That's total overkill on the fan, though maybe 40% is the default LOWEST setting?
As said you can setup your own fan setting.
Not sure if you have the option to DISABLE it, however the THROTTLE point that Pascal usually is set to is 82degC. Basically setup a suitable fan profile of dropping the fan to its LOWEST SPEED and ramp accordingly.
*use a benchmark like Unigine Heaven or similar running for several minutes to set the ramp curve. Maybe set LOWEST RAMP until roughly 60degC then start ramping up and set the MAX RPM at whatever keeps the temp below roughly 80degC.
I suspect your cooling is such that even 40% max RPM may be sufficient for that but you'll see.
(and if you can disable then just adjust the ramp accordingly such as 0RPM until 60degC then jump to lowest RPM and ramp up.
