Recently i've ran into the problem that my laptop had collected too much dust inside and starts overheating in difficult tasks (i.e. games), this happens every half a year or so, as always i opened it, cleaned the fan with the air duster, and put everything back together.
So i thought i'd test everything and the problem became even worse, it is now overheating even while watching movies. the fan is definitely still working i can hear it spinning inside, and i can feel the COOL air coming out of the side of the laptop, where the fan is located, while the middle of the laptop where the cpu and gpu are located becomes really hot.
Is there anything i can do to fix this? would buying a new fan help?
Model is: Acer aspire 5742G
Thanks in advance for any kind of help
EDIT: I've found out what the problem was, turns out there was a little piece stuck inside the fan which prevented it from rotating at full speed, which i only discovered after taking the laptop apart again.
