Can't find fan header on motherboard

Yes, i'm back with that Pentium 3 (Celeron 700mhz) machine, now i found out it was psu problem, but the weird thing i see, that there is no fan header on motherboard, is there anything to do about it

  • Did you already look up your motherboard manual or Total Hardware 99?

    In the Pentium III days the fan header normally was a 3-pin header with index tab that was close to the CPU socket. You should identify it easily.

    Before that a unspectacular 2-pin header was quite common. So check unconnected headers.

    And before that, in the Pentium I era, you had to bring your own fan power via a connector you had to attach to a HDD power cable. This would be your last resort :)

    should try after looking through motherboard, and maybe also after buying new psu

  • Ok. But that PSU won't give you a connector you don't have already. ;)

    If you really can't find a fan connector on the motherboard itself (what's the model, btw?) you might need this:

    also through my tryings to find, no result, the only way i could think of is to turn on, but problem is, how do i turn on pc that i can't turn on
    edit: i told about the model

    @megamanyoutuber: What about the mainboard model.

    On a PIII system the switch is a header on the motherboard, too. ;) The 2 pin case switch connector goes there. I suggest you get a manual (I wanted to help and therefore asked for the model). Oh an please don't turn on a 700 MHz CPU without a working CPU fan, it could become damaged.
