noctua NM-AMB15 Offset Mounting Bars
Product Information
The product is the NOCTUA NM-AMB15, an installation kit for mounting a CPU cooler on an AMD motherboard. It includes the necessary mounting parts, such as the NM-AMB15a and NM-AMB15b mounting bars. The kit is designed to provide optimal contact quality and performance for AM5 and Ryzen 5000/3000 series AM4 CPUs.
Product Usage Instructions
Follow the steps below to install the NOCTUA NM-AMB15 on your AMD motherboard:
- Scan the provided code to access multilingual manuals on your phone.
- Ensure you have the required mounting parts: AMD stock backplate (pre-installed on the motherboard), NM-AMB15a mounting bar, and NM-AMB15b mounting bar.
- If there are any compatibility issues or if you are using other AM4 CPUs, choose the standard position (0) for mounting. Otherwise, select the offset position (-7mm).
- Caution: Make sure that the CPU markings on the CPU are pointing towards the CPU. Install the NM-AMB15a bar with the WEST marking on the left side of the socket and the NM-AMB15b bar with the EAST marking on the right side of the socket.
- Fix the offset mounting bars using the screws provided with the cooler. Gently tighten the screws until they stop, but do not use excessive force (maximum torque 0.6 Nm).
- If your CPU cooler is already installed, unscrew it from the original mounting bars and remove them from the backplate.
- If your CPU cooler is not yet installed, remove the motherboard’s heatsink retention module and place the 4x NM-APS4 grey plastic spacers over the threads of the motherboard’s backplate, following the instructions in the cooler’s manual.
- Once the offset mounting bars are securely attached to the backplate, proceed by applying thermal paste and installing the cooler to the mounting bars, following the instructions provided in the cooler’s manual.
Note: The NOCTUA NM-APS4 grey plastic spacers and NM-ALS1 long screws are not included in the installation kit. Please refer to the cooler’s manual for further instructions on obtaining and using these parts.
