Hey i just bought a new case for my computer. Everthing fit into the new case but there is only one fan and that is on the cpu the case came with a fan to go on the back but it is inside a square plastic type box that turns and points onto the cpu fan and it was hitting so i took it off and i only have a two hundred fifty watt power supply with four four pin connectors is it safe to run my comp with only one fan until i get money to buy new stuff the motherboard temp is at thirty seven and my cpu is about the same my case temp says eighty one farenheit thanks
