Does more memory require a more powerful fan?

That sounds thorough, but you're still exposing yourself to the gases. They sound risky. Trichloroethane is a known carcinogen. I wonder if these gases are any less reactive. Either way, I think it makes the most sense to use filter material in the vents. I haven't needed to clean out dust for years now. I just occasionaly vacuum the air filter material, from the outside. |

What he says is correct: "there's no problem vacuuming as long as one doesn't touch the components." But you shouldn't use a vacuum cleaner because there is always a risk that you may accidentally touch a component. Saying "I've done it many times with no problems" is like saying "I've driven without wearing a seatbelt many times with no problems." Right, but accidents *do* happen. |

That sounds thorough, but you're still exposing yourself to the gases. They sound risky. Trichloroethane is a known carcinogen. I wonder if these gases are any less reactive. Trichlorethane. When I was a teenager, I worked in a factory during the summer when school was out. It was a large window & door manufacturer, the largest in the Northeast US. There were 55gal drums of Tricholrethane that we used. We would use that stuff to clean all sorts of oily, greasy things. Oddly enough, people referred to it as "safety solvent". As you note, there was nothing safe about it. Either way, I think it makes the most sense to use filter material in the vents. I haven't needed to clean out dust for years now. I just occasionaly vacuum the air filter material, from the outside. |

But, to be clear, this is not always a direct effect. Sometimes, when the compound breaks down, there are reactions with other organic compounds which make what are the actual carcinogens.

I guess I should amend my advice: Never vacuum if there's a chance of a truck careening out from between two PCI cards and running a stop sign at a RAM socket.... at least not without your seatbelt on. |

I do remember the time I was over in 5F, in Brooklyn, and I was being careful, didn't even notice making a mistake, but I must have touched something a lot hotter than 110V, and the shock or the fear knocked me 10 feet back. Started my shoulder dislocating every few days, when it hadn't done that for 8 years. I think there was 2000 volts nearby. |

Now if that was my university, the students would still be using those buildings :-) And all the grads would have a "rosy glow". Paul |
