Step-by-Step Installation
- Prepare the Motherboard:
- For Intel sockets, assemble the appropriate backplate by adjusting the clips to match your CPU socket (e.g., LGA 1700, 1200, 115X, 2011, 2066). Attach the backplate to the rear of the motherboard.
- For AMD sockets, remove the existing plastic retention clips from the motherboard, but retain the original AMD backplate.
- Mount the Water Block:
- Ensure the protective film is removed from the copper base of the water block.
- Carefully place the water block onto the CPU, aligning the mounting holes with the backplate or standoffs.
- Secure the water block using the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.

- Install the Radiator and Fans:
- Mount the radiator and fans to an available fan mount location in your PC case (e.g., top, front, or rear). Ensure proper airflow direction (intake or exhaust) based on your case's cooling design.
- Use the long screws provided to secure the fans to the radiator, and then secure the radiator to the case.

- Connect the Cables:
- Connect the pump's 3-pin or 4-pin connector to the CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the fan PWM cables to the CPU_FAN or SYS_FAN headers on your motherboard. Utilize the daisy-chain cable for simplified connection of multiple fans if applicable.
- Connect the 5V ARGB lighting cables from the pump and fans to a compatible 5V ARGB header on your motherboard or an ARGB controller. Ensure correct pin alignment to prevent damage.
Operating Instructions
Once installed, the upHere P240K Liquid CPU Cooler operates automatically. The PWM fans adjust their speed based on CPU temperature, providing efficient cooling while minimizing noise.
ARGB Lighting Control
The 5V ARGB lighting can be controlled via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync, BIOSTAR RGB Sync) or a dedicated ARGB controller (not included). Refer to your motherboard manual for specific instructions on controlling ARGB devices.

Maintenance
Regular maintenance ensures optimal performance and longevity of your liquid CPU cooler.
- Dust Cleaning: Periodically clean the radiator fins and fan blades to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
- Cable Management: Ensure all cables are neatly routed and secured to prevent interference with fan blades or other components.
- Coolant Check: This is a closed-loop system and does not require regular coolant refills. If you notice any leaks or significant performance degradation, contact support.
