product description
AIREN is known for its products such as computer cases, fans, mice and other essential accessories.
This time, however, it comes with support for user comfort in the form of the SilverFour + control panel.
AIREN SilverFour + is a powerful and easy to apply fan speed control to the 5.25 "bay. The red diode panel is capable of controlling up to four fans to reduce the temperature. This allows the panel to reduce the speed and therefore the noise generated by the fans.

The power supply is controlled from 5 to 11.8 V ± 10%.
Also included are very useful interfaces in the form of two USB 2.0 connectors and another eSATA interface.
