They don't have what I need, unfortunately.

They carry a couple of nice Scythe fluid bearing fans which are supposed to
be nearly silent and last for many years, but I cannot find a Scythe fan that
runs at high amp/rpm.

The primary problem is that the vast majority of 120 mm fans on the market
are designed for computer and electronic equipment cases, and designed to be
quiet and run at fairly low rpm.

A power supply fan usually needs a higher amp/rpm rating because of the heat,
but they are nowhere near as popular, so it is harder to find them in the
noise.
