Some people are just hyper-sensitive to noise, heat, glossy screens, etc.... I understand that.
Reminds me of when I was growing up my Dad had an automotive repair shop. People would come in and say my car is going tic, tic, tic or some other normal engine sound. He could have said for $2,000.00 I can fix that. But, as most were friends and long time clients he would tell them to Turn the Radio up. 😎
So, Pop some noise-cancelling ear-buds in and go about your business..... Listen to a little Mozart while you work.
Or, pay a few thousand for a new computer....
