"Modules with the same coolant and exhaust temperature share the same collective pool of radiators" did not fit in the thread title.
Practical application 1:
Say the craft you are building needs 73 crew and you don't feel like making a new crew module for this one craft. If you use three 25 crew modules the new crew requirement will be 77, if you use two 40 crew modules your capacity is now 80 and your craft is unnecessarily heavy, so you use a 35 and a 40. Now you need two separate sets of crew radiators even though they are probably using the same coolant and definitely have the same exhaust temperature. Currently if you manage to lose enough of one set of radiators will render the associated crew module unusable even if there were enough extra radiators in the other set to continue operating both.
Practical application 2:
Say you are trying to build a laser star to fit within a certain mass budget for a challenge on the forums, you do some back of a napkin math to figure out that the amount of mass you can invest in reactor and radiator area and it comes out to an odd number like 350Mw. Instead of building a new 350Mw reactor you decide to use three 100Mw reactors and five 10Mw reactors. (Or I guess three 100Mws and four 10Mws and the extra crew module you will need to run multiple reactors). Assuming your reactors already shared an exhaust temperature, and a coolant, it would be beneficial to you to have all of the reactors modules sharing the same pool of radiators for the same reasons as application one above. Additionally it could allow you to use fewer total larger radiators and save on crew mass requirements.
Practical application 3:
Say you are trying to build a laser battleship with 50Gw of total power. You decide that you want ten, 5Gw, sub meter aperture lasers, with turrets armored with half a meter of aramib fiber, for the purposes of dueling other lasers and swatting missiles. You also decide that you want ten, 5Gw, Multi meter aperture lasers, with turrets armored with two centimeters of nitrile rubber, for the purposes of burning through capital ship armor in a timely manner after your small lasers have stripped all of the turrets off of the enemy ship. You do not intend to power both sets of lasers at the same time, only using which ever weapon system is most relevant for the current target that you are engaging, the ship doesn't even have the power to run both sets of lasers at the same time. If the lasers do not share a common pool of radiators then you will have to have the dead weight of a complete second set of 50Gw worth of radiators to fully power each weapon system one at a time.
Practical application 4:
Say you are trying to build a general purpose carrier with a wide verity missiles and drones each individually optimized for a number of different kinds of targets. Say you are also opposed to using blast launchers, maybe you don't want explosives exposed on the hull of your ship and you don't want to spend the money armoring the blast launchers against lasers with aramib fiber or the mass armoring them against lasers with amorphous carbon. If you've built them all with the same turbo pump material and the same coolant then they should share the same safe exhaust temperature and there shouldn't be a reason to put them on separate cooling loops.
