are you sure? done a bit of research now. i've read that fan xpert and fan xpert+ doesn't have the ability to control 3 pin fans, only fan xpert II does, which is included in asus ai suite III. aisIII is only available for version rog vi mobo's. mine's a version iv. there is a thread where some people got aisIII working on older boards, but DC control over fans is hardware based so even IF i could get aisIII to work, it's HIGHLY probable that fan control would still not work.
