I bet it's a device which stops the water splashing back and hitting your arse when you take a dump
GPU AIO water cooler.
Obviously being related to the God of the sea, its either a water cooled pc, or gfx card
Yes it is related, but it has nothing to do with watercooling or water in general, just to throw a twist to it.
@Gibbo.
I was going to guess AIO Water cooler. However, its probably not water
Because of its(Neptunes) great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching 55 K (−218 °C)
Neptune's atmosphere is 80% hydrogen and 19% helium
So maybe its a more advanced "Cooling Device" rather than a liquid coolant(H2O) it maybe is more like a refrigerant . Heat disipation pipes rather than a radiator
I like your thinking, would be quite a feat. A new category on OcUK?
