You'll easily get a case fan for $AU15. Generally, you pay for silence. The more it costs, the quieter the fan. They are very easy to install if you already have a hole for one there. If you want to place it strategically over the CPU but don't have a hole there, it's a little more complicated to case-mod your box. Personally, I wouldn't do it unless the case has a removable side panel.

You'll pay a little more for a heatsink/fan combo, but this has the advantage of removing heat directly from the processor. The hardest part is removing the old heatsink.

One more thing you should check is whether or not each fan in your case is working adequately. If you're getting funny noises from your fans, the bearings have probably gone and need replacing. Hold your hand beside it to feel the air. If it doesn't cool your hand, you might want to get a more powerful fan.
