Hi, I have a computer since 2 years. It is an assembled Intel Celeron D345, 3066 MHZ. My CPU fan starts creating noise almost every 2 months. The first fan lasted around 10 months but over the last year I have been changing a fan every couple of months. Noise starts, then temperature going above 70 C. At one instance the computer was shutting down due to overheating. The noise completely disappears after I replace the FAN but for two months. Can you please tell me how can I resolve this problem for good. The FAN type I get is the only one available in the market.
