Using your own breath isn't going to do much and certainly has it's own issues, spit/moisture.... -- 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.

Most people are not going to be lugging an air compressor around; and why should they when a simple lips to the out-hole and a few puffs will dislodge the dust? >Using your own breath isn't going to do much and certainly has it's own >issues, spit/moisture.... I have done this countless times and blown out a good deal of dust, so much so that formerly hot running computers now run cool. You're operating from theory; I'm operating from real life experience. Yeah, it's not elegant, but a lot of repairs are not elegant. I learned this from a car body shop when I noticed that people often fixed bumpers by removing them and then jumping on them. Of course, never show the inelegant fix to the customer...

All I can say is that I'm operating from personal experience. I used a can of compressed air and a couple puffs was enough to bend a fan blade so that it woudn't even turn. >I wouldn't use any "furniture polish" as you don't know what chemicals are used > which may cause corrosion of electronics. Again, I'm saying to just LIGHTLY spritz the feather duster, NOT saturate it. The idea is to give the dust something to hold onto. Some feather dusters have enough oil on them naturally that this isn't necessary, but some don't have enough natural oil to do so. I'm talking from personal experience. The computer I'm using at this moment I dusted in this manner about 2 years ago and everything is working fine. In fact, SpeedFan shows that all 4 temperature sensors are operating cool -- 34, 48, 34, 33 degrees Celsius. The last time I looked inside, I didn't see anything odd about any components, either.

It is the wrong solution for electronics. For a blade of a fan to be impacted by air pressure from cannister of compressed air the blades would have to be of pie tin grade aluminum. There just isn't that mch force. -- Dave http://www.claymania.com/removal-trojan-adware.html Multi-AV - http://www.pctipp.ch/downloads/dl/35905.asp |
