Razer Core X Thunderbolt 3

From the product page, it seems the NITRO+ Vega cards has a different fan management system than most. One thing you can check quickly is the connect the Razer Core X fan to the 4-pin PWM header on the card. My guess it that it won't run. I'd recommend checking with Sapphire support for assistance. Also try both vBIOS and see if that makes a difference.

Rather than hunting and searching the forum, gettting old info or getting the wrong direction. Can you share a link for vBIOS haven’t seen or heard of that one.

by the way... thanks for the fast reply!

I have a Sonnet Breakaway Box 550 with a Radeon RX 570 and I don't have any fans on in MacOS either.

The vBIOS switch is on top of the GPU near the mounting bracket.

Hi DJMic you can edit the info.plist in the good kext (system/library/extensions/AMD10000controller.kext) and use a soft power table editor to change some setting of the card without flashing a new bios.
Before I have got this problem too and without fans my custom watercooling vega strix 64 was going to 70°c, now i have an iddle temp of 28°c with the fans at 700 rpm and in load my card doesn't go more than 48°c with fans at 2000 rpm.
I give you a link in an external forum of hackintosh which explain all of the things and its work for egpu user too, at the end of the thread you can show what settings work for me.

Can I ask you what "soft power table editor" is on the Mac?

Its only in windows side but you can make the soft power table in it and import it in mac os.

Would "TextWrangler" for Mac work for editing the AMD10000controller.kext file?
Never mind after reading the GitHub info it looks like this is a specific editor in Windows for the kext file.

You wouldn't know what ideal settings i should put in for this particular setup on Mac with eGPU?
