Laptop cpu drops extremely while playing?

Hi, I currently have the problem that my laptop gets super hot and therefore my CPU sinks extremely. Does anyone have an idea how to avoid this (p.s I already cleaned my laptop from the inside)

Laptop: ideapad l340 maybe someone has the same and knows a solution.

Thanks in advance

Unfortunately, laptops generally have the problem that the casing simply does not allow the heat to go anywhere. As a result, most laptops are often inferior to a PC or simply much more expensive.

What you can do is get a laptop cooler, with ventilation - which you place under your device. Otherwise replace the thermal paste.
