The video card's fan keeps running on and off constantly, even when I'm idling or doing nothing. I looked at the fan settings in NVidia Control Panel and am not really sure what setting I should put, whether Automatic or Manual. Any suggestions on what to set inside the Control Panel and how to set the fan to only run faster when the load is greater? Currently, it just seems to be running on and off randomly. I've checked the temps and everything is normal.
