Emissions from Legion Y730 with disabled GPU

[ulrik]

I'm considering the new Lenovo Legion Y730, despite that I don't need discrete graphics.

It is often reviewed for gaming, but I wonder:

1. How are the noise and heat emissions with idle/disabled GPU, but heavily loaded CPU?

2. Is there a BIOS setting for disabling the discrete Nvidia graphics?

3. Is the fan speed increasing and decreasing slowly or suddenly? Are there fluctuations in fan RPM, e.g. when idle and opening a web browser?

4. Are there BIOS settings for controlling the fans? If so, what parameters can be controlled?

5. Are there high pitch sounds from the fans?

6. Is your answer based on experience of the 15" or 17" variant? Which CPU? Windows or Linux?

Thanks
