Hello, i am planning to upgrade to a BFG GeForce 8800 GTS 512MB PCI-Express Video Card, and i am wondering if my case temperatures and cpu temperatures will increase, even if it is a slight increase. Since im new to the forum i cant post any links but the pc i have is a hp media center m8125x, if u search it in Google you'll be able to find it. I upgraded the psu on it to an Enermax liberty 500watt. There is no room to put case fans, and there is only 1 exhaust fan in the pc. I know for sure that the card is able to fit inside the case as i have already measured it. Thanks in advance.
