3. Package Contents
The ID-COOLING AS-120-K Trio package includes the following components:
- 3 x 120mm Case Fans (AS-120-K TRIO)
- Mounting Hardware (screws)
- (Note: The 'heatsink' component listed in the product data refers to the cooling capability of the fans, not a separate heatsink unit.)
4. Installation Guide
Follow these steps to properly install your ID-COOLING AS-120-K Trio case fans:
4.1 Prepare Your System
- Power off your computer and unplug it from the wall outlet.
- Open your computer case to access the fan mounting locations.
4.2 Mounting the Fans
- Identify the desired mounting location(s) for your fans (e.g., front, top, rear, bottom of the case, or on a CPU cooler/radiator). Ensure proper airflow direction (intake or exhaust) for optimal cooling.
- Align the fan with the screw holes on your case or radiator. Use the provided mounting screws to secure the fan in place. Do not overtighten.

4.3 Connecting the Fans (Daisy Chain)
The AS-120-K Trio fans feature a daisy-chain design for simplified cable management. This allows you to connect multiple fans to a single fan header on your motherboard.
- Connect the 4-pin PWM cable from the first fan to an available 4-pin fan header on your motherboard (e.g., CPU_FAN, SYS_FAN).
- Connect the daisy-chain connector from the first fan to the input connector of the second fan.
- Repeat step 2 for any additional fans, connecting them in series.
- Ensure all connections are secure.

5. Operating Instructions
The ID-COOLING AS-120-K Trio fans utilize Pulse Width Modulation (PWM) control, allowing your motherboard to dynamically adjust fan speeds based on system temperature. This ensures optimal cooling performance while minimizing noise.
- After installation, power on your computer. The fans should begin spinning.
- To adjust fan speed curves, access your motherboard's BIOS/UEFI settings or use compatible fan control software provided by your motherboard manufacturer.
- Configure fan profiles to balance cooling performance and noise levels according to your preferences.

6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your fans.
- Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use compressed air or a soft brush. Ensure the computer is powered off and unplugged before cleaning.
- Inspection: Check fan cables for any signs of wear or damage. Ensure all connections remain secure.
- Environment: Operate your computer in a clean, well-ventilated environment to minimize dust accumulation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan not spinning | Loose cable connection, insufficient power, faulty fan header. | Check all 4-pin PWM connections. Try connecting to a different fan header. Ensure power supply is adequate. |
| Excessive noise | Dust buildup, fan rubbing against cables, high RPM setting, faulty bearing. | Clean fan blades. Ensure no cables are obstructing the fan. Adjust fan speed settings in BIOS/software. If noise persists, the fan may be faulty. |
| Poor cooling performance | Incorrect airflow direction, insufficient fan speed, dust buildup. | Verify fans are oriented correctly for intake/exhaust. Increase fan speeds. Clean fans and case filters. |
