    That's a good question I don't know the answer to. I don't think it can be 8% above minimum because there's no definition for minimum psu fan speed in the tc tables

    I don't. It would be easy to do with something like Python

    @Necrotyr in tc, there is a 1232 byte array of tables starting with the bytes 10 17 F1 80 repeated 3 times, containing 22, 56 byte tables within each table, the 27th byte (zero indexed) represents the min chassis fan speed and the 31st the min spline fan speed. if you change the 27th byte in...

    The last 8 bytes vary across elfs on the 6018 - that one is correct for hwd. Original post edited to remove last 8

    Coincidence. I edited the post above with the probable tc table for the 6018

    @Necrotyr are you the user who wrote up the Noctua PWM mod originally with username necr? If it is you, I messaged you this info in 2018

    That makes a huge difference - the patterns are only valid for the SX6012 :) Here's the table for the SX6108 hwd + health: 00 00 00 1C 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 12 00 00 00 00 00 01 00 00 00 08 00 00 00 1E 00...

    Did you patch all instances of the byte sequence? In 3.6.6106, you only needed to patch hwd & health but I haven't tested earlier builds. To be safe, patch all instances in all elfs in that folder. The tc byte sequence only exists in tc but there might be several instances within that file

    Possibly a stupid question - did you reboot afterwards?

    Assuming the max rpm is the same in 3.6.1002 (13,000RPM for the psu and 18,000RPM for the chassis), you should be substituting 32C8 and 4650 with your chosen maximum. That area looks feasible - try it.
