Power Supply Fan Direction

That does not make sense. Why would you want to force all that heat onto your electronics? You really want to suck it all out of the computer as it is the only fan in the machine.

You can safely switch directions on a 2 wire (only), fan by swapping wires. Make sure the front is correct for direction.

Nope. Most of them are electronically commuted, i.e. by a small chip in the fan. The electronics requires the power supply exactly in the specified direction. The only way how to reverse a DC brushless fan is just to install it the other way around.

Brushless motors are 3 wire,usually 1 more for speed sensing. I specify 2 wire only because of this.

All fans are marked (with arrows) to tell which way they rotate and which way the airflow is.

Yup, The fan itself is an airfoil designed for blowing in 1 direction only and very efficient at it.
