Hi. I finished recently my hackintosh build with Sierra. I followed this guide: https://www.tonymacx86.com/threads/...s-viii-gene-i5-6600k-gigabyte-gtx-950.181272/. I am using my HD530 graphics using the patches from Skylake glitch fix.plist. And finally I have my SSDT for 6700k from here: https://www.tonymacx86.com/threads/guide-el-capitan-on-the-skylake-h170n-wifi.178197/#SSDT
Everything works perfectly except there is a high pitch noise under certain conditions which for now I couldn't hear on Windows 10. It happens right, after DSMOS has arrived, also if I install and application it happens after the install for a few seconds and then it stops. My plex server is on the the hackintosh if I watch a movie on my laptop through plex while it is playing I can hear the noises if I press backward or forward the noise is stronger. These are my specs:
Motherboard: Asus Z170-PRO
CPU: Intel Core i7 6700k
RAM: Corsair Vengeance LPX 32GB (2x16GB) DDR4 DRAM 3200MHz
PSU: FSP Blue Storm II 500W (quite old but haven't had problems with my old build)
The noise is really similar to this one at 4:27:

Thanks. I think I was able to identify that is the PSU. I have ordered a new one as this was really old.
This is mine under Sierra:
 
The issue was solved by replacing my PSU with RM650X as it is one of the approved PSUs from the buyers guide. It is dead quiet now.
