Here's the ULTIMATE cooling solution, plus you'll make some money, TOO!!
1. Remove the sides of your case (or the cover if it's that style case).
2. Unplug and repackage your speakers.
3. Return or sell speakers (hopefully for more than $10; see next step).
4. Spend $10 on a pair of headphones so that you aren't driven nuts by the noise of your ultra-super-cold computer.
Am I a genius or what?
