Liquid coolers are by definition just an extra heat exchange step unless you’re venting heat into the ocean or something like a nuclear plant. Otherwise, the atmosphere is your final heat sink either way.
Unless a liquid cooling radiator is significantly larger than the air cooler that would fit directly on the CPU there’s no point whatsoever.
Of course, but when you don’t know who is a deadly foe, there’s a bit more subtlety than having to be defenseless because you aren’t certain. The risks can never be reduced to zero, and the safety of you and your team can’t be ignored.
