Yeah I would say try new fans in that case.

Trackpad cable has corrosion on connector, do you think it affects the fan ? not sure if trackpad and keyboard communicate each other on this model. Both fans look perfect.

Trackpad has temp sensor embedded, Palm Rest sensor...

Ok Ill try to replace trackpad cable first.

Ok after replacing Usb Controller chip (DONOR BOARD) its powering up. Fan didnt work due trackpad cable with corrosion. Clean and re-solder pins on connector fan spinning and now is a happy MacBook. Thank you guys. SOLVED.

Nice job! Just learned something new too with the trackpad issue.

Really strange, older Macs get max fan if palm rest sensor is not correctly detected.
If possible, someone with similar machine, to remove trackpad and check if fan doesn't really spin.
That will be good feedback...
