Today my fan started to make a lot of noise all of a sudden. I open it up and clean the dust but still making noise after. Only one fan is making noise. Where do I find a replacement fan and how do I do it. My warranty is over and I got the rz09-02705e75. Please help this is my only laptop and I don’t have a lot of money to buy new one. I need it for work too. Please help ASAP.
