It all depends on the amount of work being done by the fan.

Even if the fan is spinning faster, it may have a less aggressive blade profile that moves less air.

The less work the fan does, the less power it needs.

When a fan is started, it must overcome the inertia of its moving parts and may draw more power than its rating. This is "start-up-surge".

Watts is watts, the fans draw their rated draw (unless you're running them above or below their specified RPM or are measuring starting power).
CFM, on the other hand, is a flow-rate and is a better indicator of the amount of work being done.

Anyway, just connect all the fans to that splitter, connect that to a single 4-pin Molex and be done with it. You will need an adapter for that splitter or get a splitter terminated for 4-pin Molex.
