I think the solution here for me ,is to go ahead and do it ,especially since i already bought all the parts ,there are pro's and con's with any of the setups so really no matter which way i was to go ,there would be downfalls with any of them .
I am happy with the plan of action i have for myself and the desk has performed fantastically so far ,this is a prototype project for me and when i get the whole thing done ,i mean the TEC'S I will then try to design the same system ,but in different materials for the desk ,something lighter .the temps i have just on air and water are fab ,my cpu idles @09 deg
http://dl.dropbox.com/u/7112696/Desk Project/9 deg c.jpg
so i know i have succeeded well here .
Thankyou for all your comments and i will keep things going ,as soon as i have the blocks and tec's back from the guy who is making them i will continue with it ,in the meantime ,thanks again for all the comments.

Oh yeah i forgot to mention ,here is my best oc soo far on just water and air ,for this chip ,not too bad i think

Here is a case that used TEC's and looks awsome http://www.bit-tech.net/hardware/pcs/2009/10/23/scan-jellyfish/1

Yes ,nice case ,but in my setup i have twice the res ,twice the rad,twice the pump ,twice the psu, ,i have made the system the way i want it to be ,with the option to fit "LOADS More "in there if i wanted ,plus i dont do ,"Towers" ,they are a restrictive form ,the desk pc that i din ,allows for scope on the build,total desktop clearance ,no metal cage down the side of the desk ,or blocking your feet.
I do like the detail in his case ,but i am also not one for arty designs on a case ......
Also there is an old saying ,that heat rises ,even a little bit of heat would still get to the res at the top of the case ,so thtas another reason why i wont ever have a case again ,restricted on where to put things and you end up just doing what others have done ,thats why what i have achieved with the Custom Desk PC makes me smile everytime i sit down to play .There are some fab designs out there especially the japanese wooden cases ,sooo much detail.
Must get the kids up now ,its that time again.

It's very original - good work mate!
Writing off tecs on the basis of electric inefficiency relative to phase is a bit harsh. Peltiers offer significant reduction in size, not needing a compression, and indeed not needing to do anything difficult with refrigeration in general. I'm more interested in thermoelectrics than in refrigeration because small and no moving parts both sound like excellent attributes.
*Bangs head into desk*
That isn't a specification. It's vaguely equivalent to "what car do you drive?" "A blue Ford". What dimensions are they and what voltage gives the 300W maximum? Where is the tec from, how many junctions are involved, have you gone for epoxy potted? Will it be soldered to the waterblock? What current are you intending to have each one draw?
I hope you are aware that a 300W Qmax peltier does not move 300W of heat. It'll try to move 300W through a zero degree temperature difference. Thermal resistance gets in the way of that even if a 300W-for-no-gain device wasn't much of a problem by itself. To have any hope of reasonable efficiency while maintaining at least 15 degrees between the hot and cold loops tends to require more than two peltiers.
The design I pick up and alter a bit every couple of months is looking at using twelve 40mm, nominally 15V peltiers running at 6V from an atx supply. I'm getting hung up on the heat exchanger design which you've outsourced to ultrasonic.
That irritation over with, I've just noticed:

Assuming these are different to the 24V meanwell, what do you mean? Modern ATX power supplies output nearly everything on 12V, and 30A at 12V is 360W. Not 1200W. If you're using "1200W" power supplies which can only output 30A, the solution isn't sticking several of them together, it's throwing them in the bin immediately. My paltry little 800W model is rated for 64A at 12V.

if people take the time to read properly and not use this as an excuse to try to bash someone for doing a build ,then this would make it a more comfortable log.
as you saw in the list the 2 other psu's ,ie.the 1200 wat ones ,have nothing to do with the tec's or they would have been listed within the part :
"T E C CPU Cooling
Custom Hand Made Block by Ultrasonic2
Mean Well HRPG 600 24V PSU
2 x 300Qmax TEC's
Controller = Tbalancer bigNG"
as you can see here i have an adequate psu for the tec's :Mean Well HRPG 600 24V PSU
this is the model number of it and well if you wanted to know more about it then just google the model number ,,,,
http://lmgtfy.com/?q=Mean+Well+HRPG+600+24V+PSU
,also i had also mentioned in the post that my blocks were being made by Ultrasonic ,who makes and provides the blocks installed,so if i had a car that was made by ford ,but kitted out by a well known name then you would at least know that it was going to be a good job ...To my knowledge ,Ultrasonic doesnt make crap or provide crap quality with his blocks ,....
Please can we just refrain form trying to bash the builder ,we do these things because this is what we enjoy ,if i was going to produce a low quality tec build ,then i would have used sommet out of a car fridge ,since the Tec build is costing me over 500.00 so far just for the TEC side of things,then this is not a cheap crappy build that has been entered into without thought.
I appreciate your input ,tho it does border on the build basher side of things .
I started posting this in here to share my build so far ,the temps i was getting ,the cpu oc so far on air and water ,to also try to better the system and scores by moving to TEC'S which not everyone endeavors to move to ,due to the complications with waterproofing everything properly and also configuring everything so that i gaet the best out of what i have built .
As to the "what current do you intend to draw side of things " your kinda putting the cart before the horse here as the thing isnt even built yet so i cannot do this and provide the information untill it is complete ,then i can actually configure it to what specs i so choose .
...I have stated that i would be providing a build log ,when everything is here ,and ready to do ,,,i did say all the parts are already bought ,but i did also say they were not all here yet ,so give a guy a break .
Again ,just to be polite ,i do appreciate all the useful comments .

this is going to be a good thread...looking forward to seeing your build take shape.... people always want to focus on the negitive things it seems and bash others for being brave or adventurous....i have though about using tecs in the past but it never came to anything so hats of to you for doing it.....jonj678 seems to know his stuff about them and im sure he will keep you right as the build takes shape....

i dont doubt that he does and am all for asking for help and taking it too .When everything is here and i am flying along with it or if i finish it and it doesnt work ,which i very very much doubt ,then that will be time for the rubbishing and that will be fair game ,but not when someone is setting out on it ,having already sought advise from a few of the experts that have already done their own builds and with whom i talk to every day .
Asi go along with things i am logging pictures and such and writing all details about what i am doing ,,,When it comes time to post the actual build then all details as it goes along ,will go up too .
If i wasnt as strong minded as i am ,some of the posts that i have "felt " in here already would have put me off and the bitching that was going on with the negativity would have also put me off ,My thoughts are ,if some one is going to do something new ,then support them and offer help ,not rubbish the idea and then proceed to try to rubbish the person too ...
I will complete this ,i will produce a good thing here ,i will log it and if others dont want to share the love ,that modders and such feel ,then dont bother commenting .
To those who have shown a brilliant attitude towards this build ,i thank and praise you all .

I capitalise the letter 'I' when it is by itself. I also understand that spaces come after punctuation and not before.
These things make me assume that you wouldn't understand how to run a rig as complicated as the one you are describing.
Perhaps I'm jumping to conclusions, I am however very interested in the results of this project, and wish you the best of luck.

I can read. I did read. I suspect you didn't.
That's a link to Google about the power supply. I'm asking about the peltiers, as if you use inappropriate ones the build isn't going to work at all, and you'll be £500 down.
If you're using 1200W ATX power supplies which are rated for 30A at 12V, they're rubbish.
I am staggered that you think wading in and hoping for the best makes more sense than doing any very basic calculations beforehand. How much current they draw under different circumstances is critical for choosing an appropriate controller, power supply, and hot side cooling loop. What temperature you will reach is critical for determining insulation and whether this is actually worth doing.
Best of luck.

get a grip...this isnt a spelling competition
the guys telling us what he plans to do with his project...
not to be talked down to by you
it would appear that he has a friend who has these tecs running as stated in the OP.... this is most likely why hes using them because in his eyes they are tried and tested..... jonj678 your posts come across like your atacking the man instead of maybe just giving him some advise...you obviously know your tecs so without getting personnal just stear the guy in the right direction

As for thinking i have waded in ,you are very mistaken ,i just do not need to explain myself to someone who has been negative from the start ,you may be good at what you do in your time ,but how dare you try to assume you know the type of person i am or how i go about doing things as i take everything that i do very seriously.
As for the controller ,i know it is appropriate ,because i have researched it ,i know the psu is also appropriate ,this was also checked by myself and also had advice given by other friends <---,note the word here ,people who know me personally and who i count as a friend and appreciate their advice and train of thought and who are always willing to offer their help and advise ,without judgement or reservation.
The water loop is more than appropriate and adequate for the job ,,,how do i know this ,because i have checked this all out ,i have used the tec calc ,i have researched the parts needed and the process so, when the parts come ,i will start and do the build log too .
As for the comments here,if you dont want to be part of this in a helpful way then please dont bother.
I know the quality of my work
I know the effort i put into things
The results i have had on projects before
But most of all i have never tried to rubbish anyone ,either publicly or otherwise.
If you feel that this is all you want to do then please continue,if thats what floats your boat .

It seems futile ,to try to deliver a build log in this atmosphere here ,i think it would be more beneficial if i just decided to keep things to myself and then just post a *****ing picture of completed build and temps as a picture will show the proof.
For those of you who were welcoming and critical in a non ignorant fashion then thank you for your time . Those of you who were, i would not even waste my water if a fire broke out in.

these are great...i had one a few years back cooling my loop.....i had it wired through a 12v relay so that it came on with the pc and it could take it down in temps as far as i wanted it to go before hitting dew point..... via aqua do one also which is a nicer unit the haliea one can be quite noisy when its at your feet
It is unusual for someone who has thoroughly researched the design to refuse to answer very short questions about it. I would like to know which peltiers you are using, as they may be a viable alternative to the ones I'm looking at.
So, you don't want any advise on the design. You don't want to tell people any details of the design. What then was the intention behind this thread?
edit:
Let me guess, you're dyslexic and too thick to find the spell checker? As otherwise, the standard of English with which you are posting strongly implies that you do not take everything very seriously.

when i said at the start ,,i would be posting a build log ,when i start the build ,then tell me ,,,what does that tell you ? .Any and all information will be posted then .
As for you stating about the psu ,you did not take the time to read ,did i say i was using the 2 x 1200 wat ones for the tec ,,,nope ...thats why i gave you the link to the mean well psu as this is the one i am using ,why else would i list IT in the TEC parts at the bottom of the system specs .
I do not require any help on the design as i have already this worked out ,,,even though this may seem hard for you to undestand as you seem to think you can presume to make assumptions about the type of person i am .
