Zalman launched its pulse-width modulation (PWM) based universal fan controller called the PWM Mate. This nifty little device connects to 4-pin PWM fans (such as those on CPU coolers), and provides more precise fan control than what traditional fan controllers would offer. PWM fan controllers adjust the speed of a fan by supplying the motor pulses of current instead of reduced voltage. The device is able to provide precise fan speed control between 25~100 percent speed. It comes in the form of a hand-held pod that can stay within your chassis or pop out. The main unit measures 55 (L) x 24 (B) x 13.5 (H) mm and uses a 4-pin fan connector to connect to the motherboard and then to the cooler. Those finding it familiar will note that the PWM Mate has been selling as part of the CNPS-10X Extreme's package. Its pricing and availability are yet to be known.
