There's no extra place to hook up a fan. I bought this computer and they made it not very upgradeable. The only things you can upgrade are the ram and the cards.
That's why I'm sort of worried about getting a XT. If it overheats I have nowhere to go.
Yeah i use a 9600SE i think i got a 300watt maybe 350 no more im pretty sure its a 300 tho its the standard wattage and it handles it well my card slower tho
if your case doesnt have and places to put fans u should think about a new case, doesnt have to be expensive but it would most likely solve the problem of your current card overheating
