This is something that I really wouldn't want to decide on. Whilst the connectors sound very similar they could be wired differently. My feelings would be to not connect anything I was unsure of.

Why do you want to connect it to there anyway?

some boards have a header for the power supply OR so this is my understanding-some boards have 3 fan headers- my board has 2 one for cpu and one for a fan =like i said my fan attachs to a  4 pin molex? so my chassis or case fan header is free-so i was wondering if my simaliar 3 pin plug from the power supply could go the other fan header?

Your board should have three fan headers  a CPU fan, Sys fan and Pwr fan. They are to supply power out to fans  and nothing else.
