I have a small form factor Dell Optiplex GX260, 2.53 GHZ, 1 gig RAM. I recently installed a Nvidia Geforce FX 5200 card in the only available PCI slot. That slot happens to be really close to the power box. After 10 minutes or so of playing a very low requirement game, the fan turns on and the game play is slowed down a bit. Is the card being too close to the power box a bad thing? Will it increase the chance of overheating? Would it be possible to maybe transfer the motherboard from my small form factor case to a bigger case to give it better ventalation? My motherboard is an Intel P4 82845G.
