Att göra rent datorn med en dammsugare är skadligt för komponenterna. Myt eller sanning?

For many years, I've been using an electric leaf blower to blow out all the dust and debris from inside of computers that are brought to my shop for repairs. However, there were know-it-alls on the internet who insisted this was irresponsible and dangerous. Claims that the spinning fan creates voltage that can damage the motherboard, or that fans that spin too fast can break. Neither of these things are true. But one thing is certain - no one who ever made these claims had actually tried. They have no experience and are 'google experts. Otherwise, they'd know they were wrong.

This is a collection of videos I've made over many years showing me blowing out numerous computers with leaf blowers and none of them have ever been damaged. This way, I can prove, via videos, to those that lack actual experience, that no damage is being done.

The quality in these videos varies as I was shooting in SD 4:3 and and then 16:9 and then HD 16:9 and then 4K 16:9.

It is not recommended to use a vacuum cleaner or an air compressor. Air compressors can have too much PSI and damage the PC, condesnation builds up in the air tank (water filter is necessary) and air stream that comes out of nozzle is too narrow. The issue with a vacuum cleaner is it enourages you to make contact with the parts inside of the computer with the nozzle. Whether the nozzle is plastic or metal, static discharge can very easily occur and much dust will still be left in the PC despite what your eyes see. If you have a shop-vac that can blow air out, that would be a viable alternative. A hairdryer will get too hot and does not have enough air pressure. You want a wind-force of 120mph. You simply won't see a hairdryer that powerful.

If you do not have access to a leaf blower or a shop vac, I highly recommend you use the little cans of air duster, often sold where computers are sold. I do not use those little cans because I am a professional PC repair shop and it would cost me thousands of dollars every year and it is bad for the environment. If you are only blowing a couple of PCs per year, the canned air duster is just fine for you.

To those who remain skeptical, your fear is easily remedied with a little education. Specifically on electrical motor theory and diodes.
