No you can't , molex = FULL SPEED.

ok thank you for letting me know

No you can't , molex = FULL SPEED.

Do you know if full speed is in any way shape or form bad for the fan or pc itself, my fan I think is 2200rpm full

Not really bad at all , will just be a little loud. They're well built fans.

If your motherboard has a 3pin you can use that with the 4pin fan. If your motherboard is so old it has no fan headers at all other than the cpu_fan, you'll need outside help in the form of a fan controller. These are usually 5.25" so fit directly where the optical drives are.

Noise is directly proportional to speed, so if just leaving the fan at full speed, it'd be just as easy to replace the fan with one that only spins 1000-1200rpm, gets similar airflow but a lot quieter. Noctua and beQuiet would be good replacements.
