With all of the wires being clear(silver?) how can you tell which wires are +12V, Ground, and Other?

It will need to be tested for correct rotation so the blade spins & pushes air according to the arrow on one of the 4 sides of the housing. The wrong polarity won't hurt momentarily. The blade might not even turn if it's hooked up backwards. If it turns the wrong way just reverse the wires.

my current case fans screws are 3.25 inches apart and i was wondering if these are the same or is this fan too big for my case?

This is a 120mm fan. So it's 120mm side to side. The holes are about 105mm center to center. 105mm is about 4.13 inches. So this fan is too big. 3.25 inches is about 82.55mm, so you are looking for a 92mm fan with hole spacing of 82.5mm FYI, The 80mm fan has hole spacing of about 71.5mm

What type of bearing is used in this fan, and how does it impact the fan's performance and lifespan?

The fan uses 2 Ball bearings, which are known for their extended life and high performance.

What is included in the package for installation?

The package includes 4 screws for installation.

How noisy is this fan when operating at high speed?

The fan has a noise level of 35 dBA when operating.
