I have the nzxt source with 2 rosewill led fans ontop. i have one connected to a port that says pwr fan and the cpu fan is connected to cpu fan1 but there is another set of pins that say cpu fan 2. is it okay if i plug the case fan into that one or is that a bad idea? its not that big of a deal if i dont or not , it will just look alot cleaner in my case.
