I'm sad to announce that the "NO computer-case machine" has failed. I couldn't take any pictures, but as soon as I try again, and I will, I'll come back with photos of a computer all over my desk. I tell ya, it's good for cooling it down... 8)

the 'what' failed?

I was trying to stert up a computer that had no case, only the poser supply, disk, CD, monitor, keyboard and a mouse scaterred over the desk. The test failed, actually went to flames, as the cpu started giving away a small smoke signal. meaning don't do that... and I didn't :lol: I'll try again with a bigger cooling_fan

[Insured Disaster]

So let me get this straight. You are going to show us a picture of a computer in peices? Laying on a desk? And not even on fire? Why, I have taken apart several PCs and know freinds that have PCs in various stages of assembly all over their house. They must have 25 PCs laying around the place.

"I tell ya, it's good for cooling it down... Cool "

All I can say to that is that its not good for cooling it down if it burst into flames.

But please, show me the picture. It might look cool indeed.

ID, the "notice" in the first post above (since removed) was placed by me. He posted the poll and the first message but didn't have anything to support either.

Sorry, my fault, I forgot to put my name in there.

The point is not pieces of computer, there are all hooked up, and working, producing nothing but a positive Horizontal and Vertical Sync on the monitor, but I'm still working on it. After I'm sure the MOBO works I'll buy a case, and I'll have the third comp in my house, yase :twisted:

The mobo has been declared as inoperative, and snce then it was working fine for an hour, then after a reset decided to flame up a little. I think it was only some plastic dust (been using a sanding tool near the test area), that melted, but you can never be too carefulf with computers, especially not if it is an Intel!!!

[Pilotwannabe]

is this another secret ploy to see who is the real technically inclined? or do you actually want to know?

[ATR_flyer]

:lol: no I really want to know if anybody sucseeded in that. Don't worry...although :twisted: interesting thought...*dramatic music*

[ricktobin]

Starting a computer up without a case isn't anything brilliant.

As long as you have some level of common sense and understand the effects of shorting out components on the motherboard from ESD prior to applying power or shorting out every component on the board by not insulating it from whatever surface it's sitting on (the reason they have standoffs between the board and the case) once you apply power.

Hey, it's your money, spend it how you like. We've obviously seen by this fine example who NOT to send your computer to for repairs.

[Insured Disaster]

I wonder if you had a short somewhere in the system. Many power supplies are very powerful these days that though I wouldn't be absolutely sure, you might have had a short. A short can creat massive amounts of heat and melt plastic with as little ast 12 volts, supplied by a few AA batteries.

[Maxell]

Insured Disaster, all of the power supplies have the overload/short circuit protection. When you connect the main +12 and GND the power supply will limit the output current to 5 mA, and thus protect itself from overheating and the mobo from flaming up.

I did the almost same thing: I removed the case because of the cooling, it was supposed to be online 24/7. I laid the mobo with the gfx card sticking out, on a piece of sponge, the one you get in the box of the mobo. And it worked, and still does, after 3 months...the temperature has been reduced from 46*C to 38*C which is outstanding.




Lot's of greetings

Well obviously ATR did something you didnt' or vice versa, as yours has not burst into flames. I didn't know about the protection, though I was just saying that it only takes a half a dozen AA's to create anough heat to melt plastic.

[Maxell]

I have an old power supply converted as a lab adapter, giving +12, -12, +5, -5 volts, and all the other combinations with those. I gives about 7 amps on +12v, so I tried to cut metal wires with it, as the excessive heat from the spark is hor enough, and the electric arc-ing is also used for the process of putting together two metal surfaces with a stick of other metal that has a low critical melting temperature. Not soldering!!!

So I found uout about the protection in a rather hard way, didn't burn it :twisted:

BTW: I love the bike conversion, seems we have something in common, just don't make sharp turns with such a high gross weight 8)

[paulvil]

Maxell you are lucky there was no damage (esp to the CPU) because the main goal (other then dust) is so that the power supply fan can move more air out (weak suction) with case open there will be olny a cross-brease

[Maxell]

Inetresting reply, Paulvil,
but that is theory, in practice it is a lot diffrent. I'm the proof that the no case feature helped the CPU and the overall hating problems. Ofcourse the cooler on the power supply has been turned so it blows into the power supply, at the semiconductor (gretz, briged diodes) coolribs. Also there is no hot air inside the case, as there is no case att all, and thus no place for the hot air to get trapped in. Also about the mains short cicruit, I tried that on the lab adaptor, made from an old PC power supply. I only said it to make it clear about the overload protection.



You're on the right track
