Found this in another forum.. Thought it might be useful..
1. Clean up all the clutter in your case - Fat IDE cables should be replaced with rounded IDE cables, or tucked away, as they take up lots of space and thus obstruct airflow. If possible, the main ATX power connection should be tucked away as much as possible and only appearing when it must (when it connects to the motherboard)
2. Give air a direct path toward the processor and other heat producing elements of the computer (ie hard drive, video card, northbridge)
3. Keep the heatsink dust-free. The dust buildup on a heatsink can grow quite quickly, so make sure you clean up all the crap that gets stuck on your heatsink every month or so.
4. Use larger fans which spin at a lower RPM to provide the same air flow.
5. Cut out restricting fan grills! Not only do these impede airflow, but they also create extra noise!
These ones I've thought of for the last few months or so when my computer has overheated quite drastically (cough 70degrees C under load cough)
1. Open up all the front bezels that you can. Although this will let in a lot of dust, it will also let in lots of cool air.
2. If possible, stick a 12cm fan at the front of your case (three 5 1/4'' bays are required for this). The CoolerMaster 4in3 will be great for this operation. It basically converts the 3 5 1/4'' bays into 4 3 1/2'', while putting a 12cm fan in front of it! [But what I would do is just buy a 12cm fan and use string to secure it to the drive bays. I use string because it reduces lots of vibration as well.]
