toolmaker_03 :
ok so I have decided on the final build design for my TEC setup. I will have 6 CPU blocks in total each set of two will be bolted together with the TEC in between them. the Hot side CPU blocks are all metal blocks. both the hot side and the cold side will be a 3-way parallel configuration. I will have 3 400mm reservoirs linked in parallel as a cold bank for the cold loop. I hope that this makes since, if not I can try to answer specific questions. I have already tried a few different setups with a small loop design and came to the conclusion that this is the most efficient design that is capable of cooling my loop. the only difficult part will be figuring out at what voltage the TEC's will need to be at, for both the idol temps, and load temps. I am hoping that it will be as simple as having one TEC on at idol and all three TEC's on at load but we will see.
Seeing as how I have been running TEC chilled water cooling now with my present setup in operation now over 13 solid months, I suggest you review the
exploring below ambient water cooling thread, from the point that the peltier cooling was first introduced to the end of the thread.
Which all led to
This Thread of guaranteed 100% successful TEC chilled water cooling, so hopefully you'll end up with successful cooling as well.
I would love to see you put together a fantastic system so use what I discovered that worked and did not work, because if it did not work for me it won't work for you either and you will loose a lot of time and money rediscovering what I've already proven.
No one here has experimented with TEC chilled water cooling as I have, so take what I have learned the hard way and use it for your benefit and don't make the same mistakes because they can be discouraging enough to cause you serious setbacks!
Standard CPU water blocks whether for hot or cold have to be flow modified, or they won't work, they are designed to pinpoint to the CPU die area and for cold or heat transfer the entire base must be accessed and that's a fact!
Reservoir wise it's best to just build one from scratch as I did, because it has to be insulated so looks won't make a lot of difference, and the water volume is inadequate, for 3 400mm reservoirs, you need enough volume for cold chilled water storage there is no getting around that.
These things are covered in the threads if you take the time to read over them, they were put there to help others design their own or duplicate what's already a proven cooling solution.
Sometimes the peltiers just flat out defy logic, and what seems feasible in the mind thought process, sometimes is the complete opposite when it comes to peltier chilled water cooling, as I think you've already discovered some of your ideas did not work already?
Good Luck! Ryan
