If you water cool those tecs, that would be sweet. use one quad for the tecs. tecs straight to CPU. 2 quads for a GPUs... If you do add a quad for the cool side of the TEC loop, try it with no fans then low speed fans first
There is always the option of insane TEC cooling as well. Say 200w?
It is $45, but bear in mind it needs a power supply/regulator those uh, 24v maxwells (?) that people started using for GPUs a few years back

another consideration, getting some 15V units and just running them at 12v (they dont sell 12v)
Costs a bit more, on tec side but you could actually run them off a PSU... 2x15v 130W TECS at 12v = probably close to 200W cooling without needing separate PSU...
Yeah I know it wont look as cool as the Boreas either.
