My coil whine is present since the first boot and without any tweaks or cpu load...you have the same i7 8750H cpu?
Can you please check your cpu clocks in aida64? In aida64 go to computer -> overclock and see what the clock speed is while idle and then run the stress test in aida and see what the clock speed is then
As i mentioned in my thread on my notebook something isn't right, the idle clock is cca 4GHz instead of 2.2GHz and the full load clock is 2.2GHz
And did windows update your bios to 306?
