Alright, its 2 a.m. now (I'm waiting for 3:30 am to see Jupiter eclipsing Io on the telescope

) and room temperature is 90ºF...
As Firewall said, all the fans in the world can't do anything if the room is hot.
My card is a nvidia geforce GTS250, so yeah, it was born to heat up.
I happen to have A.C. in this room, but buying and installing it is just a fraction of what having it running costs
