TEC watercooling loop

[spwath]

Would it be possible to have a tec, with hot side on water block, cold side on CPU?

Would I have to do some sort of insulation for condensation?

[Levent]

thats what people do actually and I have seen people do it without insulation and some with insulation as well I guess its all about the power of the TEC.

[thekeemo]

yes not worth it though.I like having a waterblock on the CPU and the TEC away with its own heatsink.

Not expensive

either way you get the same cooling...

except with your way you need to use condensation proof tubing

if the tec turns off during low load then its not necessary, but if the cold side goes below ambient then yes you need insulation

what is a TEC i have not heard of it before 

[Naeaes]

A Peltier element? A bit early 2000's IMHO, but it's doable. Here's a good article. Condensation will cause problems if you dip too far below ambient temperature. With peltier that can happen.

Ok, kinda like what they did in phase change cooling?

And would I be able to get sub zero?

I mean, I don't need to, but that would be pretty cool

digitalstorm uses a cry-tec system that gets them below 0

the peltier unit is in the waterblock, just like youre planning to do

 

they must have used a multistage peltier to get those low temps, I think with a single stage you only get a few degrees cooler, it depends on the power rating

there are some more powerful than others

 

TEC is completely different from phase change

in a way its more simple and easy to set up or DIY

I don't get it, in the artical linked below they said don't water cool hot side due to heat, air cool it.

That makes no sense.

And I should be fine having it directly on CPU with propper insulation?

Yeah I meant in the insulation sense.

whoever wrote that article is an idiot

 

yes its fine on the CPU with insulation

 

there are plenty of yourtube tutorials on TEC cooling with a heatsink

all you gotta do is replace the heatsink with your waterblock and youre good

Ok, thanks.

I'll see how much it does, it will mostly be for fun

[Enderman]

yup

oh and you dont have to do such a huge mess like linus did when he did the TEC

just some insulation foam with a square cut in the middle will be enough

Ok.

 

And what kind of wattage TEC should I look for?

[thekeemo]

Not expensive

  forgot to mention the hassle and worry I had a mini loop running on a spare system for a while.

I had a system that turned off just above ambient

[Benji_w]

Ok.

This is the wrong place to ask, go to OCN and get proper info.

I would go for as high as possible...

Yeah ok.

I never know how to work other forums

[iamdarkyoshi]

Wow, if you manage to get this card to sub zero temps that would be hilarious! Keep in mind that TECs are only 8% efficient, the rest is turned into heat

[Benji_w]

Yeah ok.

Great thanks I'll give that a look

sorry to kick a dead thread, but i do have a few questions of possible solutions i have been mulling around with. the idea is basically an independently powered system containing 3 reservoirs/pumps(DC 12V 1.1A 13.2W Brushless Magnetic Drive), 7 water blocks (3x cooling chambers for coolant, 4x for direct cooling of TECs or 4 heat sinks depending on what method is best), 4x TECs and a power supply. the cooling chamber design i was thinking was sandwiching 3 blocks together (like 1 block with 3 chambers), and having a TEC on 4 sides of the block

cooling block:     _|   |_ _|   |_ _|   |_  

                           | gpu | cpu |mobo|

                    TEC|        |TEC |         |TEC

                           | ____|____ |_____|

 

im not sure how clear that is but thats the basic design. so major concerns right off the bat 1) power: what PSU would be best? is there a PSU out there that can handle 7X 12v out puts? what would the over all resistance be? 2) condensation: will insulating the cooling chamber output tube solve this? should i be worried about condensation on the transfer plates on the main computing components? 3) water cooling vs heatsink air cooling the TEC: would creating a decent air flow ( with independent input and exhaust)  through all the heat sinks be sufficient or could i add 2 additional block nodes to the mobo flow system and gpu flow system to handle all 4 TEC's cooling before heading in to the cooling chamber ? 4) temp control: could i possibly slave an arduino to extrapolate the temp control output from the mobo, to control the temp of the TECs? 

 

right now the goal temp at transfer i want to get to is 1C-6C. i know this is over kill, but i want to be able to keep the pump and cooling out side of the main case (im already uneasy enough using liquid cooling, so i want to keep the reservoirs outside of case just in case of leaks, pump malfs and tank cracks). also i am favouring  independent operation managing over integrated operation through the mobo so no worries if i cant slave. once again sorry to kick a dead thread, but this was the first search result that game up when i checked this website. thanks 

 

P.s i am working on a non detailed block diagram for this, i'll post it later when its done
