Time to vacuum your notebook (e.g. for Kubuntu Linux)

Noticed the same with my

Noticed the same with my Notebook, core temperature was at 98° with only one core running and low ambient temperature. So I used compressed air and the fans blew out an unimaginable amount of dust.
After that the temperature did go down about 10°C with the fans spinning much slower.

I never had any dust problem with the desktops, one is running as a server for 8 years 24/7 BOINC is running on it for 4 years and didn't clean it once yet.

Took me a while to convince others at my workplace to have desktop computers on the desktop. Under the desk just doesn't work well - you magnify the dust issue tenfold. Effectively they become floor level electrostatic dust precipitators. Not to mention kicking them, spillages and the like.

A friend of mine is an investigator for the regional fire authority and increasingly it has been found that upward facing powerboards are a likely culprit ( or alternatively more favoured by arsonists! ) for office fires. The three slot receptors for the 240V plugs collect a fair share of lint to the interior of the gadget, and more so on the floor. In offices that lint is likely to be paper based ie. combustible. Mounting them well above floor level with the receptor facet in some horizontal direction ( or even better directly looking down ) is the go.

Cheers, Mike.

( edit ) and a powerboard without overload cut-out is just silly.

Mike, what is a powerboard? I'm not joking or criticizing, but in genuine terminology deprivation.

Sorry, a multi-outlet adapter, 240V AC plug/cord one end and, various designs, up to about 8 ( 2 rows of 4 each ) 240V tri-way receptors to feed off. Optionally come with an over-current trip switch, or slow-blow fuse, and over-voltage short pathways ( perhaps resistive to swallow up a few Joules from that lightning bolt ) for surges. I like the ones with the pretty status LED's. :-)

Some larger types are really small UPS's with brief ( minutes of ) battery backup. These features have saved more than a few components of mine. I live half way up a mountain range where falling trees across lines etc are commoner than transformer maintenance crews. It can be quite dramatic when a particular phase line meets it's 120 degree cousin!

Cheers, Mike.

( edit ) I expect you know these by another name .... note the bowl shape of the receptors ( 'plugholes' ) which encourage the lint issue.

We here make a business in

We here make a business in cleaning computer boxes around the city. But it is quite simple to open a box and blow out the dust powder with my own breath and then just clear all the components with the squirrel-wool brush (just to keep out the static electicity) and then blow out again all the rest.
Once I opened the box and found there... that it was all filled with the huge dust clutch that I had to remove manually and only then blow the rest dust). Sorry, I didn't made a picture to show you.
BTW, we usually disassemble notebooks to clear the dust, because otherwise some dust clutches will never be blown out because of their size. They stick in radiator slots and I have to remove them with tweezers and the reassemble all things back. Moreover, that way you will have the opportunity to grease coolers (that is usually made in China) with something like "HighGear ER" or "SMT2" that makes this cooler eternaly silent :)

P.S. Heatpipes rules!

Nope, there was no 80486 included in the Hubble in 1990. The part had only been introduced the year before, and there is no way that a space qualified variant would have made it into the launch hardware on that timetable.

As the actual article from the Register points out, the processor referred to actually was flown up as part of a repair mission many years later, and is not itself part of the long unused backup path which is indeed being turned on now.

Yes, indeed, this is out there wrong a good bit.

But I moved from the Intel design area in Santa Clara in 1988, with the 80486 definitely still in design, to Albuquerque's Fab 9.1, which was the startup fab for 80486--rather a while after I got there. So I knew it could not possibly be true.

Oh, the other bit is that Hubble had slumbered in essentially completed form for quite a while before being launched. At one point is was quite close to reaching a then-planned 1986 launch, when the Challenger event intervened.

Wow, my dual core AMD never goes above 70C, and it crunches most of the time. I have begun noticing some dust on the bottom fan intake though.
