so... logic doesnt work on your mod my friend... i have an 11x11 reactor with a single core in the middle, surounded by liquid ender, logically, the liquid ender would transfer the heat from the core to the case, thereby cooling the core and heating the case. this doesnt appear to be the case. in fact it doesnt appear to make any difference from my 5x5 reactor. even though the amount of cooling liquid is multiple times the amount of previously.

if you are really against this system why not make heat sink blocks that can be put inside the reactor to transfer the heat?

just seems like the mod doesnt work how i imagined it would.

Only the blocks immediately surrounding a fuel rod matter for heat transfer. Larger pools are useful for dealing with radiation, but are irrelevant for heat.
