thermo nuclear cpu

[sentinel75]

In the labs I've seen cpus get upwards of 120-130C. 80C isn't even boiling yet.

Melting point of silicon: 1687?K
(1414?°C, 2577?°F)

*Sigh*  Please, go read the page on semicondutors, then the page on electronic band structures and take note of the equations with a temperature factor in them. Short explanation: small fluctuations in temperature cause large variations in the conductivity of semiconductor materials.

By the way, my iMac G5 CPU runs at an average temperature of 65°C (max allowable 85°C). And how, exactly, does Fanspike measure the CPU temperature? (The iMacs use a thermometer device on the CPU or heatsink)

FanSpeed is a small free utility designed to run under Windows 95/98/NT/2000 to control the speed of case and CPU fans depending on the temperature readout from the available motherboard thermistors.

Righto, thanks. I was wondering a) if the CPU was measured directly and b) possible error (there was a temp. utility for the Mac that attempted to provide a temperature calculated by the Mach kernel)

That joke went RIGHT over your head.

[sheepish] Yeah, it did when I wrote my post. I looked at it 2 days later, and just went *facepalm*. I've always struggled with the fact that in forums, you can't look at someone's face/hear their voice and figure out what they're really saying. That, and I've always been a bit pedantic...

Back on topic - for those who are worried about hot chips, try and stick around until they've made a chip out of CVD diamond. The increased thermal conductivity should help with heat issues, esp. regarding heatsink size and fan power.

Thats sounds awesome...

What, a CVD Diamond processor?

I reckon it would be REALLY cool if you made the entire motherboard out of some kind of transparent conductive material, possibly silicon printed directly on to glass. Is CVD diamond transparent? Put inside a high quality glass/brushed metal case with a window, you'd have a veritable artwork.

Because glass has a far higher heat tolerance then conventional plastic, the computer wouldn't contain so many toxic plasticish chemicals, and wouldn't smoke so easily. Plus, it would probably be almost invincible to damage to due static electricity.

(Obviously, it's probably impossible - but it does sound very cool. I heard they were experimenting with glass PCBs for PDAs and things... so it might be feasible...)

For the most part, copper is the conductive used for the traces in motherboards. it is the semiconductors, such as the CPU, that uses Silicon.

The problem with glass is that while it may be heat resistant, it is very shatter prone, especially in thinner layers.

Of course, unless you induced some kind of standing wave in the glass, to cancel any dangerous vibrations...

Admittedly this technology is probably too sophisticated to appear in consumer machine.

That wont stop us from drooling over it.  I like the new ideas Intel is using with its microprocessors and memory transfer architecture, using light.  Could be pretty darn cool!

Actually, we mean thermal shock. Chuck an expendable, non-Pyrex dish in a hot oven and you'll see what we mean.

Glass also becomes more fluid (less viscous) the higher the temperature...

And CVD diamond processors may be any colour from yellow to pink, green, black or brown, depending on what it's doped with.
