Sapphire Radeon Vega 56 Pulse fan speed

Hi folks,

This topic is very well covered all over the internet, but I have been unable to find a fix. 2 minutes after startup, my GPU fans ramp up to 49% duty, ~2400rpm and seem to be locked there. It's very loud. So far I've tried:

• Tried configuring a bunch of different settings in VGTab and putting the VegaTab kext in Clover/kexts/Other.
• Tried removing the kext and configuring the Clover/Devices manually like in the screenshot below.
• Tried using RadeonVegaLowFanSpeed.kext
• Looking for a copy of AMD10000 kext now but not holding out much hope that it'll work.

It seems that the Pulse model of the card is a non-reference card, which is why these fixes don't work. Any ideas?

Manual device configuration

Cheers,
Alex
