shutdown

Hey, for some reason my PC shuts down when I work under heavy load. Does anyone know why? I also did a log during the latest shutdown using hwinfo. I am not so much of an export, so maybe someone can figure something out from the log...

I have laptop it's Dell inspiron 15 5559 with one single fan. It's too slow so I decided to custom fan speed the fan 4900 rpm when i play games after a few minutes it keeps freezing and shutting down the temp and everything is normal that's the only issue, I just use for fan speed
