hello i would like to make custom loop using CPU block with pump build in like Linus did However as i'm using Corsair iCUE 220T Case i'd like to put in something little more fancier I'm interested in blocks with display Can any of these two be salvaged for their blocks and used for custom loop?

I have Noctua NH-U9S and i was wondering if i could just to spray it with water to clean it and ease my work that way and save my tooth brush from all that dust. i worry about mainly corrosion as i don't know the metals used in this cooler
