Re: XPS-15-9570 (Bios 1.7) -
Short video clip of the issue. SreejithR asked for it yesterday
In this clip I put my phone as a microphone near the fan. So it is easier to hear it. The mic on my camera doesn't pick up the sound well.
In real life it is not too loud. It is like the loweset setting of the fan. The issue is just that it is constantly switching on and off, therefore it is much more obtrusive.
EDIT: On the left side near the WIFI symbol in the tray, you can see the when the nvidia card is active. That info is from the nvidia control panel. The blue temperature is for CPU and the green for the nvidia card. It shows zero when in idle mode.
