Dusting Your Computer - Keeping it Cool @ BFR

My mother always told me to dust, but I never did, mostly because I was lazy, but also because I couldn't find any tangible benefit to dusting. I just didn't see how I'd benefit from my room or my things being less dusty. Well now I've gotten a bit older, and I finally found a reason to dust - a cooler running computer. I'm going to give some background on my own system and circumstances first, then run tests before and after dusting, as well as explain how and what I used to dust.
