I recently bought my first decent gaming pc, and really want to do a custom watercooling loop in it. Thinking of manufacturing my own waterblocks (partly to save money, partly because I want to) but as copper is so expensive I’m wondering if I can use aluminium instead. I know you’re not meant to mix metals, and it could enable galvanic corrosion, but I’m wondering whether annodising the aluminium would prevent this.
Does anyone have any ideas or experience with this? Would it stop the corrosion, would it still cool the system, anyone have any tips for annodising if so?
I would greatly appreciate any advice on this, I will attach a render of the my design bellow (theres a middle and top bit but you get the idea probably). Cheers
