After months of blaming my i7 desktop computer’s tendency to overheat on it’s high performance and small size, I discover that… the CPU fan was on backwards. fail. It’s temps used to hover around 50°C, now they’re down to just below 40. Recently, when transcoding a DVD with HandBrake, the temps got up to 80°C, but now with the fan reversed, and all of that dust removed, it rises to a reasonable 65°C. Happy days!
