Ever wonder exactly what kind of temperature difference you're seeing if your PC's not dust-free? The guys at BFR did, & set out to measure the difference. Needless to say, I luv my air compressor long time.

"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."
