Not sure what size fans I need

[Sacotool]

I have an Antec midtower case (can't remember the model #) w/300 watt power supply. Right now the only fan I have is an Alpha PAL6035 on an Athlon 850mhz cpu. I'd like to get an exhaust fan for the rear of the case in the fan space underneath the powersupply. I'm not sure what size fan I need, and do I need to get a mounting device, or do they usually come with one? I'm pretty sure I need either an 80mm or 120mm fan, anyone know? The computer is used in an un-airconditioned room and it get's fairly hot in here. Thanks!

BTW, the cpu temp is usually at around 36c, when I run a game for a while the temp goes up to about 44c. I've been having occasional lockups recently, that's why I decided to get a fan.

If it's an antec, chances are it's an 80mm fan hole. However, it's impossible to say without the model number.

You probably need some common fan screws to mount the fans. Although, some ANTEC's (ie. the SX series) come with fan cages, in which case you'd just snap the fan in.

thanks for the info, I'll try out an 80mm fan. Thanks again
