OK..I checked out the PCI slot fan..now I know how it woiks. BUT..does it do any good if it's blowing vertically?? Shouldn't a fan that is cooling the interior of the pc be blowing out some of the ventilation holes? Bear with me on this..I just don't want to put a 200 watt power supply in..and have it fry the MB/Processor or HD. OR does this fan work by sucking the air down and out the slot cover. I noticed on the pictures I looked at...it (the slot cover) has grills/fins, is that where the hot air goes..out the grills/fins (on the slot cover)? Thank you.....
