I wonder if anyone could suggest a way to slow down the
power supply's fan. The fan runs too fast, the case is resonating,
too noisy.
Any suggestions?

Particularly since today's system boards run HOT, and most cheap PC fans barely keep them cool, let alone a box full of expansion cards. Besides, the fan is probably an AC motor whose speed is determined by the frequency of the line current (i.e. 60 Hz). If case alignment isn't the problem, put the box on the floor!
