Reducing speed / RPM of pedestal fan Answered

I have a 400 mm pedestal fan rated for 230V 50Hz AC, 120W with minimum 2200 RPM which uses motor coils winding for speed regulation. Its speed and noise is very much even at lowest setting. I want to reduce its speed even further.

I am thinking of three options - one - changing the OEM fitted 3.00 micro-farad 440V capacitor with 1.5 or 2.0 micro-farad 440V capacitor, second - using a capacitance based speed regulator (used with ceiling fans) and the third - using a resistance based speed regulator (least preferred option though).

Please tell which option will work fine without doing any harm to motor coil? Any other options are highly welcome.
