My thoughts exactly!

In my experience putting the fan inside the case reduces the noise way better than pwm does.

Actually I've started writing a soft-pwm daemon but given up on it once I figured it's taking too much effort for smth I don't even need :-)

I've used a stochastic approach to this issue :-)

There's a 14% chance that the fan will start at 56°C. Then the probability goes up linearly with CPU/GPU temperature until it hits 100% at 62°C. And symmetrically the probability of the fan stopping goes from 0% to 100% with the temperature dropping from 54°C to  47°C.

Did it on a whim but works surprisingly well for me :-)
