Although the manual says that you should put your videocard in the first PCI slot....can it do any harm to put it in the 2nd PCI slot? and by doing so: does it have a positive effect on the cooling of the Northbridge?

Because the hot nature of the 4870x2 I seek ways to make my system as cool as possible.

Another one...there is a NB fan connection on the mobo...but how can I mount an extra NB-fan on the mobo (UD5)?
