Discolored Loop after 5 Months normal?

[Technotrade]

Im using:
11985 Alphacool Core Storm 240mm ST30 water cooling Set
14799 Alphacool Core RX 9070 XT Swift + Quicksilver with Backplate
Plus some extra fittings, Copper radiators and Tec Protect Clear 2. All Alphacool.

The loop has been assembled for just about 5 Months and was never really exposed to sunlight.

Is this normal and should I just dissasemble, clean and reassemble the whole thing or do I have an issue?

The liquid in the resservoir looks clean, but the piping is discolored and the GPU block is milky.
Cooling still works fine.

This is not normal after five months. These are deposits from components of the coolant, which should remain suspended in the liquid rather than settling. The only solution is to drain and flush the system, then refill it with fresh coolant.

Thanks for the response. Already ordered new coolant and tubing.
Can this be caused(or accelerated) by not having the loop run for 5-6 days, and/or having it run for 12-16 hours at once?
Because i have done both.

If the loop remains unused for one or two weeks, deposits can form. Normally, however, they should be minimal and gradually wash away once the coolant starts circulating again.

That said, a small amount of material can always settle and may not be flushed away, even if the loop runs continuously. There are always areas—particularly inside water blocks—where the coolant flows much more slowly than in the main flow path. In your case, however, the amount of buildup is unusually high.

On the other hand, it does not matter how long the system runs continuously. That has no effect.
