Hi, it seems like the program is falling back to smart mode as a safety measure under high temperature. By default the threshold is set at 78C, but you can increase it by changing the ManModeExit value to for example 98 in the TPFanControl.ini file. You can also change the ManFanSpeed value in the same file to change the default manual mode fan speed. For example, setting it to 80 would make the fan run at full speed. You also need to restart the program for the changes to come into effect

You can also change the fan curve for smart mode 1 in the TPFanControl.ini file, for example:

Level=60 0
Level=65 1
Level=75 3
Level=80 7
Level=90 80

means that for 60C, the fan runs at level 0; for 65C, the fan runs at level 1; ...; for 90C, the fan runs at level 80
