Step 3

  • Using a plastic opening tool, pry the plastic casing away from the base of the computer, the remaining clips around the edges can be released using your hands.
  • Leave the side with the USB and audio port until last, then slide the case out and off, so the audio port doesn’t get caught.

Step 5

              Disconnect thermal sensor and power cables
  • Watch out for these two ridiculously fine wires. Carefully disconnect these with a pair of tweezers. Don’t pull on the wires to remove these.

Step 6

              Remove the fan and heatsink
  • Undo three bits of black tape holding down various wires connected to the fan and heatsink. Lift up the corner of the battery next to the outside of the case. Lift the corner of the fan so it’s above the corner of the battery (or you can just remove the battery altogether; that might be easier).
  • Carefully wiggle the heatsink out from under the taped wires. Remove the whole unit from the computer.

Step 7

              Replacing the fan
  • If you have ordered a completely new fan and heatsink, go directly to step 8.
  • The fan I ordered came without a heat sink, and contained the parts shown: fan body, thermal paste, screwdriver and a bit of foil tape.

Step 8

              Replacing the fan (cont'd)
  • In my case the new fan (right) had a bit of white adhesive tape here - not good - that’s going to collect every bit of dirt that goes through this fan!
  • So I snipped off some of the foil tape, and covered up the adhesive side of the white tape. Problem solved.

Step 10

              Preparing to install the new fan assembly
  • Thoroughly clean off the old thermal paste from the CPU and the heat sink. Apply a small amount of paste to the processor in the two spots that contact the heat sink.

Step 11

              Installing the fan and heat sink assembly
  • Reverse the procedure you used to remove the fan and heat sink. The thermal and power cables only go in one way. To avoid breaking these wires, I used tweezers to insert these connectors.

Step 12

              Last steps
  • Tighten the screws to affix the heat sink to CPU, and install the two screws that connect the fan to the case.
  • Put the case back together, power up and test. (I started a half dozen apps and within a half a minute the fan started up). I wasn’t completely happy with the new fan, as it isn’t completely silent but it was waaaay better than the old one.

Hi, exactly what I need ! Any advice where to buy the fan ? I’m in France

And I also need rubber feet and the little plastic cover for the second battery if you know where to find it.

I found few websites for the fan but I’m not sure of the quality. The price move from 10$ to 60$… And for the accessories, nothing.
