How to Replace the Fan in a Dell E1705
The Dell Inspiron E1705 laptop is equipped with either one or two fans for keeping the system cool. All E1705s have a fan to cool the microprocessor. The second fan, which isn't available in all E1705s, is the video-card cooling fan. Both fans are easy to replace, although you must disassemble the computer halfway to reach them. Fortunately, it's not difficult to take apart the computer.
