Easily connects to many of ABIT's new motherboards through USB, this little device can perform tasks such as overclocking, Fan speed measuring, CPU frequency readings, Tempatures (CPU, SYS, PWM, and VGA, Voltage readings, new email notifications, room tempature, and ofcouse, the time without this use of windows.
