After ten years without a hitch there shouldn't be a problem. Depends
what you are standing on :) I did most of a degree in physics. For
that I had to study surface effects on electric fields as part of it.
Then there's the fact that static charge moves around different
materials in different ways.
I'm just saying I've seen it happen, and I've seen things like spraying
a conformal coating onto a PCB cause enough of a charge to put the micro
into programming mode. I've been servicing pc's for 8 years so I've come
across a fair bit of dust and crap lol.
I use a shaving cream brush (old style wooden handle, and some kind of
animal hair) to clean out my PC's these days, You can actually get the
layer of sticky dust off the heatsinks then, plain air doesn't actually
remove that. That layer causes a buttload of thermal resistance as air
seems to build up in a boundary layer over it rather than actually
passing over the heatsink itself. On 1RU style cases with fin style
heatsinks the best thing I've seen is a peice of paper folded up and
pushed between and along the fins.
