Okay, I'll bite. What are hydraulic bearings?

This is a quote. Hydraulic bearing has larger oil storage space than sleeve bearing, and has a unique oil supply circuit of loop type. As its bottom is sealed completely, the lifetime is longer than that of sleeve bearing. It is suitable for high, medium, and low-speed fans. The average life of hydraulic bearings is 40000-50000 hours.

What is the hole pattern (and other dimensions) for these fans?

(3) 3.85 mm Diameter mounting holes. 35 mm apart. 12.85 mm is the length of the screw holes. Exit hole is 16.55 x 24.80 mm

What is the connector type?

JST Male 2.0 mm spacing between wires. Must be 2.0 there are a few more spacings.

I ordered jst 2.0 female connectors for these fans and they are too small. anyone have a link to the correct size female connector?

You need 2pin JST XH2.54 MALE type connector.
