ok, so this build just keeps getting tighter, and tighter. I guess that is a good thing, the power supplies are a lot closer together now, and I will keep playing with there positioning a little before I mount them to the table. the area inside the radiator bank will no longer be a void of space as a lot of wiring will now have to be routed through that area. the newly opened space is now ready for remodel, I have the room to add the second TEC assembly, and the reservoirs to the table top.

could you array all of your radiators in a straight line along the edge of the table, the same as the middle 2 (the ones that get water straight from the pump) move the left and right pairs so they are all in straight line along end of table, seems like it would free up a lot of space.

Also, are your fans all in pull? Depending on the fans, wouldn't it be better if they were in push?

Just more of my opinions, so ignore me if it's too late/too much work to change it now.

well, that is a cool idea for freeing up some space, but I really don't have that kind of room across that back of the table top.

yes, all of my fans are in a pull position from the radiators, I have tried them in a push position as well, before deciding on this configuration for the fans.

He is never going to get done making drastic changes like these suggestions.

IMO, Getting the better quality peltiers is great, but at least try those 3 out first before proceeding with a 2nd complete TEC assembly.

Stick with your original idea and if it doesn't pan out then change it, if you don't, you will always be wondering if it would have worked as you planned.

If you have to remove the clay to change out the peltiers, IMO you need to rethink the parallel flow arrangement you setup on the cold side of the water blocks, that would work best in series flow to remove the cold building up as fast as possible and get it to the insulated reservoirs.

I know parallel flow has worked great for you in normal computer cooling but this is different, so at least think about it.

it would be better in series on the cold side, that way the water that is circulating spends a longer period of time in the cold blocks rather than a short period of time in 3 blocks. with such a large reservoir series config would be better. Hot side can do either series or parallel.

OC, are you cooling CPU and GPU's? If tools games for an extended period of time with his 600w heatload from CPU and 2 GPU's without adequate TEC Qc his reservoir will not be able to keep enough chilled coolant buffer to handle it, so I think for his 600w heat load and a target of minus 10 to 0*c he will need 6 TEC's. But yeah I would have tested with 3 first. Just to see if it was satisfactory, and also because going from 10*c to minus 10*c won't really net much in terms of extra overclock. I was just saying if his goal is subzero with constant 600w heat load he will need 6 TEC's.

it will be just the three TEC's to start out, as it will take some time to build the second TEC assembly, the second reservoir bank, and all of the fittings for them. so, for now I will use the system as is, I am adding the radiator to the inside of the ice chest, and mounting the reservoirs to the table top right beside the ice chest. I know it keeps changing, but I have a goal for this system, and I would like to see it with this build, before I start a final build for my next system.
with the next system I will most likely use a different ice chest, or make a chill box out of aluminum.

What kind the CPU block you use for TEC assembly? is it a full cover or center concentrated block? if it is the later you might have hot spot because of the flow design. Sorry I try to search the thread but it gets so long redface.gif

it's a migicool universal CPU water block.

it's not center focused so it does a pretty good job of cooling the whole TEC.

Only the CPU, the single GPU adds too much heat to the reservoir under constant gaming load, but the CPU alone has no problem even under Intel Burn Test.

My CPU is an i7-3770K Ivy Bridge 77w TDP, it takes 2 200w peltiers (actual tested power draw) constantly running, and the 3rd 200w thermally relay controlled to maintain a 10c coolant temperature in the reservoir which is about 15c below ambient.

So raw facts wise it takes 7 times the CPUs raw TDP just to run my CPU at 5ghz 100% stable with a 10c coolant temperature, which becomes more like 6 times as at the 5ghz overclock the CPU TDP is between 90w ~ 100w.

And I am fully aware my cooling solution is not as efficient as many are, uses a lot of electricity on a yearly basis, but, being able to run a 5ghz rock solid overclock on a 3770K that has never been delidded, with all cores enabled plus hyper threading will flat out spoil the heck out of you.

I agree with your assessment of Tools 600w heat load falling way short with the 2 added GPUs, if he just runs the CPU he may reach his goal of going sub zero but that depends on his CPUs TDP.

That sir is one of the very reasons I suggested way back in this thread that he pretest what the combined peltiers could even do.

Unfortunately, Some things just have to be learned the hard way.
