Thanks for the reply. Concerning the pastel, I've been using it for two years. Recently checked, no gunk anywhere, not even inside my previous GPU block for 1080ti. It's from EKWB.Inlet and Outlet are correct. Pastel liquid.... good luck with it. It won't take long for the radiator to become completely clogged with the colour particles of the liquid.
I'm replacing the water this week to a clear one. Was planning, just didn't have distilled water in handI would keep an eye on the liquid. We have a lot of customers who have massive problems. It doesn't matter which manufacturer the fluids come from.
