What's good to put out a cpu fire?

[JAD]

hmmmm If that i the typical example i have some fears about that.
those domes look pretty wide at the top...certainly not the diameter of a
standoff/pylon/stansion

Yes, they are the diameter of a standoff, at the center nipple.

If you mean the type that has the PSU mounted on it's side, rather than
horizontal across the top of the case, that was a common socket 7 layout to
keep the case shorter, but also a bit wider. Pleeeeenty of room for the
kinds of heatsinks used on those things. I'd imagine they were also used
for socket 370 and you actually *can* get a standard slot-1 cart to 'just'
make it, but not the 'typical' slotket because they're taller. It would be
a real problem for the larger heatsinks of today.

Until about a week ago, I used just such a case for my kids' computer
(sold now). The CPU is mounted behind the PSU. There's only about a
1/2-inch clearance between the CPU fan and the PSU and at first I was
concerned about heat issues, but there seemed to be no alarming temp
rise with an Athlon XP 2400+, stock heatsink-fan and no case fan.

Interesting. I'd be nervous with no case fan but, if it worked...

I've just scouted through this thread, and I catch out of it:

1) The CO2 extinguisher thing wasn't mentioned. However. I think I
want to keep an eye out for a small CO2 extinguisher. Firstly, no
chemicals that can upset my head nor liver. Secondly, if I use it,
the CO2 in the air won't cause much difficulty -- maybe a little
breathlessness, in which case I open the door. Third, CO2 kills
fires. Finally, the CO2 is cold, to good effect upon something in the
computer that is hot. So CO2 looks better to me than anything else I
know of, and I need one here.

2) Motherboard grounding is a bummer. If you're rebuilding an old
computer then you want to keep tiny sketches in your notebook how it
came apart so you can reassemble it same way: the little paper washers
and etc. ...You *do* keep a notebook, don't you?

3) Ventilation. Before you do anything else, have a common-sense look
at how the ventilation works. I once bought a box and surprise, no
way in it for the air to get *in*. So I cut five large holes in the
side right over the CPU. It's worked fine for some years.

4) Boxes. Cases; cabinets: around here we call them *boxes*.

Roughly speaking (I'm not giving advice), that depends on how quickly
the CO2/whatever changes the temperature. I think that putting out
the fire is what matters.

No, it's not.

Oh brother (or sister).

...You *do* keep a notebook, don't you?

No, I have been using digital recorders for years. Yes, I take notes
with that.

Off-topic. For what it's worth. A digital recorder is quite cool IMO
for technical things. At least here (in the United States), the
price, function, quality, and recording time is eclipsing cassette
tape recorders. The improvement is crystal clear IMO if you consider
the convenience of being able to easily access your recordings. For
loud/realistic playback, the computer speaker connector plugs into
the earphone output.

Me too. But in this forum, I have referred to them as cases.
