Fan going full blast after battery and fan replacement
Replaced battery and fan on my mid 2009 13" Macbook Pro.
On first startup fan went on full speed, and stays there.
Tried SMC and PRAM reset, unplugged/replugged battery and fan, still same problem.
iStat reports fan speed 0rpm when it`s running full blast, temperatures on cpu reports normal.
Is this a good question?
