How to Fix Opencore 0.6.7 CPU fan louder?

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Check if your GPU requires WhateverGreen or specific boot-args (e.g., agdpmod=pikera).
  2. Ensure Metal acceleration is fully supported for your macOS version.
  3. Update Lilu and WhateverGreen to the latest versions.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

Is this just me having a placebo effect? Anyone running into an issue where their CPU fan is running a bit faster / louder on OpenCore 6.7 vs 6.6? I'm on a AsRock x570-Phantom Gaming 4 running latest Big Sur, Ryzen 3900, RX5600XT with a NZXT watercooling setup. I swear the fan is maybe 20% louder at idle after I just updated the EFI.

edit: yeah the more I hear it, it's definitely louder...
