I recently bought a new Asus Zenbook laptop and I notice it has slight coil while(sounds like Morse code) from the cpu and medium to light loads(watching a movie). If I run prime95 or something that uses a lot of the cpu the whine goes away after a few seconds. It not really loud but it can be annoying to hear sometimes Will this whine eventually go away? Should I just tolerate it or RMA and hope the new one doesn't have the same(or worse) problem?

CPU: i7-8550U Processor 1.8GHz
512GB SATA M.2 Solid State Drive
2GB NVIDIA GeForce MX150 Graphics

Also I disabled the MX150 just to make sure it wasn't that.

Thank you

There's no reason to expect that the twitters or beeps from coil whine will ever improve, so if it's audible enough to be an irritation, I'd get it dealt with now. If a replacement was the same or worse, then the dilemma would be to try establishing whether it's a design or batch fault. Hopefully that won't happen!
