Everything Is Cooler With A Peltier

Save your money! I have a Ppro 150 o/c'd to 180 that has been running 24/7 for three years with a cheap fan. Absolutly no problems yet. Even if your K7 dies in 1 year, you can take your $219 and buy a K8 1500. At my old job, we sold thousands and thousands of computer systems. The only processors that ever "died" were the early Cyrix chips that appeared to have the internal cache burn up. I recall only 10 or so of those coming back... ever.
Ahh, but what would you have said 10 years ago? I had a 286 (well maybe less than 10 years..) and thought "cool, it runs what I want".. 386s came out and I thought, "neat toy, but anything I want to do can be done on my 286". 486s came out not too much later and I was beginning to feel the hurt of not being able to run the latest things, games became more complex, everyday applications got sloppier with alorithms because they could afford to.. Finally got a Pentium 60 when they FIRST came out (i.e. people said oh my god, you have a *Pentium*, that things kicks!) This thing beat the crap out of my 286 :) It could do everything I dreamt of! Nothing would need more! Three years later, It wasn't enough to do hardly anything that was coming out new, got a P200, which was fantastic and again I was the envy of my friends... Finally, a little over a year ago, I upgraded my P200 to an AMD k6/2 400, because the 200 was a bit sluggish, but probably wouldn't have bothered except someone was on a slooow system and wanted my P200.. Then it was fast and did great things, already it is what software makers tend to expect of home users.. I'm fine now, but I don't think it is ever safe to say "I plan to run it for over 10 years, I won't need any more processing power than that! "
XML is like violence. If it doesn't solve the problem, use more.
I think this chap has made some good contributions to making computers more appealing to children, e.g. a PC built into a toy racing car and the Coke bottle PC, and recycling old parts to make some funky designs.
Pepsi compatable? Pfft, what about Jolt compatable? Us hard-core caffeinds like cold drinks too, ya know!
Anyone think they'll upgrade to 20 oz bottles?

The site doesn't say whether this is Pepsi compatable or not.

Ok, I have to make my usual peltier public-service announcement.
A while ago I got a new K6-2-300 with a peltier, even though I don't overclock (don't ask). I also started running Linux on this computer. After about 2 months, the computer stopped working. It would give me some nice not-at-all informative beeps on bootup and that's about it. I couldn't understand it, until I finally thought to take out the processor. It was green.
You see, most linux distros run the HLT command out of box, which is a command which "diasbles" idle parts of your CPU to save power (it's used in the Win9x programs Rain and Waterfall). But when you're using the HLT command on a computer which is idle a whole lot and which has WAY more active cooling than it actually needs, water will condense on your processor. Fortunately, this was actually covered by the warranty. But BEWARE!
Now I disable the HLT command and test Mersenne primes just in case!
Read this article I remembered a piece of email I received a week or two ago, these people do 25watt peltier units for £25uk or 4 for £89uk, 100 watts of cooling power on a coke or pepsi (lets not be colaist) is probably sufficient.
A peltier is the active equivalent of a thermo-couple. This means that there are two terminals and a voltage generates a temperature difference between them. Where as in a thermocouple the temperature difference generates a voltage.
One terminal is normally in a heat buffer of some kind (ice bath, flowing water, etc.). If the voltage is applied one way then the second terminal will become hotter yes. But if the voltage is reversed then it becomes cooler. This is because the first terminal cannot become hotter as its temperatue is buffered.
