I felt a bit concerned upon noticing my Corsair AIO coolant temperature at 43°C. Could anyone share the ideal range for full load operation or the maximum safe level? It appears the temperature rises steadily until the load is stopped. Thanks in advance for your advice.

Varies with your processor and maximum temperature rating. 43C remains acceptable. Typically, most all-in-one units reach their peak performance at around 60°C coolant levels.

i dont think its bad, think of liquid as a heat absorbent material, so cpu is puting all the heat into the liquid and it goes arround in the loop, the radiator is what takes the heat away from the liquid to the enviroment, so consider increasing fan speed and checking for dust or obstacles that could decrease efficiency of cooling ability. if the radiator is small and cpu is using a lot of power (intel 12,13th gen) then maybe it gets owerwelmed with the heat that cpu is putting to the system. also i wanna add that liquid coolers isnt as efficient as air coolers with long sustained heat vs size, it needs bigger radiator for liquid cooler to be as effective as air coolers long term. but liquid coolers are very good at short bursts because liquid can absorb a lot of heat. the hotter the liquid the better radiator efficiency because of temperature difference.
