Are MBP A1150 and UMBP fans physically the same?
I have a A1150 MBP its old but does the job,
i replaced the screen with a 1680*1050 screen
but thew rest is stock
the mbp runs hot and the fans are half dead
they go to 3k rpm and make crunching noise (something is broken there)
i checked ebay and the fans look identical
but i read the connector is different
it not a problem to re-solder the connector
so the question is, are they PHYSICALLY the same?
ie the distance between the screws and the WHL dimensions
ps: i would just repalce them if i had a spare UMBP :)
also the price is about 10$ lower than the old fans
Not a direct answer to you question, though a direct answer to your problem. Peel back the paper on your fans and put a drop or 2 of 3-N-! oil in the exposed hole. Reseat the paper covering and/or put a piece of tape over the fan bearing. I have repaired hundreds of noisy computer/laptop fans this way.
