> TPU chips are hooked up in series in the loop, which naturally means some chips will get hotter liquid that has already passed other chips in the loop. Cooling capacity is budgeted based on the requirements of the last chip in each loop.
Of course, it's worth noting that if you've got four chips, each putting out 250W of power, and a pump pushing 1 litres of water per minute through them, water at the outlet must be 14°C hotter than water at the inlet, because of the specific heat capacity of water. That's true whether the water flows through the chips in series, or in parallel.
