Question AIO Cooler empty of coolant? How?

[foscooter]

Long story short.

My mother's PC was over heating, and I found that the closed loop All in One liquid CPU cooler (Corsair H60 120mm AIO Cooler) was empty of coolant.

It has been resolved, but how and where did the coolant go? I'm no chemist (obviously).

check the motherboard case for resedue
did you disassemble the cooler from the motherboard? eventually the cpu was/is wet

usually it dips just a few drops over time a year or so and vanishes

check the aio for bad fittings like

It could have leaked gradually at some point or simply permeation.
