Custom Fan Profile for RX580. Tested on Sapphrine Nitro+, Pulse models. May work on other RX580 models too.
This custom fan profile is injected, via OpenCore loading, to the Graphics card Device Properties, to achieve a faster fan speed. The default fan profile (stored in video card BIOS) does not start fan spinning until 60C and ram up too slow, so the card would be running a bit too hot under macOS.
This profile has the following parameters:
- Default fan speed = 20% (Fan will spin constantly at low RPM, by default)
- Med Temp = 60C (40% Fan Speed)
- High Temp = 70C (60% Fan Speed)
- Max Temp = 80C
- Target Temp = 70C
The additonal instruction to create your own fan profile can be found in this (link here).
