Last time I changed the fans, I didn't do it at home. I asked a repairing center to do it for me. They claimed that they had also replaced the computer's "power supply" with a new one. But to be honest, I'm not sure if they have done what they claim. Computer repairmen are very infamous in my country. They are known for making false claims to charge more money. And there is nothing one can legally do against them if such things happen. (I just noticed that they have fastened one of the wires of the CPU fan to its socket by using liquid glue!! The socket had been loose and they had not even bothered to change it; instead, they have used liquid glue.)

One of my good friends is a computer engineer, but unfortunately he is currently on a long journey. I think the best I can do is to wait for his return and to ask him to see what can be done. (I just hope the liquid glue will resist long enough.)
