Fans, fans, fans

on 2011 macbook pro (13.3" i5), fan speeds sped 6100rpm , stayed there.

temps within normal limits. fans running fast, full charge on battery lasted 2 hours.

sent apple. replaced logic board , heat sink.

now, fan speeds go approx. 4100 rpm , stay there.

cpu temp around 76-77c

3 base temps running @ 31c

heat sink 53c

memory module around 50c

fan running not change of temps.

needless say, reduces life of battery charge, significantly. maybe 3 hours out of charge...

got ideas?????

@ least less noisy @ 4100 @ 6100

 

have tried smc reset yet?
