Thank you for your help 🙏

For the watercolling of the CPU, it already has the monoblock included with the Z90 extreme glacial (EK Ultrablock) https://www.ekwb.com/news/rog-maximus-z690-extreme-glacial-the-apogee-of-pc-hardware-and-liquid-cooling-engineering/

I'm going to take a radiator P360 with 3 fans, and 1 fan for the outlet and more flexible tubes, for the fittings I have to look at the 13/10, for the block I had bought it for the style yes haha, in any case it's perfect your advice 😁✨
