@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...
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
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.
