hey thanks for following right just to start with
what is the components you will be cooling? (what cpu you have graphics card ect)
what kind of temps do you want roughly
what kinda budget do you have

I am using an i7 6700K, cooled by Corsair H110i, but looking for a way to bring the temps below ambient, maybe 8 deg C. Your work on the chiller is very good. I have an ASUS 970, and I want to cool both the GC and the CPU with good custom loop. My budget is very open, my wife is financing my playing around with computers.
I am not interested in bringing the temps below dew point, just want temps better than ambient.
The Corsair shows 26 deg C at middle, haven't begun to stress it yet. But I think it will go to 80 C, and overclocking would be much easier at the lower temps.

well you want a controlled loop then so with a 6700k overclocked will be around 150w? or so then a 970 i have no idea.. but id say you will need quite a big chiller to cool the cpu and gpu... this would need a couple of bigger peltiers undervolted so some 62mm tecs at arounf 7-8volt would be ideal but then you need to cool them.. aswell as the cpu and gpu so you will have to have a really big case or a radiator rack

on my chiller my cpu was around 200watt and i was running 3 250w 12715 tecs at 10 volt i got -11*c idle but then shot up into 40-50's but think that was due to bad mount.. but it was alot better then just watercooling the same clocks would go to 99*c and shut down the pc in bout 5 mins but it use to put out alot of heat and use alot of power

so with your set up i would get a few 360 rads to even start and a couple of powerfull pumps but its trying to find the waterblocks unless you can get some made?

or you can use alot of smaller peltiers and alot more waterblocks but can buy them online easy and just make a couple of mounts to hold them together but you will have the problem i did as i desided to use perspex to hold them together to help the thermals of things and help the insulation abit better.. but it cracked due to the pressure i needed and the heat change from hot to cold back to hot

at the moment i was thinking about adding an extra 250w peltier for the cpu and was going to use 3 156w peltiers just to chill the graphics card but it wont cool it on its own but i am having alot of issues at the moment with some health problems family problems and broke my pc so need to get that all fixed again to start saving up and building a new chiller and new power supplys

For the blue alloy waterblocks for peltiers, 40MM and X MM long.
They actually have spcial mouting mechnisim designed just for them.
I know cause they sell them on the chinese website

Can't get enough pressure out of them cheap little clamps why I chose 20mm thick Perspex and even that wasn't enough

Have you tried them though?

They sell ones that use stainless steel, even if its just steel.
Its more than overkill for moutning the block.
The alloy will bend and break before the metal piece with bolts and nuts even get damaged

Thinn galvonised metal sheets counstruted as a shelf to hold tools.
It can hold up 200KG

I noticed that your topic is the strength of the clamps used to hold the TEC's I am planning on using 1/16" thick by 1/2" aluminum angle for the framing I am making for my acetal CPU water blocks, this should make them a little stronger.
I can get thicker aluminum angle to make the frames out of for the CPU blocks, what do you think?
or what would you do to make the blocks stronger?

I've seen people use them using them brackets to hold them to a gpu and they bend and I know a gpu dosnt take a lot to bed so that shows how weak they are for holding pressure of two blocks together..

And yea a think steal shelf will hold a can engine.. Been there done that but your forgetting the structure it has folded and seamed edges to make it not flex or twist if it was a normal thin flat bit of steel it would bend under its own weight with our no support exept in the corners to life it up enough to let it bend....

Aluminium box tube is good but even the stock cpu brackets take a lot you'll break a bolt or nut before you need to make that any stronger lol

Also got a pic of inside the block and the base size? As inside needs to be the same size as the tec so you won't get hot spots around the edge and warm up the cold side o

well I can take one apart but the inside of the block is a square

does this help?
