Comment 163 for bug 22336

When I filed my initial report (the Acer Aspire 3620 laptop), I hadn't actually tried cleaning the fan/heatsink. The laptop had exhibited symptoms very early one, within a month or two of initial purpose. I don't usually have dust problems with the many other computer systems in the household. So I discounted the possibility of that being the cause. Just to be perfectly certain it wasn't the case, I have since cleaned the fan with a few blasts from a can of compressed air in the intake (bottom) and outgo (right side). I ejected a fair amount of dust and the machine now runs about 20 degrees cooler. With cpuburn running, I'm hovering around 65 degrees Celcius with occasional very brief spikes to 75 degrees. This is _without_ proping the laptop up on a book. Previously, with the laptop propped up on a book to improve circulation I was idling around 80 degrees and could easily hit 95 during moderately intense use.

So, disregard my report. And anyone else experiencing these symptoms on an Acer Aspire 3620, it's possible that some batches are shipping unusually dirty. (Naturally, you abuse your poor fan by blowing compressed air on it at your own risk.)
