The Helix 120mm PWM fan features the same great performance (high static pressure and low noise) as the Helix 120, but also includes PWM speed control. The advantage of PWM (Pulse Width Modulation) is well known for its energy efficiency, but the more immediate benefit for everyday use is that you can connect this fan to your motherboard 4-pin CPU_Fan header thus directly linking the fan speed to the CPU temperature. Fan speed is then automatically managed by the motherboard based on your preferred settings (please consult your motherboard user manual for adjustment settings). Swiftech also offers a PWM splitter cable to connect multiple fans, and thus share the PWM signal from a single 4-pin motherboard connector, which allows all the fans to work in concert depending on CPU speed.

Fan-tastic! ;)
I've got a swiftech h-240x cpu cooler in my pc (which uses the 140mm version of this fan) so when i had to replace the noisy fans that came in my case i didn't hesitate to purchase this model. High airflow even at 25% using pwm, virtually silent until they get to full speed, and even then it's more air noise instead of droning fan noise.Pros:- high airflow- quiet at all speeds- pleasant noise when you can hear it- strong build quality- swiftech tech support is very responsive- the cable is sleevedcons- not really a con at this price point, but some rubber over the mountpoints would be nice for vibration dampeningseller (titan rig) was superfast in shipping them to me, and contacted me after delivery to ensure that i had any support i needed.

What can i say it's a cable. It works as advertised and arrived sooner than expected from the seller.
