Fans work in sleep mode

[nofirg]

Thx for publish your project, it help me to run MacOS on my i7-3820 + MB E5 3.5b
Could you please give me advice or forward me to right direction.
I have problem with sleep mode: when computer going to sleep, fans still work in usual mode, only display switch to sleep mode. I suppose it can be fixed by enable s3 power mode, but I have no that option in my bios, only s1. Does it right thought? If yes, can I fix it by dsdt patch or may be modify bios rom?

no S3 power mode support on this motherboard

And its main and irreparable reason sleep issue?

[ichswarox]

Yes, because huanan mother board not support S3 power management.
S1 - Stand By (Power On Suspend) - no system context is lost
S2 - Stand By - CPU and system cache context is lost
S3 - Stand By (Suspend to Ram) - system memory context is maintained, all other system context is lost

It's so sorry.
May be you know, this power management hardware or software implementation? May be it's possible to fool the system

S3 status of sleep requires BIOS/UEFI modification, and this is one of the hardest part of most X79 mobos which i haven't found a way out.
