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.
Any ideas.?
Is this a good question?

Who's Fan did you use? Did it mess up the SMC services?
You may want to take a look at the temperature section are any of them high (wrong)? If not you may have a pinched or damaged the fan cable or the new fan is also bad.

I used the OEM fan from iFixit, replaced it as the old one was a bit noisy.
Tried replacing the fan with the old one and problem was gone.
New fan is going back to ifixit. Thx for the reply.
