I got my new G750 JH yesterday, it ran fine without making any noise for the first time i launched. I even played DOTA2 on steam for more than couple of hours and i didnt notice any noise.
Today when i use it without any programs running on it, yet it makes considerable amount of noise on the left fan. And right one doesnt even feel like running at all. I tried restarting as well, it didnt help it.
I have also tried to change the power mode from 'Power4Gear' to 'Balanced' which reduced the fan noise a bit. Is this kind of expected thing? Because i have read lot of reviews before buying, which said this machine is very quiet.
