Help a WC noob, why has my fluid turned yellowish/orange.

Ok, the orange color is a dye you used? If not my guess it's a reaction compound between the aluminium rust that had caused the color, and for the sticky part coming from the blocks, it have to be the alumina. That can't be cleaned property since it's already rotting, the only solution is to change a new one or be professional refabricated. I never RMA a water-block before, but I think it's under warranty. Next time avoide aluminium made blocks, especially the non-painted ones.

The Dye I used after the first flush was D-Tek Fluid F/X alien green..the water did not go green let me tell ya. It ended up orange.

See pic. Pure PC + dye should equal glass but I got the Orange at the end LOL.
