100% fan the pc turns off after 5 minutes or less

[Respawner76]

Hello
here is the problem
I have a laptop samsung np-r720h with new thermal pasta and without screen (I have to change soon). The pc turns on, windows starts, then the fans start turning louder and the pc turns off. I specify that the pc does not even have time to heat.
can you help me?
I'm French sorry for my english ...

Probably the fan/cooler is not installed correctly. Fan connected correctly?

It can heat up very quickly
