It could be that I've primarily worked on either "ancient" LTs that were built heavy-duty to start with, or "ruggedized" ToughBooks and such. Even the standard duty LTs I've worked on held up fine with the old "airgun", including fans. Disclaimer: Just because I said and do this, that doesn't mean that damage won't occur from doing it my way....inappropriately.. You don't place the nozzle directly on top of paper labels and blast them for minutes... I've been using "line air" off a 70 PSI or so air-compressor for years for cleaning all sorts of electrical, electronic, mechanical or "mixed' devices for going-on 40 years now. I'll admit to using a water trap tho. I did finally get a nozzle designed for "anti-static" use, it's nothing but a metal tube filled with copper/bronze mesh with a statground lead attached. I could have made one 7 times over on cost/time wise, damned thing cost $45 in '94 and took two weeks to ship it... The airgun cleaning is done on a grounded metal bench with an exhaust hood with a healthy suction. Computers; be they laptops or desktops.. are just another item, nothing special about them . I squirt the "bejejus" out of them when they come across the bench, going into every nook and cranny, especially the fans. I intentionally windmill the blades, both directions. This often helps break up the gummy lube by forcing the shaft past the gunk rings. If there's still a gunky film on the blades, I pull the fan and manually clean it (Windex works fine here). Same with optical and floppy drives, if the air didn't clean them out, open them up and manually clean them. If you've ever dealt with laptops (radios, whatever) used by fire departments, police, military, or utility crews, you'll have a good guess as to what finds it's way inside stuff.. I used to think the accumulated dog slobber/dander on the keyboard on K9 car MDTs was about the worst, but a cell hands-free kit installed by an outside vendor was the worst. The idiots put the "guts box" just under the console's cupholder. Driver was a very heavy user of RedMan chaw. You can guess the rest. (I'm still trying to figure out the mobile printer with a half-pound of birdseed-like millet, not sunflower seeds-inside, driver wasn't a pirate, not even the Seattle Seafair kind, and no birdshit found in vehicle.) As far as damages resulting for using the airgun? Yes, I have lost fans, 3 in 40+ years and probably 1000+ devices with fans. Was it *just* the airgun cleaning that killed them? Probably not. IMHO, if the fan *was* damaged by this, it was too fragile and needed replacement anyway! ESD /"static"? I know that ESD exists, and I've seen the actual damage done using a qual lab microscope to see the craters. I've yet to see a problem caused by ESD caused by water-filtered (and "grounded") air.

Like most of your BS, you didn't take away what you should have. The discussion is about PEOPLE doing stupid things - like blowing using the mouth, with all the MOIST AIR as well as sometimes spittle. -- You can't trust your best friends, your five senses, only the little voice inside you that most civilians don't even hear -- Listen to that.
