Hi, so I've been using this laptop for few weeks now, and one thing I've recently noticed is the fan keeps turning on and off. It's not killing my battery. I undervolted it using Throttlestop, and it's been stable at -165 (haven't pushed it further). I've also overclocked the GPU, when I game. Otherwise it's set at standard clock.

I did notice, however, the fan turning on and off, and I'm looking at my GPU usage, and it just seems to flip on and off. Any ideas as to what's going on?
