Me too. Get a piercing valve and a set of gauges. Then after you get it tuned, we will talk about changing the cap tube to make it even colder.
What guages exactly..and ill see what i can do
Something like this:

This site also has gauges. And piercing valves as well. Click on "product locator" and "line piercing access valves".

With these type of chiller setups, would a pestier be of any assistance in lower temps on the chip??
If so what wattage for the various chips?
Thanks

Insulating every square inch from the compressor to the coolant level has helped a TON. -41C right now!
Oh..and damn girls..my wife told me to stick my tongue to the block to see how cold it was....well..i am from Northern Mn, i should know better then to stick my tongue to metal thats -40, well, not thinking because it was so small and in my house...i tried it OUCH!
Anyway...it is awesomely cold, i just can;t convince my cpu to work correctly. Gonna try a different motherboard tommorrow.
Where can i get vacuum pump things and fill gauges in aus?
I take it the evaporator is still laying flat on its back, and your saying" there seems to be an issue here". There is an inch of frost on your lines. your loosing cooling power and yes you can lose that much cooling power to a cpu its happining.Sounds like you need more evaporation to go on in the evaporator and a little less everywhere else.Quote:

Ok, there seems to be an issue here...is it possible that due to the ince of frost...lol..yea seriously an inch....on the pipes before the cooler that I am losing alot of cooling power. Yesterday I had temps of -34C. Right now I have temps of -15C. The CPU has been on but there is no way i lost that much temperture due to the CPU. Especially since i have 5 gallons of fluid in there.
Does frost on the lines take away from the end result coolness?
Yea i did an insulation job and i did it the xtreme way..lol...two layers every square inch of piping..lol...i have gained(lost..however ya wanna see it) considerable temps! At -41 right nowQuote:

Conflict, that with direct die with your ac unit?
Nope it isn;t a direct die yet!Quote:

Just a plain ole waterchiller
And what is it doing at idle? Or fully loaded?Quote:

With a chilled pelt you can kick @ss. Your pelt still needs to be the right wattage for your heatload . I did some experiments with a 50 watt pelt just to se what it would do unloaded .Quote:

Well my motherboard bios doesn;t show anythign below 0C (32F). When anything is below that it just goes blank.
And when i was downstairs testing it was blank. Im not real happy right now because I screwedup the hard drive. After my first attmept at raising the FSB from 133 to 160 it posted and went into windows. Went back into bios after restarting and it showed 3C. Took the next step and tried doing 175 it started to load windows...after the final loading screen I got a blue screen error claiming Inaccessible Boot Device. I am reformating and installing windows right now to try again. No idea what happened.
Coolant temps is still showing -41C. I am not sure if the CPU will put off enough heat to raise the coolant temps that much.
OK...well I went out and bought a real temperture monitoring device from the hard ware store. It only reports Farenheit tempertures but at elast i know it reports them accurately.
And im not real happy ...it is only reporting -4F in the coldest spot i can find in the cooler.
I guess I was hoping for much more cold. Any tips or tricks....i mean it still keeps my CPU below freezing...but there must be a way to get colder temps
Well, Lets see,hmmm? Oh yea , maybe having your evaporator laying flat on its back in the bottom of your res could be the.... No wait that cant be it .lol.
lol...yea yea yea....if i had a way to move it i would
But really....how much of a difference could it really make how it is situated...the refrigerant is still evaporating...
I believe with some creative thinking you could find a solution.Still evaporating yes ,but ask yourself where? You want as much of the refrigerant as posible to evaporate where it was intended and where you have your coolant .http://www.phase-change.com/phpBB2/viewtopic.php?t=1187
Well i turned everything off for tonight...i think tommorrow I am gonna try to at least bend it to a 45 degree angle
:stick: Hehe, yea ,just sit and look at it for a while something will come to you , also if you raise the coolant level think of something to to displace it so you dont have to add more ,you may even find a way to use less coolant through displacement .Don't expect your temps just to drop a bunch I don't think it will do that but I do think it will help you with the load it will handle, A lot of the guys I see with AC chillers get around -25c coolant temps as they are overcharged as Gary keeps reminding us we wont get the real drops till we tune our charge.Quote:

I don't believe your new thermometer. But then, I didn't believe your old thermometer, either. Try them in icewater and see if they are somewhere near accurate.
More importantly, the compressor isn't safe from floodback. I'm thinking your system has an accumulator in the suction line. That is the device that is saving your compressor. I don't recall seeing one on conflicts's system.Quote:

What dont you believe about the new thermometer? Do you think it is lower or higher then that?
This is a Taylor temperture probe that is suppose to be used for liquid temps. I got it from the hardware store and my cousin whos dad owns the local refrigeration place reccomended this thermometer...so as far as I am concerned it is right.
I stuck it outside the window and it is reporting the exact same temperture as my outdoor thermometer and the weather channel are reporting.
I spoke with chilly1 and he said that i should slightly pinch the cap lines going into the evap and that will help me to drop the temps. I guess I didn;t totally understand the reasoning but I trust what he says so i think im gonna try it tommorrow after I rebend everything to its final resting spot
I think someone who knows what he is doing could make the cap tube pinch work... sorta. It is not something I would recommend to anyone.
well....given the extremely basic tools and knowledge I am working with...other then setting the evap slightly upward...what would be a good place to start with in tuning this system to drop temps?
