About this deal

PWM works by pulsating DC current, and varying the amount of time that each pulse stays ‘on’ to control the amount of current that flows to a device such as an LED. If the duty cycle of a PWM power supply is set to 70%, then the pulse is on for 70% of the time, and it is off 30% of the time. This gives you ample time to get a new one and transfer all your important files from the old drive.

The correlation between duty cycle and brightness is not 100% linear, as the efficiency of LEDs varies with the amount of current supplied.If your Mac is too noisy or overheats too much, the Macs Fan Control software is the best free solution.

Thanks to the supplied 3-way split cable and power supply adaptor, up to 3 fans can be controlled simultaneously.Rather than being powered by a continuous supply of power (which would ordinarily be the case) our DC fan motor is being fed with pulses of power; it is essentially being switched on and off very rapidly. Easily use Razer Synapse software to unlock and customize the pulse width modulation curves for up to 8 fans and enjoy lower noise levels compared to traditional DC powered fansetups. The ARCTIC Case Fan Hub is a 10-fold PWM fan distrubutor that draws power from your PC's PSU via a SATA cable.
