A 1. With part number maybe is enough. Go to "compatible" replacement, official may be sold to installed by yourself.

A 2. Looks like your fan is dirty or air conducts has dust. Since you need to open to replace battery, can clean with compressed air all cooling system and fan.

Identify the models battery from the Serial Number, which is on the bottom of the notebook in small type near the hinge.

Or from within the operating system find the Model Identifier.

To clean the debris causing the fan to constantly run may require more than just compressed air to clean as airborne debris usually included pollution that makes it stick.
I use ear cleaning cotton buds to clear stubborn grime.
Be sure to earth out any static electricity in your body before touching any internal electronics
