At this point, I only recommend custom looks for water or a really good air cooler. Just do some googling about AIO cooler failure. Many get filled with gunk inside, dry ant but can not be filled. Or, can be filled but have no easy way to monitor the level like a typical custom loop.
It is your money and time, so do as you wish. I only make my points based on my experience and observations. I was pretty gung-ho for AIO in the beginning. Now, I won't touch them.
I understand your point of view. If also I had a bad experience with them, I would stay away.
But my knowledge till now around watercooling comes from custom made loops. We are talking for handpicked elements (block, radiator, pump etc) and using such a system for around 8 years through 3 different PC setups and never having any leak.
Nowadays with these sealed AIO systems all risks are simply out of the picture and in my case it looks as there are 3 scenarios:
1) stay with the current Mugen cooler, but nothing will change with my bench scores
2) Change to an aircooler. To do that I must spend around 100euro or more to get the best aircooler, but probably also the noise will increase
3) Change to watercooling. The performance will be similar to the best air cooler, but with less noise for sure and also will less money, as I have found the AF II 240 at 85 euro with shipping from Germany.
