Re: strange behaviour of my desktop "yes, fans seems to work fine..." "I'll add the obvious: It's not enough that they spin, there has to be airflow through the heatsink that the fans blow across, and throughout the cabinet. Also, heatsinks need to make good physical contact with what they're attached too." _____________ Worded twice as good as I could have.. "perfect!".. Adding to it: There's a LOT more to the "bad-fans syndrome".. If you sweep the rooms while the computer is running, some of that airborne-dust will be sucked into the tower.. Dust in brass fan-bushings causes heat build-up, which bakes the bearing surface, and bakes the dust into abrasive carbon, which is essentially "ultra-fine sandpaper", which wrecks bearings and bushings, which is why corporations spend $millions on clean-rooms for their computers... If the tower is set near a hot air vent, the fans will pull-in heat, and heat what they're supposed to be cooling... You know the CPU fan is failing, and/or plugged with dust, when the OS crashes every hour or so... You really know the CPU's heatsink is seriously dust plugged, when you smell hot dust and overheated electronic components, emitting from the tower... If the tower is set near a cold air vent, the fans will pull-in airborne dust whenever the computer is running... Open your towers, and check to see that the fans are silent, and the CPU's heatsink is absolutely dustfree.. If the fan is plugged-up with dust, your computer will eventually bake its hd into trash... Every old tower that one acquires, the first things to do are: Don't bring it straight into the home.. Bleach wash the case, then open it outside, upwind of it for-sure.. Those things are dust and bug collectors.. Bedbugs is nearly a global epidemic now.. Mites is already a global epidemic... Use air pressure, plus soft brush, to clean the tower inside.. Try to be upwind of the dust, that stuff is seriously bio-toxic.. Bleach what you can... Don't spray it with bug sprays.. Those sprays melt plastic, and damage eyes... Maybe someone could invent, build, and sell "tower dust cover boxes" to be set on top of towers, so all the air the tower gets is already filtered dustfree... Add a plastic duct-pipe for the tower's exhaust.. Not good to restrict cooling fan exhaust... Maybe RedHat could patent this filter-box, and make some good money on it.. a gift for allowing us to use this wonderful Fedora gem for free... Maybe there should be a link to send RedHat our ideas for them to make money with, in return for the great love they are sharing with humanity and you and me, in the form of "Fedora"... -- http://www.fastmail.fm - Does exactly what it says on the tin -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
