Hi!
If it is still covered by a warranty, I strongly advise that you let the service center handle the case to make sure of technical assistance you needed even if they have replaced your cooling system. The fact that the problem recurred, the technical solution provided was not addressed. This could be a manufacturer's defect which was not monitored since you only used your computer for three months. This is the best approach to your problem if your unit is still under warranty.
Otherwise, you consider the following, but still advise technician to do the job for you if you do not have the technical knowledge:
1. Check the air vents.
a. Check the vents to see if it is dusty. Dust blocks passage causing heat increase
b. Shutdown your unit;
c. Disconnect the power cord from the electrical outlet.
