    fans

    Hello,

    I need some extra information and hope some of you can get it to me.
    On the motherboard (GA-8I915P Duo Pro support.) there are 4 fan-connections
    - pwr fan = ?
    - cpu fan = cpu processor big cooling fan above the intel p4-- if not it wouldn't last for long
    - sys fan = ?
    - nb fan = north brige fan ?

    Why or for what purpose are all those fans there. To cool that's for certain and I figured out two of them
    "cpu" = central processor fan and "nb" = north bridge
    But the other two
    sys fan (system ? describe system)
    pwr fan (power ? describe power)
    i cannot see clearly.

    Cpu an NB is can visualise and find the corresponding part on the board. The other I cannot.

    Please help me out.

    I hope I am understing correctly, you need to know what these other 2 fans are for? The sys fan should be bringing air from the outside of the case, is it? These are not always installed, but help in keeping the system cool. The power fan? sorry can't help much with that one.

    hi,

    you helped me in this case. I sustected that they would be supplementary fans to cool the case. Still anyone who can give extra info is welcome.

    Thank you

    Just google the MB part number. I'm sure you'll find a manual you can download or look at online.

    Re: fans

    From my experience, a system fan would be connected to the case to blow in cool air from the outside. The last time I upgraded my PC, I reused an old case. Because of the newer and hotter components I was building, I decided to add a case fan to blow directly onto the video card. This connected to the system fan plug on my motherboard.

    Power supply fans are typically driven by the power supply rather than by the system (motherboard). But I can imagine having additional fans for the power supply - especially if it's a new, fanless power supply.

    If all else fails, Joe's suggestion of checking the motherboard manual will probably answer all questions.

    Hope this helps!

    Click here. This takes you to the dowload page that allows you to obtain a pdf manual for your board. It is available in several different languages. I hope this helps.

    As a side note, it is common for a case to have a fan (near the front) for sucking air into the case and an additional fan at the top or rear for blowing the air from the case. This is what keeps a good circulation of air flowing through your system. Many different cases, many different configurations. Maybe the manual will shed some light.

    Re: fans

    The pwr fan header should be for adding an additional fan for cooling the power supply unit, while the sys fan header should be the same as a chassis fan header (for a front-mounted "sucking air in" fan or a for a rear-mounted "blowing air out" fan). Both the pwr fan and the sys fan would be monitored by the bios. Depending on your motherboard, the bios may be capable of shutting down, or slowing, the CPU if either fan fails, similar to the monitoring that the bios does with the CPU fan. Or, the bios may just show the fan revolutions per minute. Of course, you can always forego the monitoring, and just hard-wire both front and rear fans into a power supply lead.

    Ricky,

    thank you for the assistance and the link provided with your answer. Indeed the manual gives partly an answer. Now I can make up my mind in buying such a board.

    Hello,

    your answer is very complete and more clearly than the manual provided by gigabyte itself. I know with growing proccesor speed there is more need of cooling your system down an thus more or better fans are needed. The problem is that often they use abbreviations and for technical iliterates it is not that easy or clearly. Before buying a board I want to understand some essential parts more clearly. Y
    Your assistance is much appreciated.

    For the time being I have the feeling I got the grasp over this subject and so I want to close it. Any other postings are welcome but, lets call it a wrap for now.
    Thanks to the members of this superb group.
