Post Rad Chiller Concept

[ArtosDracon]

I'll stick with my simple ball valve. It has 1/4" BPT and no restrictions when open. And it was cheap - 9 bucks. Sort of like McMaster-Carr 4093T23 but 1/4 BPT.

I think I see what you mean, you're going to use a plastic wye and just shut off flow to the chiller with it in parallel to your main loop? You are going to use a second ball valve to shut off flow to the radiator right? If not they're just going to fight each other at ambient and the radiator is likely to have a lot more capacity than the TECs.

That would be soo cool to make a smaller version of that that could be controlled by a sensor that would shut off when it is within 2-3c of ambient temp, and back on when it goes above that. Would be ideal for overclocking and eliminate the need for insulating the tubes/motherboard since it would throttle back or shutoff when it goes to idle or low use (where the TEC would be cooling at a greater rate then heat is getting dumped into the water, which would let it go sub ambient and create condensation)

sounds like you guys are wanting to make a coolit system

yeah, but, one that actually works....

no such thing!!!! you guys need to read on heat pipes because they can only carry so much heat no matter how cool you try and make them. That is the downside!

Who mentioned heat-pipes?

Yep. I know it's wasteful to even mess with TECs but this way they will only run when I am playing with the OC. Under normal circumstances, I doubt that I'll run the CPU OC high enough to need the TECs.

Within limits, the CoolIt is OK. But I don't want to just have manageable temps at stock clock. I admit I've only glanced the CoolIt reviews for a number of reasons but I'd like to be able to run down around 0C and maybe get a little more OC headroom. I'll be particularly interested in playing around with it around winter time when the heat belching forth from the TECs can be put to good use. I used to fly scientific missions with 1KW of TECs venting onto the back of my seat. That's difficult to appreciate when the ambient temp of the plane is over 50C.

[littleowl]

OH my you have a lot to learn about tec if you think a coolit is ok! LOL

I'm VERY familiar with how heatpipes work but, what does that have to do with CoolIT stuff, everything I've seen of theirs is either direct die tec or a water chiller.

reading this morning I think I confused the 2 threads your talking in. It has been a long week.

I thought you might have been refering to the post with quad 6mm and quad 10mm heatpipes. Thats a funny thread.

[littleowl]

yeah that it is! I don't think it will work at all! but that is my opinion

[Clue69Less]

Go back and read what I said:

"Within limits, the CoolIt is OK. But I don't want to just have manageable temps at stock clock."

I've worked with 1.5KW TEC setups in scientific applications where detector temperatures needed to be held constant within a fraction of a degree, so I'd say I've learned plenty about TEC. This PC TEC stuff is fun and games by comparison.

LoL Guys NOL gets the package tomorrow.

And he will do the tests. So wish him luck.

I'm still getting parts together for my rig. I need to find a good low restriction two-way ball valve. The plan is to have the quiet, stock clock mode to run the CPU loop through a 3x12 rad. Change the position of the ball valve and the water gets routed through a dual-block TEC heat exchanger sort of like the one shown in this thread. I've got four 168 watt TECs and two 320 watt Mean Wells and another 3x12 rad to cool the hot side of the TEc block. It will be interesting to see what kind of temps the TECs will provide at load.

you have any pic's of that setup? sounds very interesting...

I like that idea of using the two way ball valve, that could be sweet

I'm still working on the case mod so the TEC parts are sitting for now. I'll start a thread when I get going on it again.

oh I missed that part about within limits.
well we are talking about duo and quad chips and there is no use for coolit products unless your only going to run stock.

boy it is about time Naekuh!!

[Clue69Less]

Those are exactly the limits I was thinking of.

[NaeKuh]

Package arrived @ Nols

Now i need him to respond on the status of the parts. The last time i sent out a ups shipment, they broke a leg off my RD-30 GRRRRR.

[KTE]

Nice DIY, at least you guys went ahead with the concept, one of few. Congrats, will now show us its plus and minus points better

I have to admit, theory doesn't favor the setup design for providing efficient cooling though. Don't really want to get in detail right here, looks like plenty has been mentioned already and it was only for practical experimentation, in which case... everything absurd to genius goes.

I'm going to be building on a sub-ambient thermal concept myself by December, but it doesn't feature TEC units at all.

[n00b 0f l337]

Status of parts?
Okay in the box; triple 120mm swiftech rad, 6 yate loons, the beautiful peltier assembly, meanwell, some wierd thin 80mm ish fan, a copper topped apogee, a laing d5 and I think thats it. Will be trying a few possible configurations, and most importantly will attach a ton of thermocouples and look like I'm doing something hard and technical.

Can't wait for pictures and results!

[hollo]

those water-blocks are quite epic

some day one of you guys involved has to try out 8 air-cooled peltiers. with 8 50W @ 12V peltiers + a 150W heatsource you'd have an average of (50 + 150/8)=68W output per peltier, which a $5.99 heatsink from newegg should easily handle.

with 40mm square peltiers + 60mm width k7 heatsinks you could do this x 2:

[littleowl]

Lets go nol we are all waiting!
