Give this kext a try to see if it helps with the Vega 64. If not, remove it.

I tried the LowFanSpeed Kext you attached and it is the only solution that lets my fans spin down again after load (Gigabyte Vega 64 Gaming OC / High Sierra 10.13.6). But there is a problem: It only lets one fan spin, the other fan stays off. Do you have any solution for that?

I can't recall if I posted this on the X99 thread or this one, but everyone here knows they can use this utility to custom generate a kext for their Vega (Vega only!) and fine tune it to whatever they want? (and yes, I used it to generate a kext and it seems to work just fine). Note it requires Safari....

As always, if you have an existing working system, before you insert a kext from this utility into your EF\Others folder, you absolutely must consider any other kexts or aml files you may already have installed. You have to be concerned about conflicts. So, if you use it, and generate a kext, be thoughtful and implement with care.

So, I saw this utility on an Asian site and it was all in Chinese. Then I saw it posted here (still in Chinese) and someone translated it to English, for the life of me I can't find the user who did that, but thats' where it came from.

@kgp I apologize if this is a duplicate post.....

@mm2margaret I tried everything out there already. The initial problem with my Vega 64 Gaming OC was that the fans spin up a minute after boot without any load. I then got rid of that issue by updating the cards BIOS to the latest version from Windows. The card remained silent from then. However, when putting it under load, fans do spin up and then fail to spin down. The often mentioned workaround of opening a video file to get the fans to spin down doesn't work on my card. Only a reboot works.

I also tried the VGTab-App with numerous settings. But never had any luck with it. It either resulted in the fans not turning on at all (= crash due to overheating) or the fans spinning up as usual and never spinning down again. Might be that I am just using it wrong tho.

The LowFanSpeed Kext I sourced from this topic (page #801) so far has been the only solution that managed to get my fans to spin down after load. However, as mentioned in my last message, only one fan of the two fans spins up which results in the card getting pretty hot and the fans taking longer to spin down after load. The other fan stands completely still, not a single sign of movement.

So, you can try this thread on insanelymac: https://www.insanelymac.com/forum/topic/325120-vega-frontier-edition-on-high-sierra/. There are a bunch of Vega kext posts there. Maybe one will work for you.....

This problem of spin up and failing to spin down is common with the Vegas running on a Mac. I think even Stork mentioned that with a real iMac Pro the fans can get quite loud when pushed. My Vega did that too (not spinning down after getting hot), but after trying a few kexts, I finally found one that worked (although it still takes a long time to spin down - but it does eventually), and with the utility, I managed to produce one that works even better.

So to use VGA Tab, the utility i've been discussing, you can't use the complete aml that KGP has constructed. You have to exclude the section on the Vega, or it won't work. That suggest some kind of modularity must be accomplished. Maybe you can delete the Vega PP_PowerTable section, or you can adjust it so the PP_Power table is not used or does not affect the results. What I do is to use modular aml files, created for each individual section of the guide, as opposed to the "one aml to rule them all"....approach. The one aml file is not a bad thing, it's just a different approach, understand?

I've been told by many that this issue appears to be finally addressed in Mojave. Something to think about, as Mojave is not far around the bend, and will be released soon. @kgp has already started a thread. Maybe you should check it out!

It should be lower than 120W if you let the display(s) sleep...
That’s what my UPS shows, the screen isn’t even plugged on the UPS.

BTW, my Bluetooth usb dongle works perfectly, I disabled the USB port attached to the built-in BT. haven’t tested with the Magic Trackpad as I don’t have it here.
Do you know if there’s a way to have both BT adapter working at the same time? So I would have the trackpad linked with the Broadcom BT card, and the headset with the USB dongle.

Found plenty of ways o switch between the two, but only one works at a time.

Hm that's odd...mine is bout 80-100W on the PSU on idle with monitors off. Which is the equivalent to about 3-4 low powered light bulbs. It must not cost more than $20-30 per month (USD) on my end for idle.

Yeah the USB dongle will work better than onboard BT modules, including OSXWIFI (from my personal experience).

The downside is you cannot use that USB dongle with a wireless trackpad/keyboard/mouse during BIOS, it has to boot into an OS first.

Unlike OSXWIFI, which lets you have access to BT in BIOS.

I don't think you can mix USB dongles and have a good time. If it shows up under Bluetooth in Sys Info then I guess it's probable that it's working?

I just personally had issues with OSXWIFI + BT USB Dongle. I was trying to use the BT USB dongle only for audio and OSXWIFI BT for other stuff (incl wifi).
