To prevent abnormal CPU heating due to incorrect assembly of the CPU radiator, which can lead to system instability or crashes, ensure the following steps are observed during assembly:   1. Applying thermal paste: a. Ensure even application of thermal paste. b. Follow the application instructions in the CPU cooler's user manual.   2. Installing the CPU cooler: a. Consult the CPU cooler's manual for proper installation guidance. b. Once installed, verify that the radiator is not tilted and the thermal paste has not spilled over. If either issue is present, reinstall the CPU radiator.   For the installation of the CPU radiator, refer to the motherboard's user manual. This manual will detail the complete installation process for the radiator. For instance, for the ProArt Z790-CREATOR WIFI motherboard, the installation can be found on pages 2-3 of the user manual.   T20704_ProArt_Z790-CREATOR_WIFI_WEB.pdf (asus.com)
