HELP - Macbook Pro reflow - fans always fast

[Gurj1979]

Hi guys.

Just signed up.
Looking for serious help.

Has anybody got a solution for why Macbook Pro fans spin fast after reflow/reball ?

I use an Achi IR PRO SC machine for reflow and reballing.

I've had several different Macbooks Pros in for reglow and reballing but I can never seem to prevent the fans spinning fast after the repair.

Right now I'm working on a 2010 15" i5. Everything works...but the fan spins fast after a feeling seconds.

Thanks.
