Water,or any liquid, is not an optimal cooling solution. Too complex,
prone to leaks and an enginering nightmare. I am surprised that overclockers and computer cooling freaks haven't yet discovered Peltier thermoelectric heat pump chips.

Unless you have a very large heatsink, peltiers are useless for CPU cooling.
You have to DO something with all of the heat that is being pumped from the other side of the element..... Last time I messed around with that, a small 30-40Watt peltier required a heatsink the size of small novel to even be effective and keep the heat from going back over to the other side of the element. This was back when CPU's only pumped about 50Watts. Nowadays, it's just impractical. So, basically, peltiers came and went. Old-school. Yesterday's news. Etc.. - Beowulf stood up, at show-n-tell, and said: Water,or any liquid, is not an optimal cooling solution. Too complex, prone to leaks and an enginering nightmare.

I think if you investigate you will find that most overclockers who use Peltiers these days (there is nothing new about their use in overclocking) water-cool them. With a Peltier you're dissipating the heat generated by the CPU and the additional waste heat generated by the Peltier. If you can't cool the CPU without the Peltier then you don't have a chance in Hell of cooling the CPU _with_ the Peltier. And Peltiers introduce their own complications. raj wrote: can water cooling cause corrosion, cause I will be water cooling my gf3 card as a test, then i will use my radeon 9700 pro AIW if the out come is good -- -- --John Reply to jclarke at ae tee tee global dot net (was jclarke at eye bee em dot net) |

No corrosion if you are using distilled, de-ionized water.
H2O is not corrosive, just some of the dissolved and suspended solids are. "J.Clarke" wrote in message ...

Didn't I read somewhere that peltiers cause condensation around the CPU? I'm
pretty sure I did. Pete "J.Clarke" wrote in message ... On Fri, 27 Jun 2003 21:48:43 -0600 Beowulf wrote: Water,or any liquid, is not an optimal cooling solution.

No Peltiers don't need big heatsinks - that's a misconconception and a
design flaw. They aren't popular since they were initially introduced prior to the Pentium1 (several patents were filed); however, passive cooling in those days was more than adequate. Passive cooling needs big heatsinks - even with big fans - with today's CPUs. You will still need to put in enough case fans to exhaust the heat your pulling off. The biggest mistrake poeple make is not setting the heat pump voltage properly or choosing the wrong heat pump. Many people erroneously think that in order to cool the CPU (overclocked or not) you need to chill it. You don't . You just need to drop and regulate the temp to 15-20 degrees celsius - and thus no condensation. These devices are extremely efficient and effective at cooling. I have had great success with them in the past. - not just for CPUs, but also for a variety of scientific instrumentation. I don't use them anymore simply because it is easy and relatively inexpensive to pick up a faster CPU, mobo, and/or graphics card. Although I do a bit of gaming, mostly my PC runs office apps, www browsing, a few DVDs, and some video/image editing, I only see a small difference real world performance in overclocking. With 3GHz CPUs, most tasks are done before I can reach for the mouse - anything that may take a few minutes just means that I can check my email or go take a **** while I'm waiting. Going faster the 100-150fps in an OPENGL shooter at 1600x1200x32 full quality, FSAA 4x, etc, is just a bunch of weenies saying "mine's faster!" So what? I used to have the same discussions with motor heads over whose car was faster. Big whoop. pete wrote: Didn't I read somewhere that peltiers cause condensation around the CPU? I'm pretty sure I did.

"pete" wrote: Didn't I read somewhere that peltiers cause condensation around the CPU? I'm pretty sure I did. Depends on how cold you're running. Any time you're running below ambient temperature there is a possibility of condensation. There are ways to deal with it, generally involving an impermeable barrier of some sort.

Yes, they are efficient and effective but they still must dissipate not only the thermal energy produced by the CPU but also the thermal energy of their own power consumption.
