Question Question about AIO water cooling

Considering a build with a 3900X. My previous builds always were with Noctua CPU fans, so no experience with water cooling. I would normally go with the NH-D15 for this build.

How does typical AIO water cooling compare with respect to reliability, noise and performance? For reliability, I'm talking in-service life of 8-10 years. What is the usual point of failure: pump, leaks? For noise, is it the pump, or the fans? Better to have 3 fans and longer rad or 2 fans and shorter? Brands/models to stay away from (reliability-wise)?

For performance, I can determine from reviews, but I don't see much on long term reliability.

Case will likely be a Fractal Design Define R6C.

Thanks
 
I highly doubt any AIO pump will last 8-10 yrs.
These are not industrial certified pumps like a liang D5 is on the custom LCS side we use which some have lastested 10yrs or more.
 
8-10 years is a lot for any mechanical part if its running 8+ hours a day. Even a lot of fans will start to fail by then.

I have never had an AIO outright fail on me (knock on wood), but been running a Corsair H100i for almost 5 years without any issues. I prefer this setup over a big fan as the CPU runs cool, its quiet, and all the hot air exits the case directly as the radiator air exits the case. And since I have a SFF case, not having hot air dump out inside it is nice.

The case you are looking at would be good to use with a radiator as those cases have pretty poor airflow because of the solid front. The small vents along the side of the front aren't nearly adequate enough.
