    motherboard fan headers

    how many fan heades do most motherboards have... the motherboard in my dell (piece of junk) comp only has one for the cpu fan and thats it.... im planning on getting a abit bd7II, anyone know how many fan headers are on that one, also just in general too? im trying to decide whether to get fans for the motherboard headers or for power supply plugs.

    they normally have 3 I believe...if you had three it would be for 1 CPU fan, 1 SYS fan(powersupply monitoring), and 1 Chasis fan header...all mobos are different, though, but that is what they are normally

    The BD7-II should have four. All the AMD ABit board I've used from this era have four (KG7, KR7A, KX7-333).

    As for fans, I prefer to power them from the motherboard because it makes wiring easier. Just remember you can only pull a maximum of .5 amps off of a motherboard fan header. It says so in the ABit manuals.

    And yes, you can use the PSU fan header for a chassis fan. You can use any of them for anything you want, provided you turn off the "CPU fan fail detect" feature in BIOS.
