Im still rocking on a old 775 era gigabyte galaxy 2 cpu block modded to fit 1150 i54670k. I dont know why but the pump that came in the kit refuses to die, must be getting on for +10 years now and i still use the pc everyday. I rarely flush out the water and clean everything
My Swiftech MCP-655 has been going strong for 6.5 years at this point with no signs of degradation or additional noise.
Raystorm CPU block 1 month shy of 4 years. My previous Swiftech block was just fine at 2.5 years, but I wanted the Raystorm due to LED lighting...sold the block to someone here and is still kicking as far as I know.
XSPC EX240 radiators as old as the Raystorm block...no issues whatsoever. Previous radiator(s) were sold to people here in good working order.
Biggest problem I have had is with Acrylic reservoir that holds the pump. First XSPC dual bay res lasted about 3.5 years and was all cracked/spider webbed...never leaked though. I bought another of the same and it is doing just fine presently.
Since I started with custom loops I have never done a routine drain/fill for maintenance purposes. It only gets done when hardware changes unless there is an issue...only major problem I had once was cheap barbs that flaked and clogged up CPU block. Other than that, cleaning all the parts prior to installation with 91% alcohol and rinsing with distilled has worked very well for me. Proper prep/cleaning combined with Biocide and silver kill coil/plug has been flawless for me. Longest time between a drain/fill was around 2.5-3 years with only minimal distilled water top-offs. I've never used dyes so I can't comment on that situation...colored tubing is the safer bet IMO.
If you keep an eye on operating temperatures, then you will know if/when something goes wrong...if it's still chugging along, then I wouldn't worry too much about it. If it ain't broke, don't fix it.
