Liquid cooling questions

[The Law]

Hello,I have decided to go with an all in one liquid cooling solution for my AMD FX-8350.
I just have some simple questions before I actually buy it because I have some doubts.
1.How often do water coolers leak and how can I prevent leaking?
2.How long do water coolers last?Are they durable or they break after a year or less?
3.Are the temperatures significally lower than with air cpu coolers?
I want liquid cooling because it looks so much better and doesn't block ram slots and takes less space and I've seen better results over air coolers.

1. If you buy from a good brand, leaks aren't very common at all. Most give warranties for 3+ years.
2. AIO water coolers are supposed to last 3+ years, and are pretty durable. You should definitely get more than a single year out of it.
3. Not really. For cheaper, you can get a Noctua D14 which is much quieter, and cools almost as well as the H100i.

If aesthetics is very important, there is nothing wrong with going with something like an H100i or an Eisburg 240L (or however it's spelled lol).
