my pro has been sounding insanely loud lately especially playing MW.
opened it all up and my fan had some dust but nothing excessive, so presumed its the thermal paste, ordered some Decent paste, rubbing alcohol and the correct security driver and some canned air, and followed this guide. The stock paste was a joke, hardly any attall, took about 30 mins taking my time and really very easy to do.
The difference now is unbelievable, no noise whatsoever.
I just took photos of the areas I was removing screws from which was really helpful putting it back together.
