I am using Dell studio 1555. Normally I use my laptop fir web browsing. I never do any experiment with my laptop as I donít know much about it. I only use my laptop for my work from last 5 or 6 days I am facing some problem. My laptop fan start making noise after one to one and half hours. I donít know what is wrong with my laptop but whenever fan start making noise it really irritates and I found very difficult to work with that kind of noise. Is it possible to change the laptop FAN? Please suggest me some solution for this.
