Yeah, probably not so severe in a compact home system. There can be a lot of volume in a large garage system -- Andy Hewitt <http://web.me.com/andrewhewitt1/>

True, and you don't have to go outside to do it and whilst I'm sure it works, I'm not sure it would be quite as good at getting into all the little places as a good blast of air might (like a desktop PSU). Plus on an open desktop machine you have the issues with static and a vacuum cleaner (unless you are using one designed for the purpose with carbon bristles on the brush etc) and the chance of knocking something. Ok on a laptop that way though. And my compressor is lighter and smaller than most vacuum cleaners, never needs emptying and can also pump my car tyres up (which I personally find more useful than cleaning the lounge carpet). ;-) Cheers, T i m

Not something you'd want discharging across the motherboard! I did use the vacuum cleaner myself this time, but only lightly waved over the cooling duct to remove the loose dust I'd dislodged with the brush. -- Andy Hewitt <http://web.me.com/andrewhewitt1/>

I think they would be ok with laptops but outside of removing external stuff and the bulk of cruft in a desktop I'll stick with my little 'presser. ;-) Cheers, T i m

My wife went to New York. Whilst there she rang me up and said she wanted to buy a laptop, so I told her to go to the Apple Store and get a MacBook. Erm! She didn't! She went to look alright, but she thought they were too expensive, because she didn't want a white one, only the black one, which of course WAS the most expensive MacBook at the time. So she went to another store and bought an HP TX1210US. After about a year it started randomly dropping off the wireless network, and could only be persuaded to rejoin by rebooting the machine. It also blew LOTS of VERY hot air from the exhaust vents when running. A few months further on, it would suddenly lock up, again requiring a forced restart to get going again. The frequency of these lock ups and wireless drop-outs would increase all the way up to the two year birthday, when almost exactly 2 years from the date of purchase, it locked up, and completely refused to boot at all after that. It was then that I discover this particular machine used the same motherboard design and graphics chipset as several models of HP laptop that were subject to a class action lawsuit for the very reasons my wife had problems. She has since then be 'forced' to use my old PowerBook G4, which of course is still working perfectly. |
