Og Big sturl, du er vel ikke tilfeldigvis Sturla?
Hehe, jo :) Det vil si, jeg heter Sturla. Forøvrig finnes det også én annen Sturla som driver på med fasekjøling, nemlig Stoolman. Da både navnet Sturla og fasekjøling er nokså sjeldne ting, så tror jeg ikke du finner de to i kombinasjon flere steder (hvis jeg ikke tar feil).Quote:

ok, hehe, kjenner Stoolman via kona hans som er venninde med ekskona til broren til kona mi.... LOL ! Men holder du til i Oslo?
Vi tar det over Pm, ok? Orker ikke whinete mods.
Ok, mr. moderator, we'll take it over PM.
sorry, have to say it but you said "stoolman" and in english that means poo man
yes, thats his nick.... his kind of humor.. :)
Aiiiiiieieeeee! Stop with the Norweigish! I can't understand you!
heres some picture of the progress. Below you see the covers painted, the box itself painted, front cover of insulated box with the foam seals mounted with silicone, and a homemade cable extention for mobo power hookup, the socket was ripped from an old mobo by heating it on the stove and ripping the socket out... smelled really good ! then soldering on the cables ripped from an old powersupply...

Tomorrow Ill probably will be done with the last gluing stuff, and mounting the different switches. also need to make an extention for the aux power cable, and routing them together with all the other cables that go to the motherboard... hopefully ill be ready for a testrun wednesday, but... its slow... :)
i just thought about your idea with heatload testing and think about lightbulbs, not all 100watts of a 100 watt lightbulb are turned into heat
Well, most of it is, as the part that is light turns to heat as it is absorbed by the surroundings. In a closed box, no light of the spectrum we see escape, but a really, really minute amount might be part of the spectrum that can pass throug walls of some thickness. This is most certanly less than 0,01 %.
Another thing is that the voltage might change from place to place, and hence the effect, but the difference is less than +-10 % i think.
I thought 95% of the light bulb is wasted as heat
k nevermind, just popped into my head
did a load test with my current setup ( athlon xp/ sempron) abit nf7-s and radeon 9800 pro in the rig. I have some fluctuations in temperatures, but it seems to hold off the load, and I noticed that the cooling capasity increased a bit when I managed to seal up the "suction box" ( where my fans sit and pull air over the condensers)
hadnt hooked up the ide disk correctly, so I did not get a full load scenario, just booted repeatedly...
had -11C in the box ( temp probe is flushed with air from the cpu hs/fan) and mobo reported 15-16C degrees on cpu.
It operates quite silently, the most noize comes from the powersupplies.
Im gonna put in a bottle of Cooling liquid mixed to freeze at -12C to get a little buffer for higher load over time. Tonight I might get a better picture of how its going to work. Crossing fingers.... :)
I think 99.999% of the energy going in to the lightbulb is relesed as heat, rest as sound. I am not sure if light falls in your standart energy group. On one hand photons have mass and can have a velocity. Hence they can have kenetic energy. But that has nothing to do with actuall light. I should ask my physics professor tomorrow.Quote:

It might not be considered "energy" itself, but it most certainly is a good carrier of energy. We do for instance have a rater large orb in the center of the solar system (the sun, I think its commonly named) from witch we get almost more energy than we can handle, all in the form of light, or radiation.
Depending on the amount of energy each photon carries, it has a corresponding "wavelenght" and also the speed is relative to this. Likewise the mass corresponds to the amount of energy.
Depending on the wavelength of the photon, it has a certain chance of being stopped in, or, deflected off the medium its hitting. Some mediums, like air and glass lets some wawelenghts pass, and others be absorbed or deflected. Thats why we are not toasted, and still get some light down here.
Now:
1. All heat radiation is happening in the form of Photons leaving the body radiating the heat.
2. All bodies with a temperature above absolute zero radiates heat.
With the examble of a lightbulb, it is safe to calculate with 100 % energy going into the box, unless there is a window in it.
FYI Didn't every one notice the compressor is using an ebil flammible gass ie Butane ;).
I think you're going to have some load issues.
Yep, I think there might be some load issues... I hope to get enough buffer headroom to get some decent continous low temps.
Getting closer to do a real test, pretty much finished now, only minor adjustements to do before I can take it down to my office/ kitchen :)
And... its in my living room, testing it out...
Had some windows issues ( from earlier on) , but they should be resolved now, so I can start testing the system for real pretty soon.
Had it up an running on a Spec viewperf benchmark for an hour or so to test how it handles load, and it seems to be kind of ok. Tempratures gets stable in the -7.5 to -8 area. This was with just a mild overclock, and a little extra voltage, so I am not sure how it will react to more oomph.
My delta t between air temp and cpu temp is somewhere near 25 degrees, so, cpu temps is less than impressive at the moment :) but I think I can get it a little better by some adjustments.
Temp regulation of the system is kind of difficult, as the thermostat shuts on and off with a delta T of 15 degrees. I have to take a look at this to see if I can get that window a little narrower. As it is now, it shuts off at - 25, and on at -10. I dont want it to get much colder than -25, but my buffer Ice has a freezing temp of - 12, so i would like the system to start at -15 or lower.
Now , for tonight im gonna test some more, and also try switching the fans over to the 12 volt rail to see if added air flow has any effect.
Ill try an post some pictures soon :)
if u find it unsatisfactory when done mod it in a submerged system!!!
gretings,

I have thougt about that, and find it kind of intruiging, but its kind of messy...
Thinking about making my own heatpipe cooler (mostly to test the principle) for the cpu... hehe..
Anyone tried making their own heat pipe?
You'd need a vacumer to be able to produce a heatpipe wouldn't you? That kinda stuff is expensive to say the least. I know overklokk has one, he might be able to help you (with that, and pretty much anything relativ to phase cooling).
Nice to see more Norwegians here ~_^ I'l keep this english out of respect for the other readers however.
I havent quote made it into the phase cooling scene yet, but I'm pretty confident I can surpass a lot of you phase cooling guys with my new übar TEC/water system thats soon done =)

Looking pretty good.
Maybe in complexity, but not in temps ;DQuote:

And please note however, I did say I'd beat -some- (EDIT: well no, to be presice I said "a lot") of the people using phase cooling. Not -most- and certainly not -all-. I am quite aware of the limitations of TEC cooling, but I do expect to be able to hit full load temps of somewhere between -15 to -25 (calculating with an overclocked conroe as load). I've seen plenty of DIY phase cooling projects that don't hit sub-zero temps at load on the other hand.
Theres more to my new cooling system than just a regular water loop + a TEC, otherwise I wouldn't be mouthing off ~_^
