is overheating while the laptop charging dangerous?
Of course it is dangerous. Any electronics that "over" heat can be dangerous. But without know actual temps, we don't know how hot it actually is. You seriously cannot touch it without getting burned, there's a serious problem.
Unless you buy a really good cooler i assume?
the cost is usually so expensive like 500 quid whereas others t's like 50 quid ahhhhh, am i looking in the right place lol?? i don't know what the price should be i'm legit so confused
I have no clue what you are talking about here. I have never seen any cooler cost 500 quid. And I am not aware of any aftermarket replacement coolers for laptops. There are
laptop cooling pads which I recommend. But note I only recommend those with their own power supply. Many get their power from the notebook's USB port and that just puts more demand on the notebook.
