Question AIO Block upside down

[Little one]

Hello,
I installed the arctic freezer 2 360 block upside down, I need to remount or this is OK?

Should be completely fine. Orientation in water cooling is only important when air can build up. But as the cooler block isn't the highest point in this loop I don't see anything to worry about.

Agreed per my reading it really doesn’t matter how you mount them other than front radiators perform a wee tiny bit better than top or bottom.
Wee tiny bit = 1 or 2 C
