well, what did you expect, waterchillers aren't designed to take the water to below 0c because of condensation for one thing, and the whole freezing point thing as another. If you want to go below 0, you'll have to either use soemthing crazy like liquid nitrogen and use copper tubing instead of plastic to prevent extreme condensation from happening. That's why many people use phae changes instead for extreme cooling, that, or if you know the problems with tec and how to combat them, you could try that out instead and that should get you below 0, but as long as you are getting good cpu:water temps, I wouldn't worry about it

Tec's are over with. Phase is for a single source. Chillers can go to -what ever you want. You insilate accordingly. Don't take me the wrong way, I have read, and read, and read, and built a couple and have figured out the do's and don'ts only a little bit on phase and chilling. GL to you.

Cronos, are you the mystery customer for Drewmiester's new 3/4hp chiller over at EOCF?

It sounds eerily familiar...

No, i won't deprive me a joy to design and build this myself
I have joined the watercooling community 5 month ago. My WC cooled server is running non-stop over 3 month already and i am starting to feel very boring

[Pinmod]

is it just me or is chilled water kinda messy

[OCme]

It's not messy... you just need to insulate well if you chill below ambient temp.

[Pinmod]

i've just never seen one that looked "nice"

[Starkiller42]

That's because the builders are letting you peek inside of their units. Outside, they can look just as nice as any ss system can.

[Pinmod]

lol you mean like with the case closed an no windows? of coarse it would look fine

rofl lmfao


i could put a bag of crap inside the case and close it and it would look fine

[Starkiller42]

Well then, problem solved! Out of sight, out of mind...

AC Chiller; Build 2
Final build of my socket 478 chiller. Lazy & no oc benefit from subzero = no insulation. Thermometer monitored and ac unit cycled manually (via remote control).

[LRV]

Extreme machine 8-)

[Starkiller42]

Looks like a nice unit, Modzilla! I like the matching colors; makes a converted AC look a lot more professrional!

Go get some insulation and cover that thing up; we want temps! Tubing insulation is super cheap at ~$2 /6ft length at lowes.

[Gautam]

Modzilla's build thread is here and the title sure as heck speaks for itself.

This is what improper a/c chilling looks like. :-/ Can handle 2900xt's at -20 C liquid temp, x1900's at -32ish.

[Starkiller42]

Hey Gautam, as far as I'm concerned, beauty in function far exceeds beauty in form. And that chiller of yours is a beast .

[sssf]

thats a nice solution you made modzilla, what are your temps?

Depends who designs them and what they are for.

because of condensation for one thing, and the whole freezing point thing as another.

Insulate to stop condensation, add glycol or methanol to stop it freezing.

If you want to go below 0, you'll have to either use something crazy like liquid nitrogen and use copper tubing instead of plastic to prevent extreme condensation from happening.

Plastics are better insulators than metals.

That's why many people use phase changes instead for extreme cooling

Most chillers are 'phase change' (refrigeration) units, heat pipes use phase change, liquid nitrongen and dry ice are phase change.

if you know the problems with tec and how to combat them, you could try that out instead and that should get you below 0.

With the heat output on modern CPUs getting subzero on TEC is tricky with direct die and even harder in a TEC chiller.

but as long as you are getting good cpu:water temps, I wouldn't worry about it

Isn't lower temps and higher clocks the point of most active cooling methods and why we do worry about it?

Since my Swiftech MCW6000-NX hadn't turned up I needed something else to tinker with. I decided to explore the FSB limit and found it to be around 450. i.e. when the system temperature goes much above 40C I get 'delayed write failed' errors, choppy performance and the system often hangs. I got into windows at 480MHz. So the system can handle it if I can deal with the heat. So to alleviate this I followed up an idea I'd had for chilling the rest of my system partially successful experiment involved strapping an HDD water block to my RM1 and sandwiching 6 56/91W TEC1-12706 in between.

This is the block with the TECs:


The RM1 was plumbed into the main cooling loop and the HDD block took it's place in the secondary loop.

Some previous testing on these TECs had shown me that they drew around 6A at 5V. I was planning to run them from the PSU's 5V line but it couldn't source enough current. With them all connected it drooped to 4.4V and only gave a dT of -5C without the PC on. Basically it held the water in the secondary loop at ambient while heating the primary. Not quite what I expected from 112/180W of TEC.

So it looks like I need more power. An old ATX or AT PSU should suffice if I run it in parallel with the Antec. 60A should be enough for the TECs and the system. I tried running it off the auxiliary PSU at 12.6V but it got to hot for the RM1 to shift (6mm ID ports) and ended up with a positive dT.

What is the advertised voltage range for that TEC?

That's where I am, just a few months behind your progress, heh. 480x8. I wanna get it stable. Time for chilled water...

That's my chiller Made from an dehumidifer that cost me 10 EUR's: http://www.newwidetech.com/WDH-912H-916D-920H.htm

Orignaly, the look was:



Actually, didn't have to make much changes. The appearance is basically the same. Just drilled some holes, moved some parts, soldered the control chip and added a pump. Now it is easily connectable to any system. Because of a condensation, it has been set to keep the temp of the liquid between 12,5 and 14 degrees celsius. And because of a grate amount of liquid (8 liters), the compressor works only ~50% of the time. And it is quiet.

It is capable of doing much more. The test was made in August (+23c, 17l of water and no insulation).




New look: (I added thouse diods only because to have some resisdance for the tiny PSU I mounted under the hood).



It was possible (was, because at the moment I have a Prometeia for CPU as well) to cool down my E6700@3,8 Ghz, NB, SB, Mem and 2X OC'd GF6600GT.

Total cost ~50 EUR's

I'm just curious, do you guys have phase change for 24/7 run?

It can be or just for benching

[coo-coo-clocker]

@modzilla - that thing is a BEAST! Kudos to you.

The nylon strap tiedowns are a excellent touch.

O.o so much extreme cooling :P
nice setups !
