Solved! VAIO laptop shuts down suddenly and overheats while playing game

Apr 7, 2018
I have a VAIO laptop, and whenever I try to play Fortnite on it, it runs well for 15 minutes or so, following which it suddenly shuts down and is overheated.... Could using a CPU fan solve the problem?
How old is this VAIO laptop? When was the last time the dust was cleaned out of the fan(s)? The thermal paste on the GPU and CPU might also be dried out and need replacing.
