    Tubagon nko ni sa walay pag duhaduha bro.

    You cannot compare this 2 power source kay lahi lahi ni. Ang 7.5V DC pwede rah nimo magamit sa fan nga 12V DC ang supply pero hinay ni cya kay under voltage man. Pero kung 9V AC imo itaod sa imo fan bisan unsa nga fan sa imo PC dili jud na motoyok, masunog rana imo fan. Tungod ni sa direction sa current, ang AC usab usab ang flow sa current ani from positive to negative that's why naa ni frequency so dili ni pwede gamiton sa fan sa PC gawas sa kung electric fan imo gamitan. hehehe!.. Ang DC usa ra ang direction ani ug kani ang current nga gamiton sa Fan sa PC kay design man ang fan sa DC.

    I hope this will help you.
