Comment 44 for bug 1602888

I have just tried simply removing the bottom cover and holding the laptop against an electric fan. And the fans stopped spinning.

I had to run several applications and execute a heavy task to re-trigger the fans. Fans start at max speed for a few seconds and then settle down at typical low speed.
I was able to repeat and confirm this fan response.

It seems the fans are configured to stop only at very very low temperatures.
