Repairing the Asus B202 CPU-fan

After about three years yesterday my trusty Asus EeePC B202 Box which runs my Windows Server 2008 x86 started to make terrible noise. The failure was quickly located: the CPU-fan! When I moved the box around it was silent as usual. But when it was stable it was making loud noise. So the bearings needed some oil obviously.

I decided to disassemble the box to get to the fan, that was not so easy as I thouight it would be:

1. Take out the HDD and remove the 2 outer screws
2. Remove the plastic cover carefully as if you would replace the RAM.
3. Remove the s4 crews in the corners that hold the plastic frame.
4. Remove the plastic frame very carefully from the front to the back. There are notches to hold it in place. Pull the black tape first, so the power button would remove through the cover slit.
5. Remove the remaining plastic back cover
6. Remove the 4 side screws
7. Remove the 2 top screws. Peel off the first, flat metal cover.
8. Open then WLAN opening (1 screw) and remove the connector in the corner-side (if the opening is left/bottom, remove the left one!)
9. Flip the motherboard over and remove the remaining screws.
10. Remove the metall cover from the back to the front this time. Watch the power LED. Some metal case parts remain on the motherbaord. You need not to remove them.
11. Peel off the tape that covers fan and heat sink.
12. Remove the 2 fan srews. disconnect the fan-power.
13. Remove the fan from the motherboard. it is a Delta Elektronics OEM fan BDB05405HHB (5V 0.36Watts) which is hard to get.
14. Remove the very small fan screw, that holds the metal cover and than open the clamps to remove the metal cover of the fan.
15. Now you see the fan. Clean it with pressured air carefully.
16. Pull the blades from the motor by carefully gripping the fan-blades in 180 degree with thumb and pointing finger and pulling them firmly but carefully straight up. Do not bend or otherwise tork the axle.
17. Now get some oil (I took the oil from my electric shaver) and a needle. Tip the needle in the oil and bring the sticking oil to the axel ijn the fan blades housing. Do not put it in the motor directly! Use only a very tiny bit of oil. The small drop i sused was even to much!
18. Now press the fan-blades back into the fan motor. and turn them a little bit. You can also use the presured air to drive the turbine  The oil should now we where it supposed to be.
19. No reassemble the B202 in reverse order(14 to 1).

If you have put the motherboard together without the plastic case you could make a first test (5 to 6). The fan should make no noise now. The wild at hard can do it even before step 10.

I had to nstart the B202 twice to get it to run and it lost the RTC settings so it was back to 10.10.2010 (???). But now it is as quiet as on day one.
