I just installed my new PC and observed some parts on the motherboard getting very hot. I’m trying to figure out what went wrong. My motherboard model is the ROG Strix B550-F Gaming WiFi II.

The VRM, which transforms 12V to the required low-voltage levels for the CPU, isn't perfectly efficient and generates heat. That warmth needs a way to dissipate. The key parts of the setup are called MOSFETs, built to operate reliably between 125-150°C. Most motherboard makers ensure proper heatsink design and layout to keep temperatures between 100-110°C. This prevents damage over thousands of hours, especially since exceeding 100°C can harm the circuit board. In your scenario, Asus likely set a safe limit around 95°C, which explains the observed temperature range of 93-94°C. Operating within this range is safe; using a standard fan above the heatsinks should further lower the temperature.
