My Athlon64 is at 53C when idle (room temp quite warm). I'm thinking of getting an exhaust case fan to lower temperature. Will an exhaust fan be useless if I didn't have an intake fan? I don't have any holes on the front or sides of my case, so I can't really use an intake fan.
If I were to get an exhaust case fan, how many degrees should I expect the temperature to go down by? I'm thinking of getting a 120mm 1200RPM fan.

Whoops, I meant 1000RPM.

I'm already using an Arctic Cooling Freezer Pro 64 heatsink/fan and OCZ Ultra 5+ thermal compound.

Are you sure there isnt a way to cut a hole in the side and blow a fan straight on the processor.
Otherwise id look at a better cpu cooler in the aftermarket world.

If you want to cool your system, you need to have some sort of intake wether that be a fan or just holes, you need something, two exhaust fans will, at best lower your air pressure, solving nothing, you need air flow into and out of your case, if your exhaust fan is in the back I highly recommend an intake fan at the front of your case. The cooler air comes in and acquires the heat from your system, and the now heated air is taken out by the exhaust fan(s) and the air taken out is replaced by the intake fan with cooler air, if no air is replaced the cooling process pretty much stops. If it becomes a serious problem taking off a side panel may be necessary, in which case fan placement isn't as important and no intake fans causes smaller problems, because the intake air is coming in from the now open area, if have had to take a full box fan to cool my system, I do not recommend this though the high air pressure it makes may harm you components. Also, while size is sometimes better, a 120mm fan has a larger dead stop with no air flow, because of the larger motor spinning the blades, also I see cfm (cubic feet/ minute) as being more important so you can get better air flow.

You already have a good processor cooler. You just need good case ventilation to bring down the temp inside the case. Your power supply is also an exhaust fan. Your new 120mm fan will improve air flow. Try to cover openings for the PCI slots and other openings at or above the level of the exhaust fan. This would ensure that cool air is drawn from the lower part of the case. Make sure that there are enough air openings at the lower part of the case. Otherwise, the power supply and the exhaust fan will just try to outdo each other in sucking air. Instead of creating air flow, a vacuum might just be created. Case temperature will just rise.

it would improve the airflow cuz if u just have an exhaust fan, the air is just slowly flowing into the computer and staying in there for a while with nothing pushing it. if u have both an exhaust and an intake fan, the airflow circulates
