3. Installation Guide
Before starting, ensure your system is powered off and unplugged. Refer to your motherboard manual for CPU and RAM installation if not already done.
3.1 Prepare the Motherboard
- Remove any existing CPU cooler and clean off old thermal paste from the CPU IHS (Integrated Heat Spreader) using isopropyl alcohol.
- Identify your CPU socket type (Intel LGA or AMD AM).
3.2 Install Mounting Hardware
For Intel Sockets (LGA1700/115x/1200/2011/2066):
- Place the Intel backplate behind the motherboard, aligning the holes with the CPU socket mounting holes.
- Insert the appropriate standoffs through the motherboard from the front, screwing them into the backplate.
- Attach the Intel mounting brackets to the standoffs using the provided screws.
For AMD Sockets (AM4/AM5):
- Remove the plastic retention clips from the stock AMD backplate (keep the backplate).
- Install the AMD standoffs onto the stock backplate.
- Attach the AMD mounting brackets to the standoffs using the provided screws.

3.3 Apply Thermal Paste
Apply a small, pea-sized amount of thermal paste to the center of the CPU IHS. Do not spread it; the pressure from the cooler will distribute it evenly.
3.4 Mount the Heatsink
- Carefully place the heatsink onto the CPU, aligning the mounting holes on the cooler base with the mounting brackets.
- Secure the heatsink by tightening the spring-loaded screws in a diagonal pattern until snug. Do not overtighten.
3.5 Install Fans and Connect Cables
- Attach the two TL-K12 fans to the heatsink using the provided fan clips. Ensure the airflow direction is correct (typically blowing towards the rear of the case).
- Connect the 4-pin PWM fan cables to the CPU_FAN and CPU_OPT (or CHA_FAN) headers on your motherboard. The Y-splitter cable can be used if only one CPU fan header is available.

4. Operating Instructions
Once installed, the Thermalright Phantom Spirit 120 EVO operates automatically, controlled by your motherboard's PWM fan headers.
4.1 Fan Speed Control (PWM)
The TL-K12 fans utilize Pulse Width Modulation (PWM) technology, allowing your motherboard to dynamically adjust fan speeds based on CPU temperature. This ensures optimal cooling performance while minimizing noise during lighter loads.
- You can configure fan curves in your motherboard's BIOS/UEFI settings or through compatible software provided by your motherboard manufacturer.
- The fans operate at a maximum speed of 2150 RPM ±10% and produce a maximum noise level of ≤27dB(A).

4.2 Initial System Check
After installation, power on your system and enter the BIOS/UEFI to verify that the CPU temperature is within normal operating limits and that the fans are spinning correctly.
5. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your CPU cooler.
5.1 Cleaning the Heatsink and Fans
Dust accumulation can impede cooling performance. It is recommended to clean the cooler every 6-12 months, or more frequently in dusty environments.
- Power off your computer and unplug it from the wall outlet.
- Carefully remove the fans from the heatsink by detaching the fan clips.
- Use compressed air to blow dust out of the heatsink fins. Hold the can upright and use short bursts.
- Clean the fan blades with a soft cloth or compressed air. Hold the fan blades to prevent them from spinning rapidly during cleaning, which can damage the bearings.
- Reattach the fans to the heatsink.
5.2 Thermal Paste Reapplication
While not frequently required, reapplying thermal paste every few years can help maintain optimal thermal conductivity. If you notice significantly higher CPU temperatures, consider reapplying thermal paste.
6. Troubleshooting
If you encounter issues with your CPU cooler, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| High CPU Temperatures |
