm sizes, with 3-pin connectors or PWM control. Maximum rotational speed for the 120mm models is 1,100 rpm, and 900 rpm for its 140mm sibling."

Next is the Pure Wings 2 high-speed,  which favors cooling performance with speeds of up to 2000 RPM:

"be quiet!’s Pure Wings 2 offers an extremely versatile fan with a great price-performance ratio. High air pressure makes this fan the perfect choice for water-cooling radiators, heatsinks or as a performance-oriented case fan. The versatility of Pure Wings 2 is evident from its integration in several other be quiet! products such as air and water coolers as well as the Silent Base and Pure Base chassis series. Nine airflow-optimized fan blades reduce noise-generating turbulence and ensure high airflow while high-quality rifle bearings guarantee a long lifetime of up to 80,000 hours. Users demanding even higher cooling performance can now opt for high-speed versions of Pure Wings 2. Available in 120mm and 140mm versions with 3-pin or PWM connectors, these offer higher rotational speeds up to 2,000 rpm (120mm), or 1,600 rpm (140mm). Even at full speed, the maximum noise level is no higher than 37.3 dB(A)."

Both new fan series are available now, with pricing as announced as follows for the various models:

  • Shadow Wings 2
    • 120 mm: $15.90 
    • 120 mm PWM: $16.90
    • 140 mm: $17.90
    • 140 mm PWM: $18.90
  • Pure Wings 2 high-speed
    • 120 mm: $12.50
    • 120 mm PWM: $12.90
    • 140 mm: $13.50
    • 140 mm PWM: $13.90

Introduction and Specifications

The JUSTICE from REEVEN is a tower cooler with six heatpipes, and a 120 mm PWM fan with distinctive yellow-and-black styling. But what really matters is performance, and that’s what we’re going to find out about as we pit it against the Intel Broadwell-E test system.

Have you heard of REEVEN? A search on Amazon reveals only a pair of older models, but Newegg carries the full range of coolers and fan controllers the Taiwanese company offers. Prices are low for this segment, with their CPU coolers starting at $24.99, and this JUSTICE cooler priced at $42 on Newegg. What you get for this price sounds impressive on paper, and I wasted no time in finding out how that translated into real-world results.

REEVEN sent along a second 120 mm COLDWING 12 fan for us to test with the JUSTICE, as the cooler includes installation hardware for a dual-fan setup, and I tested the cooler with my Core i7-6800K in both configurations - with both stock and overclocked CPU loads.

Austrian PC Cooling manufacturer Noctua has released a new fan called the NF-A14. The new fan is PWM controlled and aimed at case or watercooling radiator cooling. The NF-A14 uses a square frame and features higher static pressure than the NF-P13 along with a maximum speed of 1500RPM.

The fan kit comes with the fan itself, mounting screws, a rubber mounting system to reduce vibration, a 30mm extension cable, low-noise adapter, and a 4-pin Y splitter cable that allows two PWM fans to be connected to a single motherboard fan header. The new Noctua NF-A14 comes with a 6 year warranty.

Who needs software control when you can roll your own fan controller?

Even with the fancy drivers now that allow you to set a minimum fan speed you will find that it is almost impossible to completely turn the fan off.  If you desire to do so, it is almost impossible to turn the fan completely off, which is something that is almost impossible with either a software solution or with a PWM controller.  Over at Hack a Day you can find instructions on how to create a breadboard project which translates PWM signal to DC and will allow you much greater control over your fan speed.

"[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia 9600GT graphics card, he found that it did not need to utilize the fan while doing mundane things like checking email, but that it still required extra air flow while playing games.

He figured he get the fan to shut off by tweaking the PWM signal, but he found that he could not get the duty cycle under 20% using software, which still caused the fan to run at all times. The circuit he built takes the PWM signal output by the card, cleaning it up before converting it to a corresponding DC voltage. The fan then runs at the same speed it would if driven directly by the PWM signal, though it can now turn off completely when not required."
