Finishing My Dual 3090TI Custom Loop Water Cooling Build

In this thrilling conclusion to our dual 3090Ti AI PC water cooling upgrade, we complete the custom loop that will supercharge our 70B local LLM powerhouse. Building on the foundation laid in Part 1, this video takes you through the final, intricate steps of creating a high-performance cooling system.
Watch as we tackle the challenges of hard tube bending, bringing our cooling dreams to life. We'll guide you through the process of plumbing the entire system, ensuring optimal flow for maximum cooling efficiency. In a creative twist, we design and 3D print a custom spiral mandrel using Fusion 360 - though its final use may surprise you!
The moment of truth arrives as we fill the loop, giving you a first look at our fully assembled liquid cooling masterpiece. To put our hard work to the test, we fire up Furmark for a benchmark that pushes our dual 3090Ti setup to its limits, revealing the true potential of our custom cooling solution.
Whether you're an AI enthusiast, a PC building aficionado, or simply curious about the depths of custom water cooling, this video offers invaluable insights into the world of high-performance computing. From the triumphs to the challenges, we share it all, including why this might be our first and last custom loop build!

nicely done! :) dig the end result and like the way the CPU cooler fits in with the overall aesthetic

Thanks very much! I was unsure of how the "hybrid" setup would work with the air/water cooling but I am very happy with how the silver of the cpu cooler fits in.

That’s cool man! It’s one those things you enjoy look at from a distance lol

[@OminousIndustries]

Thanks very much! Yes it is good to look at and hopefully not have to work on again LOL

Beautiful loop! I’ve always wanted to do this but it seems like too much work. I think I will stick to an AIO 😂

[@OminousIndustries]

Thanks very much! Yes, I massively underestimated the amount of work and expense involved. The AIO is a perfect solution hahaha
