I've got a noisy computer....


Recommended Posts

....probably time to give it a clean. It whiffs a bit too.

Been out and bought an air spray (??) cleaner.

Going to open it up - first time in three years - what should I be careful of??

What should I puff at?

everywhere really, the fans of the processor are harbours for lots of dust... just give it a good squirt and make sure you have the hose of the vacuum ready to suck up the lose particles. Just make sure you dont' touch anything with the vacuum.

Do be careful to fit your Byte filter on your vac. first, because if you get a dust bag full of bytes 1) they take an awful lot of time to pick out from the rest of the bacterimoles and gobblethrites in there and 2) after you have washed them, prior to replaceing them (as you should), you will find that hanging them out to dry on the line is fraught with difficulty (not to mention the bird s***).

I find a soft bristled paintbrush is also useful for cleaning fans.

The company that I was with for over thirty years found that something stronger than a paint brush was needed. Although it was usually something much heavier and smellier than computer dust that hit the fans there! :whistling:

If we don't hear from you again we'll know you buggered things up.

Well I didn't! :lol:

It wasn't actually that bad. I was ashamed of the dirt behind the case though!! :blushing:

Everything is sparkling! ( that dull spot on the screen was a dirty smudge)

New resolution to clean up every 6 months or so.............. :rolleyes:

andsome, everyone.

Dust accumulates in the most fastidious of households and a computer, by the very fact that it draws air into it, collects dust on all it moving parts (fans) and on all areas where there is an airstream.

I've just started using Antec cases which have a plastic grill to filter all air that goes into the machine. It's quite shocking how much stuff it has coolected in only a couple of months of use. We do have a dog but I don't think he is responsible for all of it by any means. This grill does quite a good job of keeping the insides clean.

I would recommend to everyone to check their machines for dust on a regular basis (6 monthly?) and do the necessaries when necessary. The muck can't be doing your working much good.

Glad it all went well.  How old was it?  Mine is eighteen months now and I have been wondering about dust build up.

It IS actually 3 years old.

I given a thought to cleaning it a few times.............. :rolleyes:

It has been getting a bit noisy - but only on start up, so I ignored it. The smell worried me though. Mind you, hubby said I imagined it.

I feel all holy and pious now!! :D

I have wondered about filters. If they were regularly self cleaning and electrostatically charged they could be worthwhile. My worry with them has been that the more effective they are at filtering, the less the amount of air they allow through. In order to filter out the semi microscopic dust, which circulates in all our houses, the filters really need to be fine, and unfortunately the finer the filter, the more resistive to air flow it is, and the more so does the filter become as it does its job.

In order to solve a particular problem, some twenty years ago, I set two of my department's scientists the task of finding optimum air flow speed for cooling a particular product. It turned out that 5mph was about optimum. Any slower and the residence time was too short for optimum heat saturation and any faster energy was wasted because insufficient residence time was allowed. (There were other factors but they need not concern us here.) Hence I have always been concerned with air throughput.

It is the microscopic dust which is electrostatically attracted to the variousparts of the cooling system which is the problem. The coarser the dust the less it is attracted (and for that matter the less it is air born.) I think that there is scope here for a Dyson approach (i.e. unconventional) Maybe external electistatically charged plates between which the air is directed prior to entry into the machines entrails.
