i7 Water cooling system

[Jonathan]

Have you got the parts anodised, i have just started anodising my self with some great results.

I have anodised several parts myself before with good results, however this sadly is not one of them.

This is:

i think you might have sealing issue with the o ring groove due to surface finish.

I chose the correct sizes for the O-ring slots to ensure it seals properly. I will confirm this by submerging it in water and pressurising it with compressed air. If I see bubbles then either there's a problem or I'm using a much higher than operating pressure.

i would avoid nickel plating the copper as it will affect the thermal transfer.

While this is true, the effect is rendered neglegible by the several micrometre thickness of the plating. This is widely accepted as the best solution to galvanic corrosion, confirmed by nickel plating throughout the majority of high ended water coolign components.
