2. Installing the Kraken 280 RGB AIO Cooler

1. Prepare CPU Socket: Apply thermal paste to your CPU if not pre-applied on the cooler's cold plate.
2. Mount Radiator: The Kraken 280 RGB radiator can be mounted in the front or top of the H5 Flow case.
   • Front Mount: Secure the radiator and fans to the front mounting points. The H5 Flow supports up to a 280mm radiator in the front.
   • Top Mount: The H5 Flow supports up to a 240mm radiator on top. For the 280mm Kraken, front mounting is generally recommended for optimal compatibility.
3. Install Pump Block: Carefully place the pump block onto the CPU, aligning it with the mounting holes on the motherboard. Secure it with the appropriate mounting hardware for your CPU socket (Intel/AMD).
4. Connect Cables:
   • Connect the pump's power cable to the CPU_FAN or AIO_PUMP header on your motherboard.
   • Connect the RGB and fan cables to the appropriate headers on your motherboard or a compatible RGB controller/hub.
   • Connect the USB cable from the pump to an available internal USB 2.0 header on your motherboard for NZXT CAM software control.
