    Hi, has anyone developed a config for Notebook Fan Control that works with the Vaio VPC-E series of notebooks?

    I have tried the existing configs that come with NBFC but none of them work. I have also tried making my own but haven't had any luck so far.

    I've attached an image from the NBFC EC probe tool which recorded the EC with the fans being stressed from low to high to low and the DSDT is uploaded here: https://pastebin.com/U91YW53B

    I'd really appreciate any help with identifying the read/write register(s) and any register for manual mode, if it is needed. My notebook model is VPCEB4C5E. Thanks in advance.

    I manually stopped the fan and the registers that went to zero were 70 [0x46] and 71 [0x47] so I assume these are the fan control registers. Unfortunately NBFC does not seem to work with these registers even with the poll interval reduced so I guess the Embedded Controller needs to be put into manual mode. Can anyone give any advice as to how to find the correct register that puts the EC into manual mode?
