I still have plans but right now the money to carry out those plans is having to do other things.

 


It would be nice to have unlimited resources as there have been quite the interesting discoveries made in this thread regarding water cooling period, and what can be achieved past the daily traditional water cooling norm.

New discoveries and Solid confirmations:

New discoveries, in an alternative use of peltier cooling besides the traditional direct to CPU mounting for sub zero temperatures requiring insulating the motherboard to protect against moisture damage.

Solid confirmations, in the all around best graphics cooling solution regarding multiple full coverage water blocked cards is a large enough heat dissipating area radiator.

I have to hand it to my wife as what I do computer wise is a hobby to me she has stood behind me even though she doesn't understand my desire to discover, even though there are more important things we both want to get accomplished on our home and such as that.

So my experimenting goes to the back burner of the stove but I am continuing testing every day this setup is operational up and running, testing the time dependability of this type of peltier cooling, which so far has performed consistently and dependably.

I got another confirmation yesterday that going from freezing the ice blocks using 2 freezers daily, (where this thread started.), to the peltier cooling uses $50.00 less electricity each month, plus has eliminated the changing of the blocks, having to open the cooler top and allow dust inside, and having to use a filter.

My goal in this search for a better way of doing it plus still have the 10c water temperature target goal has been accomplished better than expected.

I'm enjoying below ambient CPU cooling above the condensation point with temperatures you just cannot get with traditional radiator water cooling.

My overclocked CPU runs daily cooler so if keeping it cool extends the overclocked life you cannot ask for much better and get it without an extreme money investments and all new problems to solve.

Am I done experimenting? Absolutely not!

Just the fact of discovering something successful is incentive enough to continue whether anyone else is doing the same or similar, or not, but experimentation cost money, and that's where this post started. :)

 


I'm wondering something here, did you ever try doing it backwards and putting the radiators into a refrigeration unit so that the water in the closed loop could cycle through there instead and be cooled that way? It would eliminate your need to change out the jugs every day and no longer would you need ICE. You'd just have the radiators in a mini-fridge in the freezer or something and the closed loop would run through that into your CPU/GPU's.
 


No I never tried that.

But I did try porting the output from an A/C unit directly into my computers intake air cooling, the problem was there was no constant to depend on, as the cycling on and off of the A/Cs compressor yielded a fluctuating temperature which was not dependable. The A/C wall unit is designed to cool an entire room but to do it over time and the cycling on and off do not matter regarding an entire room, but did matter as a cooling source for a computer. In the same respect the refrigerator or freezer is designed to cool the space area inside the insulated box, but it is designed to drop the temperature of anything inside slowly, a radiator from a CPU is transferring the heat produced from the CPU to the inside of the refrigerator or freezer causing it to function past it's cooling capabilities.

Neither a refrigerator or freezer is designed to cool a heated source, it is designed to basically cool something from ambient room temperature down to whatever temperature it is set to run at. Putting a radiator inside is a constant heat source causing the unit to run on high to attempt to cool down what's in it.
Many have tried it but no one has written a guide to doing it as far as I know, or as to whether it was successful or not.

However, Why don't you do it and tell us how it did?

Regarding the quotes taken from my statements, they are regarding if you're already chilling the water to below ambient and then running the chilled water through the radiator, the radiator defeats the chilling because they are an ambient cooling constant, because that's all they have to cool with, ambient. If the ambient is a higher temperature than the water running through the radiator, the radiator heats the water to as close back to ambient as it can. The radiator is just a heat exchanger it has zero cooling capabilities of it's own, but where you put that radiator can make a difference, say if you stick it outside the window on a 5c day.



 
Or permanently like Uther did, fixed his rad to his carport wall hehe, good man that one
I'm not surprised to read 'Am I done experimenting? Absolutely not!'
each success just pushes the realms of possibility a little further imo, lets keep going until the day we are waiting on Cpu manufacturers to release a chip that can live up to our cooling :)
note to intel, you'll be wanting to use decent paste on your lids from now on yes?

May have been an Intel plot to get out of honoring a lot of 3 year warranties, just let it slip the CPU could be delidded for better load temps and watch the voided warranties go out the window, when all the delider really needed was better cooling! :lol:

 
Yay! conspiracy theory :)
/draws on rollup...
Its their plan man, they want you to pay like, for the chips performing at a substandard level so you need to buy like, a higher level of chip feeding their machine of money and power, its the man trying yet again (Draw) to keep the average clocker like you (draw) and me under the oppressive heel like, of the system,
Its like, an endless cycle to get caught in man (draw,burns lip)
well I ain't gettin burned no more brother, no more I tell ya....
:)
Its great in my head lol

Wow. You guys are impressive. Someone really should hire the lot of you as engineers/prototypers, and fund your collective insanity. I'm sure they'd get the better end of the deal, regardless of what they paid you.
 
Its been suggested before that Ryan, Rubix and myself meet up, whatever came from the meeting would likely get them arrested on the way back into the US though :),
throw in Boiler1990 and Lutfij and you'd have some serious R+D happening :)
If the moneys right I'll take the job though and thank you for the compliment

Collective Insanity! :)

That's a good way to put it!

 
Hello again 4ryan
I just recently set some something vary closes to this based of your idea here.

I am using a 5 gallon ice chest, and adding 1 gallon of ice or 2 two liters bottles of ice every 2 hours but I also have my gpu cooled in this loop. At first I tried to add a rad to it but I found that it was not working well my rad is 420 and just too large. I also have a bay rez pump combo, so I ordered a few d5 replacements kits that come with normal housing and mounting kit for it because that bay rez causing a few problems from time to time……… daily...

My question is about flow-
1 I have a Ray storm and I want wondering if you ever took off the restrictor plate out of your rasa and went full flow. If there would be any benefit to do this on a Ray storm.
2 Oh yeah one last question what filter are you using for this idea I ghetto rigged one after about 20 attempts that stopped my flow
These photos are from day 4 last week after my first attempted didn’t work out and remember your idea of not using a rad.



I ran out of tubing so I ran to lows and grabbed anything I could find I am replacing it this week once my order gets here.

That top is from my botched job of laying it down sideways. luckily I had 2 from my time in the military... lost one of the tops somehow... lol

painting goal was to make it look metal... and give it texture..




 


It's nice to have another crazy added to the club! :)

From your pictures it looks like the hoses going into the cooler are just looped inside as one hose not cut in too, is that the way it is setup?



The XSPC Raystorm is already a great water block, less flow restriction than the Rasa with better cooling performance.



I used the filter setup in the beginning of the thread it is made of nylon mesh, to attain almost unrestricted flow rate I bonded 3 of them together using JB Weld, they worked fantastic.

 
The tubes go in to holes I cut in the lid of the ice chest.

Thank you for the info about the Raystorm I just assumed that because cpu block is cold maybe better flow might be better. I also have an Indigo Xtream on it not sure if that makes a difference.

What happened to the forms no water cooling section there all in tags now?
 
Do you have some way to monitor your actual water temperature in the cooler?

What kind of CPU idle and load temps are you getting?

The forums is all flipped upside down now with this new software, you just have to find what you're looking for.
 
I have not monitored the water temp as of yet however I do plan on buying a temperature monitor once I get I have extra cash not sure what kind of to get yet (led interface or not). Idle temps on my CPU cores are 2-12 core zero then 12-20 on the other cores. GPU sits at 17-20 degrees idle, Load temps are highest core is at 40 not overclocked gpu load is at 50. I could not remember my settings of my overclock so I was waiting to finish the set up. And do a bit of research again. My brain forgotten how to overclock my cpu after doing this cooling solution (LOL) Like the episode of Married with children where they teach Kelly how to win on jeopardy but she forget something every time she learns something new (LOL). I have not had any condensation build up as of yet. I already have the insulation sitting on my couch I have not gotten around to adding it yet.
 
The most important condensation area is on the water blocks copper base plate backside and sides and at 2~12c you will have some condensation.

The backside of the water block you cannot see and the condensation forms around the outside contact area of the CPUs heat spreader, on the copper itself.

What CPU water block are you using?

An additional fan blowing directly on the water block will help to evaporate the condensation, but if you're down to 2c CPU core temperature you are definitely in condensation territory, so be careful.

Like the episode of Married with children where they teach Kelly how to win on jeopardy but she forget something every time she learns something new

:lol: I remember that one! :lol:
 


Another option that you can use is foam, that's used for extreme cooling and it¿s perfect for avoid that condensation problems.
 


Hi German, That may interest thegun because with his setup 0c is reachable, how difficult is it to remove the foam or is going that route permanent and a warranty void of the motherboard? IDK?

I presently enjoy operating in the above condensation forming in the 10c water temperature range which is usually in my situation 13c below ambient, that's what the TEC cooling has allowed.

Where I live condensation doesn't begin forming until I reach 8c water temperature and appears as a fine frosty look, it worsens with every 1c drop from that point and at 5c water droplets are beginning to form, (That's Bad!), so operating at 10c keeps me well above the condensation forming problem.



 
I was going to use kneaded eraser rubber over the part of the Mobo, and the gpu thanks for the info.
I am using a ray storm cpu block. oc cool gpu block.

I don't think 0c is reachable I think that is just a faulty temp on that one core. the other cores are around 12*
 


Not, the foam is easy to use and remove from the board. The difficult to remove is the eraser. With both, your warranty is void, even, we both know that with just remove the socket support and back plate the warranty is void.

I'm not sure that cooling method is he using, but I´m not sure if can be easy get a 0°C with chilled water.
