Will this need a separate fan connector on my model?

The fan usually connects to a small power lead. Check the product pack for the connector type and ensure your receiver or auxiliary supply can accept the connection or use a simple adaptor if needed.

Can the heat sink be painted or modified?

Altering the surface can change heat transfer and fit. If you plan to recoat or machine the piece, take care not to block the fan inlet or change mating surfaces that secure the sink to the motor.

How do I check that it is fitted correctly?

After mounting, verify the fan spins freely and no wiring is trapped. Run a short test and monitor motor temperature and fitment after the first few minutes of use.
