How to Clean Laptop Fan and Apply Thermal Paste on CPU and GPU republished with permission by Analogue-Chick.
A few weeks ago I experienced a problem with Flash Player causing my laptop to shut down due to overheating as CPU usage spike at the utmost. I noticed the trend about Flash when I turned back on the system and opened a facebook game, especially for Firefox users. I then googled for similar cases and read a couple articles related to the problem, so I tried other browsers like Chrome and ended up with the same problem.
Although this does not answer the question why Flash Player causes overheating, this somehow reduced my average laptop temperature by 10-15 C down to a much comfortable level 45-50 C. What I did was I opened up my laptop, and cleaned out the air intake, fan, and heat sink then applied thermal paste on CPU and GPU.
So for this instructable, I'm going to show you how to apply thermal paste and clean your laptop fan. Although applying thermal paste is a very easy process, it should be done correctly, otherwise you will not receive the optimal cooling effect that is desired.
