just to throw it out there, I just realized last week that if you upload the mass airflow sensor the fans come in max.

and the stay on for a while. some kinda air temp reading in the scanner slowly reset and it fans turned off.

no clue if yours is the same. you might need a decent scanner to find what's requesting the fans on.
