+1 i think he's ahad a bad WC experience.
as long as you fit a drain plug your laughing, even use some of the mayems long life coolant.
MY very first WC build about 11 years ago left a slightly sour taste in my mouth... as it leaked everywhere after running stable for a while and killed the system.
Thankfully home insurance gave me a massive upgrade under accidental damage cover.
Now though, custom watercooling is so easy, it's hard not to for the heat and noise benefits.
I already had to drain this test loop I built today once and with a y-splitter and ball valve at the bottom of the system - it's never been so easy to drain
Just to give a vague idea of improvements.
Due to one of the rads damaged in transit and the others not arriving til Monday... I only had 1x 280mm rad to build with - so to have my first attempt with hard tubing, I decided to try just that on my CPU.
With Corsair H115i (280mm rad with 2x 140mm fans)... I was seeing over 75C under full load... which also included quite a lot of noise.
And that's on an overclocked 6950X.
With a basic custom loop, but a very good quality radiator and CPU block... I am seeing 60C full aida64 load with a quiet fan profile. It's blissfully quiet, even at 100% cpu for an extended period that's beyond any real world usage scenario.
With the fans and pumps cranked up and bit but still quieter than the Corsair cooler... I'm getting 43C maximum... it's now been running Aida64 for 15 minutes and won't break the 43C mark.
This single rad could even handle a GPU in the loop with the CPU.
