Fan goes nuts everytime I turn it on...
I have two A1342 Macbooks. One has a fan that spins up like crazy everytime I turn it on and it never shuts off. That one is otherwise normal. The other is fully functional with no issues.
The fan thing was really bothering me. I tried swapping the fans between the two macbooks and that didn't help. I even tried swapping logic boards, superdrives, batteries... everything.
No matter what combination of parts I use, the one has a fan that spins like crazy and the other functions normally. How is this possible?
I'm pretty much stumped and any insight would appreciated.
Is this a good question?
