ok, first of all, I dont KNOW that i need extra cooling, but it DOES blow pretty warm air out of it and it is fully inclosed in an oak desk other than the rear being open. but i have the extra dough, and 2 empty pci slots, so i thought this would be the easy solution (i.e. slot cooler). dell (i hate em i hate em i hate em) has not left any extra room on the back for an extra fan. no place to screw one in even if i tried. what they have (so i have to keep going back to them non american speaking fools) is a nmb fan 92mm X 32mm with a plastic scoop that sucks air from the cpu heatsink and blows it out the rear of this thing. so what i need to know is do i want a slot cooler that sucks more air out of this tower (and if so, what brand is best), or one of those slot coolers that has the two fans that actually blow air around inside the tower and directly on the cards. and if i find a REALLY good cooling expert, is this stock dell nmb fan the best i can do? seems hard to find a 92mm fan thats 32mm deep (again, dell has made it so unless i modify the plastic scoop somehow, thats what i have to stick with). most are either 23mm or 38mm deep. ive replaced the ide cables with the antec cobras to allow extra breathing and unfortunately, mother board monitor doesnt work for my motherboard (have talked to mbm direct), so i havent a clue as to what the temps really are. now, as a newbie geek, i hope some of this made sense and helps you guys HELP ME!!!!!
