820-3332 shipped to me with previous repair work and bad u8900 soldering.
Sorted out u8900, cleaned flux in the ultrasonic. But the thing will not stop running fast fans despite passing apple internal hardware test. Ive checked HW monitor also and found all temperature sensors reading correctly, none are stuck .ect

The fans will start ramping up if left in boot menu.
Tried a known good shell and TPAD cable, tried new SMC, tried new EFI with clean ME region. I still have the same problem, Should i try ASD EFI on it just encase HW monitor and Apple hardware test is not picking up on the the issue?

Problem resolved.
Turns out it was EFI related and i just did a terrible job at reballing a replacement SMC leading to a different thermal sensor issue. Lesson learnt, Retest after every repair attempt just encase.
Thanks
