3.2 Magnetic Connection (Daisy-Chaining)
The CT120 EX fans feature MagForce 2.0 for magnetic daisy-chaining, reducing the need for multiple cables between fans. Align the magnetic contact pads on the side of the fans and gently push them together until they click into place. MagForce 2.0 features larger Pogo pin contact pads for improved tolerance and connection stability.

3.3 Power and ARGB Connection
Connect the provided cable to the last fan in your daisy-chain. This cable will split into two connectors:
- 4-Pin PWM Connector: Connect this to an available 4-pin fan header on your motherboard. This allows for fan speed control.
- 5V ARGB Header (3-Pin): Connect this to an available 5V addressable RGB header on your motherboard. This enables software control of the fan's lighting effects.
Caution: Do NOT connect the 5V ARGB header to a 12V RGB header, as this will damage the LEDs.
3.4 Mounting the Fans
Secure the fans to your PC case or radiator using the appropriate screws. The fans are equipped with four round undetachable anti-vibration rubber pads on each corner to dampen vibrations and reduce noise.

4. Operating Instructions
Once installed, the Thermaltake CT120 EX ARGB Sync fans offer customizable cooling and lighting.
4.1 Fan Speed Control (PWM)
The 4-pin PWM connector allows your motherboard to dynamically control the fan speed based on system temperature. You can configure fan curves and profiles through your motherboard's BIOS/UEFI settings or dedicated software utilities provided by your motherboard manufacturer.
4.2 ARGB Lighting Control
The 9 addressable LEDs in each fan provide 16.8 million uniform colors. To customize the lighting effects, use your motherboard's ARGB sync software. Compatible motherboard software includes:
- ASUS Aura Sync
- MSI Mystic Light Sync
- GIGABYTE RGB Fusion 2.0
- BIOSTAR RGB Sync
- ASROCK Polychrome Sync
Install the relevant software for your motherboard and use it to select colors, patterns, and synchronize lighting across all compatible components.

5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your cooling fans.
- Dust Cleaning: Periodically clean dust from the fan blades and frames using compressed air or a soft brush. Ensure the PC is powered off and unplugged before cleaning.
- Connection Check: Occasionally verify that all magnetic and cable connections are secure.
- Avoid Liquids: Do not use liquid cleaners directly on the fans or electrical components.
6. Troubleshooting
If you encounter issues with your Thermaltake CT120 EX ARGB Sync fans, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fans not spinning | Loose or incorrect PWM connection. Insufficient power. | Ensure the 4-pin PWM connector is securely attached to the motherboard fan header. Check BIOS settings for fan control. |
| ARGB lighting not working | Loose or incorrect ARGB connection. Incorrect motherboard header (e.g., 12V instead of 5V). Software issue. | Verify the 3-pin 5V ARGB header is correctly connected to a 5V ARGB header on the motherboard. Ensure motherboard ARGB software is installed and configured. Restart the software or PC. |
| Excessive noise | High fan speed. Obstruction. Loose mounting. | Adjust fan speed via motherboard software or BIOS. Check for cables or debris obstructing fan blades. Ensure fans are securely mounted with anti-vibration pads. |
| Magnetic connection is loose | Improper alignment. | Ensure the magnetic contact pads are fully aligned and pushed together firmly until they click. |
