I hadn't considered that, thanks.

The manual says this.
"... a fan with a 3-pin connector can be used. However, since the
fan with a 3-pin connector cannot use the onboard fan control, the
fan will always operate at full speed."

So, I severed the fan speed control wire (the fourth wire) and the fan
speed is now almost double at 1975.

I guess that's full speed, but if not, maybe the fan speed sensor lead
can be left attached to the CPU fan header (by simply severing all but
that fan speed sensor lead) and just the V+ and V- leads can come
directly from the power supply.
