Hi, My MacBook's fan failed and I am trying to get one from e-bay. It is an old A1181 model. However there are couple of different models for A1181, so I need to be %100 sure before ordering it. Could you check the images I have attached and help me to understand if both images belong to the same model. (I am %80 sure that they are.) There will be slight differences between two, however the most important part is the e-bay description: "DESCRIPTION: THE FAN HAS A 4 PIN BLOCK HEAD CONNECTOR TYPE & THE HEAT SINK HAS 2 CONNECTORS WHICH ARE THE 2 PIN FLAT HEAD TYPE (NOT BLOCK HEAD)" (The fan with the "SUNON" brand on is my original one dead fan / heatsink) Thanks.
