EDiT:
CPU Whine SOLVED: (kinda)
by Whyte1) open regedit
2) navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\ PowerSettings
and search for 5d76a2ca-e8c0-402f-a133-2158492d58ad (CTRL-F to search)
3) double click Attributes and change the value from 1 to 0.
4) now right click on the power icon in the tray, go to Power Options,
5) click on change plan settings for your plan, then click on Change advanced power settings,
6) scroll down to Processor power management and you should see a setting called Processor idle disable, change it to "Disable idle". Click on Apply.
The Whine disappears! But there are consequences.. "With Procesor idle disabled, your CPU is going to run a lot hotter and comsume a lot more power."
My CPU and GPU went up 5degrees celcius instantly.. and stabled at around a 10degrees increase.. hmm..
