4. Installation
4.1 Safety Precautions
- Ensure your computer is powered off and unplugged from the wall outlet before installation.
- Discharge any static electricity by touching a grounded metal object to prevent damage to components.
- Handle all computer components carefully to avoid physical damage.
4.2 Hardware Installation
- Open your computer case.
- Locate an available 5.25-inch drive bay at the front of your computer case.
- Slide the Aerocool X-Vision unit into the chosen drive bay from the front of the case until it is flush with the bezel.
- Secure the unit with the provided mounting screws on both sides of the drive bay.
- Connect the 4-pin Molex power connector from your power supply to the corresponding port on the X-Vision unit.
- Connect your case fans to the fan headers on the X-Vision unit. Each header is typically labeled for a specific channel (FAN1-FAN5).
- Attach the temperature sensors to the components you wish to monitor (e.g., CPU heatsink, GPU, hard drive, case interior). Ensure good physical contact for accurate temperature readings.
- Carefully route all cables to maintain good airflow within the case.
- Close your computer case.
5. Operating Instructions
5.1 Initial Power On
After completing the installation, power on your computer. The X-Vision LCD display will illuminate, showing current fan speeds (RPM) and temperatures (°C/°F) for each connected channel.
5.2 Button Functions
- C/F Button: Toggles the temperature display unit between Celsius (°C) and Fahrenheit (°F).
- Light Bulb Icon Button: Turns the LCD backlight on or off.
- SET RPM Button: Used to select a fan channel and then adjust its speed. Press repeatedly to cycle through channels.
- SET TEMP Button: Used to select a temperature channel and then set its alarm threshold. Press repeatedly to cycle through channels.
- VIEW Button: Cycles through the display of different channels or modes, if applicable.
- Rotary Knob: Adjusts values (fan RPM, temperature alarm threshold) when in setting mode. Turn clockwise to increase, counter-clockwise to decrease.
5.3 Setting Fan Speeds
- Press the SET RPM button. The display will highlight the fan channel currently being adjusted.
- Press SET RPM repeatedly to cycle through the five fan channels (FAN1 to FAN5).
- Once the desired channel is selected, rotate the Rotary Knob to increase or decrease the fan speed (RPM).
- The new setting will be saved automatically after a few seconds of inactivity or by pressing another function button.
5.4 Setting Temperature Alarms
- Press the SET TEMP button. The display will highlight the temperature alarm setting for the currently selected channel.
- Press SET TEMP repeatedly to cycle through the five temperature channels (TEMP1 to TEMP5).
- Once the desired channel is selected, rotate the Rotary Knob to set the desired temperature threshold.
- If the monitored temperature exceeds this threshold, an audible alarm will sound, and the corresponding temperature display will flash.
- The new setting will be saved automatically after a few seconds of inactivity or by pressing another function button.
6. Maintenance
- Keep the front panel clean using a soft, dry, lint-free cloth. Avoid using abrasive cleaners or solvents, which may damage the display or finish.
- Periodically check all fan and temperature sensor connections to ensure they are secure and have not come loose.
- Ensure temperature sensors maintain good contact with the monitored components for accurate readings.
- Dust accumulation inside the computer case can significantly affect cooling performance. Clean your computer's interior regularly to maintain optimal temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is off or not illuminating. | No power connection or loose power cable. | Ensure the 4-pin Molex power connector is securely attached to both the X-Vision unit and the power supply. Check that the computer is powered on. |
| Fan not spinning or RPM not displayed for a channel. | Fan not connected, faulty fan, or incorrect fan type. | Check the fan connection to the X-Vision unit for the specific channel. Test the fan by connecting it directly to the motherboard or another known working power source. Ensure the fan is compatible. |
| Temperature reading is inaccurate or missing for a channel. | Temperature sensor not properly attached, faulty sensor, or loose cable. | Ensure the temperature sensor is making good, direct contact with the component being monitored. Check the sensor cable connection to the X-Vision unit. Replace the sensor if suspected faulty. |
| Overheat alarm sounds frequently. | Alarm threshold set too low or actual component overheating. | Adjust the temperature alarm threshold using the SET TEMP button to a more appropriate level. Verify system cooling and component temperatures using other monitoring software to confirm if actual overheating is occurring. |
