So it's been one year into my watercooling setup. I did not notice any real temp performance drop but I did notice my fluid changed color. The purple Pastel from Mayhems faded and didn't look near as dark. I just did a mobo,cpu,ram upgrade... well side grade. Waiting on my fresh bottle of Mayhems coolant to come I decided to go ahead and drain the loop and refill with what I had in my cabinet that looked much better in color. I plan to do a full tear down and block scrub in a couple months. I did notice someting interesting.. my waterblock has a plastic clear piece in it for flow control I assume.. this piece turned almost milky white.. looks stained. I am almost curious if that is what messed up the Mayhems liquid. I will order a fresh replacement when I do the block scrub. For now it looks great and my temps are mid 60s on 2 cores and high 50's on two cores @ 4.8ghz 6700K after 2 hours of stress testing. 6700K runs as cool if not cooler than my naked 4790K did... and the 6700K is stock IHS. After owning this setup and be a frequent on silentpcreview I will never call watercooling loud. I know at idle I can get air cooling maybe a tad quieter but this system is dead silent and under load it's much more quiet than my old air cooling solution which was not cheap.
