laptop over heating ( Aspire F5-573G )

ARUH

Hi

My laptop ( Aspire F5-573G ) fan was making a lot of noise as if something was stuck inside it and i was afraid it will stop working suddenly.

I took it to a repair shop and they replaced the fan with a new one, and he did apply the thermal paste on the processor and gpu.

I noticed the when i play some games it gets too hot, i think hotter than usual.

i tried some software to give reading of the CPU, and it reaches 100 C while playing . Unfortunately I don't recall the temperatures before changing the fan.

1- Could this be due to a bad fan type? wrong installation?

2- Should I worry about these temperatures?

3- Few days ago, the Left Shift key with not respond most of the times. Could this be related to the heat starting to corrupt the keyboard? i tried taking the shift key out and cleaning a bit with no luck.
