Suddenly I got into the summer holidays. My pc is getting very loud (it sounds like my psu) is this normal due to the weather / heat or it is breaking?
That's not entirely true. It is a tried and tested method I have applied and my fellow colleagues have as well. Laptops are strongly built and the chances to damage any part is nominal. In majority of the cases it doesn't affectNote: You should never blow 'into' a laptop from the vents. This can cause more damage than you started with.
