If your chakras are not strong enaugh, no.
Spinning them may keep them safe, and it may also help to open them, but it doesn't replace the power of mantras, You have to give them energy by chanting mantras, spinning them is not enaugh. Im not sure if it's insuficient but it's not enaugh to strengthen your chakras.
If you have to be quiet, vibrate them quietly, or in your mind.
If your chakras are open, and strong enaugh you can just meditate and spin them without mantras.
