A1466 cooling fan stops working but works if external 5v is on.
Hello, after replacing keyboard and battery of A1466, there was no issue at first.
But eventually my fan does not rotate....(maybe a week later).
I have an arduino which can test cooling fan with valtage of 5v and ground.
After testing, there is no issue. The fan rotates, but not on the macbook.
There are also 5v, ground, and 3v out in 4 pins of fan connector of Logic board.
I did SMC reset..no work..macbook starts up but no fan running I wonder if cpu will be burned out when cooling fan does not work…
What happened to my fan? Do I need to buy new one?
Update (09/27/2019)
this is with fan
this is without fan
Update (09/26/2019)
it is 80 degrees but fan does not work…..

@jadelyly - Lets push the system a bit harder your temps are still low.

OK, not good!
Are you sure your fan is OK? Have you tried a second one?
You'll need to take the logic board out to inspect the back side for liquid damage around the SMC logic and/or damaged/missing components.
Do you have the skills and access to the needed parts to replace damaged or missing components? If not it might be easer just replacing the logic board.

@danj okay replacing logic board is too expensive..I will buy a new fan and test smc logic component with tester..if result is no good..I will say goodbye to my macbook..thanks anyway
