im not disrespecting you or anything but , what was atractive from the Mindchill offering , was THAT controller . if you can emulate that or acquire his design ... you have business !!!! , im in process of making my own cases this summer ;_;

No disrespect received. I plan to develop my own. Going to also be writing software so it can be controlled from windows, possibly with temperature curves or load adjusts. Its a really early idea, but it should be an experience even if I don't make it to the end.

you and Mindchill work together ? if so ... why cant you keep the store ?


... i feel sad because this Tec thing is a great idea and the solution you guys created was so simple and unique , that its a shame its not mainstream or at least known enough to get some creativity in this "niche" (not saying that there arent any but the more people know this , the more people will be interested and the more interested will develop and so on and on)


i have some ideas and some "proposals" here where i live , and i would love to implement TEC into this idea of mine , i could PM u a render if u want to get hyped biggrin.gif

Mindchill was the one that designed everything, owned the equipment. I was just incharge of the webpage and sales, and a small helpin hand with 3D modeling. I will eventually be taking it over, it's going to be a while until I have the equipment for it. Also things will be shipped from Canada at that point.

Yeah i am pretty shattered that his TEC blocks and controllers are not going to be in my build.

Does anyone else make anything similar?

Where is Jack aka Mindchill, the TS?
I couldn't contact him since 3 months ago.
I got one faulty Quad TEC sent for him back for RMA replacement in July last year.

In Dec he agreed to refund me at least 70% as he couldnt get the things fixed after few months of delays.

I've also contacted his sales partner Mr Krow but seem that he also couldnt reach Mindchill.

Really interesting stuff about TEC here! I was thinking though would it be possible to have a kind of combination system operating with the TECS? For example having them arrange in this order....

Let say 3 loop system. Water cooling the first set of chillers then those chillers cooling the water block with a direct die Tec onto the processor through a design water block.

Basically be room temperature so the water cool loop should be around 25c then placing that loop into the first set of chillers bring it down to below -25c and another set of chillers been fed into another chilling setup... Say below -75c liquid which then get fed into the TEC waterblock would you be able to achieve say sub -100 temperature with that arrangement of temperature?

I'm just extremely interested in TEC as I'm looking to spend a lot of money on my next computing build implementing TEC and if it could achieve the same performance as two stage phase changing without the dreaded noise would be awesome if you can chain the 3 sets of chillers together then the super cooled liquid right onto the TEC water block which would be drawing heat away from the processor back into the loop that is chilled.

I don't know if all that is possible or not since I have no real experience in TEC and there limitations though I have been doing a lot of research however I don't know if I got my math right tongue.gif

Cascading TEC's is very possible, but it is extremely inefficient for the power used. You are talking hundreds and hundreds of watts to get sub zero load temps, and lots of money in TECs and cooling gear. At that point, phase may be the more logical alternative.

If you just want better then water temps for a 24/7 use system, running a direct die TEC is great and fairly simple if you are already watercooled, and throwing a chiller in line with it will help even more if you have the room for a second loop smile.gif.

^^^ Puck is correct in what he says above. Also what kind of coolant would you use, I seem to remember an earlier post that had a coolant with an extremely low freezing point. the problem is at those temps it was more or less a gel ! Which brings us to the next problem, that is the pump and how it will react to those ultra low temps. Most pumps will not even start up because of the torque needed to push gel around, left with power on they would quickly fry from the current draw. If you were to do this I would take Puck`s advice and optimize some sort of dual chiller or chiller - direct die combo. Myself I will be doing a dual-chiller with a total of 4 Tec`s and hope to get down to -20 or -25 C. Keep posting we would like to see what you will come up. Best of Luck ! thumb.gif

So better than two stage cascade phase change cooling is possible with just using a combination setup... Well that good I mean that revolutionary and pioneering to the extreme is just what I’m trying to achieve with of course without making the hundreds of mistakes that everyone else had made keeping them down to a dozen hopefully. tongue.gif

At the end of the day all this is just a hobby for us, but our hobby and taking new and more extreme measures in keeping our little tiny processors cool is all going towards future developments that may or may not be implemented in future stages. We are all pioneers those that making custom controllers, programing to control when and how or what temperature targets the TEC is going to be used to cool a certain temperature at a given load….
90% of the average people will just go wow can’t be that much of a challenge? Because most people just think TEC are these magic heats absorbing devices… In a way they are because they emit zero noise have a combination subzero setup; couple with a direct dies TEC. Main is to design a system capable of going below -100c even though it will be more then capable of reaching -140-150c at even normal room temperature with such a setup to dropping down the room temperature by a further 20c close to zero one could even reach liquid nitrogen specs!
However specialized insulated piping right now I can get my little hands on goes below -60 but the 3/10 ratio of Ammonia Hydroxide and Distil water in the final chiller loop only that will be completely sealed and sealed again… Insulated around then cooled by a set of chillers so it’ll have a boiling point of 27c a little higher than room temps if it was exposed to air, with a freezing point of -91c. Just worried about a number of things like if the insulated piping will hold out for another -20 to -30 to get the extreme, extreme temps.
Valid point about the pumps be using double pumps capable of 2400 liters per hour but no way a system can even flow that fast through anything so be reduce to 60-80% still getting way above 1500liters per hour and gives the pumps a little head room. Basically series 3 times 2 double pumps. For the normal water cooling loop be super large quad radiators and ultra-thick bad ass. Two time 480mm that 960mm plus another two times 360-380mm radiators for around 1700mm total radiator might add in another 140mm to the exhaust if it needs it… (1840mm total) Those would cool the motherboard and quad sli or crossfire graphics which ever becomes better when I finish this long project build. Primary reason why I have so much super heavy radiators that are going to be attached to super high fans in push and pull configuration is that I’m really serious about pumping the first series of TEC right up so it gives the second series of TEC a little head room.
Wanting to keep it around 4000w with duel 2000w PSU but might have to put in another 2000w unit…. No idea where I’m going to put that in the case or might have two small 1000w something but wanting to keep the power connectors down to 3 or less. What the point of having quad power connectors rather than a headache. Other option is buying a server psu rated over 4000w at triple the price. Anyways better get back to work the actual work not this side project fun stuff tongue.gif
