MP 1,1-5,1 Positive Pressure, or maximum air throughput

[mattspace]

Just wondering what folks think about customising fan speeds, whether it's better to have slightlt more air being pushed into the machine, than the rear fans pull out, which I believe can reduce dust ingress, or whether you want to get as much air out as possible to remove heat.

Anyone experimented with it?

My $0.02 says higher airflow equals better heat dissipation and that is the name of the game. Given that there are always electrostatic charges present, you will always get dust accumulation.

Unless you have N95 or HEPA filters on the intake fans, the dust is going to come in through the intake fans (for positive pressure) or case vents the same.

Worry about Covid19 instead.
