Recently, my laptops fans started making a grinding noise, similar to that of an electrical shaving machine. It starts and stops at random times (especially whenever i turn on the computer, or randomly when playing games)

PS: Air does come out of the laptop, only that its hotter than usual (i already tried cleaning the laptop of dust, ending unnecesary programs, unninstalling programs and i even did a virus scan, but to no use).
