Feature:1. [Time Display] Made of high temperature resistant industrial plastic materials, the CPU temperature controller supports perpetual calendar time display.2. [Optical Drive Installation] The CPU temperature controller optical drive is installed and supports more than 90% of the common cases on the market.3. [Alarm Temperature Settable] This alarm temperature can be set manually, ranging from 40 degrees to 90 degrees. When the computer temperature exceeds this range or the fan is stuck, an alarm will sound automatically.4. [Fan Speed Settable] Fan speed can be reduced or increased by manual setting, thereby adjusting the computer temperature and improving work efficiency.5. [Intelligent Detection] Intelligent detection of computer temperature, when the computer CPU temperature is too high, increase the fan speed, when the computer is idle, reduce the fan speed, reduce fan noise.How to Use:I. Switching display of three groups of temperature valuesIn the initial state, press MODE SW to switch the display of the three groups of temperature values. The sequence of switching is: CPU→HDD→SYS→CPU→……II. Turning on and off the alarm clock functionIn the initial state, press ALARM C\F SW to startTurn off the alarm clock function.III. Full screen displayIn the initial state, press and hold SPEED SW for 3 seconds to display,&nbs
