Answer to: Broken fan power lead to logic boardEd, The Circuit Writer Pen is the exact one I used. Positioning the chip is a bit tricky. Depending how the pins broke, will determine how easy/hard it is to get it back in the exact position. Take your time. I used the point of a scalpel blade to hold it in place while applying the glue. You could try something like blue tack on one side, while you glue the other, then once its set you could glue the opposite side. Applying the silver will complete the circuit, but it is tricky, I did it once (as mentioned above) then ended up wiping it all off and starting again. It is best to do it in stages. I used the point of a needle/pin to apply it the 2nd time. You want to avoid bridging the pins. I highly recommend a magnifying glass and lots of light. To be honest, I think I may end up trying to solder it. The idea seemed pretty scary to me, but after watching this video it doesn't seem too hard: http://store.curiousinventor.com/guides/... If you're not confident doing that, maybe just call your local electronics r...
Answer to: Broken fan power lead to logic boardI managed to repair mine. Buy yourself a silver conductive pen and some 2 part epoxy glue. Mix equal parts of glue together and use a wooden skewer to apply to the plastic connector. I had the connector sitting in the right place and just held it down while applying glue along the sides on the bottom edges. Wait for the glue to dry. Then I used the silver conductive pen and made a small puddle on my desk and used another skewer to apply the silver to the 4 pins. This isn't easy and takes time. You want to avoid using too much silver in one go. You may end up with 2 pins connected. So far my fan works fine althou I still can't get a speed reading for it using smcFanControl. Ps sorry for the crap formatting. Typed it on a phone.
