Thread: Intel stock HS/Fan 4-pin specs?

  1. #1

    Intel stock HS/Fan 4-pin specs?

    ok this may be a n00b question but:

    I'm about to acquire a 3rd party for a s775 CPU, but i'm not sure if i could just use the MB's 4-pin fan connector with any standard 3-pin fan?

    well i'm not 100% sure but i believe the 4th pin on the connector is for sensors. So as long as you match the ground and live wire up to the right pin it should work as usual. only Problem is gettin it to actually connect physically.

    Hmm...MB with a 4pin fan connection? Every board I have seen has only 3pin pinouts for extra fans.

    So are you saying that the fan has a 4pin like a HD or ROM drive has and you want to power it from the MB? You can, but you need a 4pin-to 3pin lead. Now if the fan has LED's then more than likely it is powered off the other power line so using a 4-3 pin adaptor you will loose the LEDs.

    It's not the extra fan connectors but the CPU HS/Fan connector (small 4-pin, not like regular molex 4-pin ones). MB is Asus P5WD2 Premium (Intel S775). Stock Intel Fan came with this 4-pin connector.

    I just looked up that board, and it has standard fan connectors the 4pin you are talking about are the pins in a square shape?
    like this
    ¤¤
    ¤¤
    or molex style ¤¤¤¤?

    Square is an extra power lead needed from the PSU
    the HSF plugs in just above the memory channels on a standard 3 pin ¤¤¤


    EDIT I see what you are talking about, beside the motherboard power plug in is a molex plug, yeah you gotta plug it in there too

    No, it's not the auxiliary molex plug that comes with the MB, it's small just like a regular 3-pin fan header, only longer like this: [****]

    Just DL the manual for the board and it does have a 4 pin CPU_Fan connection...weird.

    From the looks of it there is a tab that offsets the plug from the fan onto 3 of the pins. This should be fine for a typical 3 pin fan. I do no know what the 4th pin does at this time.

    ***edited

    It appears that it is a way to monitor the power of the fan for control. Like to reduce the speed...the manual says
    "Only the CPU_FAN and CHA_FAN1 connectors support the Asus Q-Fan 2 feature".

    Link to manual
