What Happens if you Water Cool an Air Cooler? delivers a hands on exploration of unconventional PC cooling by submerging and circulating water around an air cooler style heat sink. The video centers on a purpose built passive cooling motherboard from ANC tech, designed for minimal active cooling and dust resistance in workshop environments. Linus and the team walk through the design choices, showing how the CPU socket placement and the unique heat sink affect heat transfer and system viability. They experiment with the hardware setup, nodding to the challenges of fitting a large passive cooler into standard cases and addressing compatibility quirks. The host group jokes about the oddities of assembling this unusual rig, while highlighting the potential of water assisted cooling in scenarios where fans are undesirable or impractical. By testing under load with OCCT, they reveal how temperature behaves with submersion and additional components, drawing conclusions about the practicality and limitations of this radical approach. The segment concludes with reflections on how to improve real world daily use and teases a future product oriented toward gaming and more robust cooling options, alongside a sponsored segment about FlexiSpot desks.

Questions answered

What is unique about the ANC tech rev Q2 70 motherboard as used in this experiment?
The motherboard is designed for passive cooling with CPU socket on the opposite side, enabling a novel cooling approach and modular, dust resistant design for industrial environments.
Why do the hosts attempt water cooling for an air cooler instead of a traditional liquid cooling loop?
They want to explore whether submerging parts and circulating water around a heat sink can improve cooling efficiency when conventional active cooling is limited by space, dust, and mounting options.
What challenge did the team face when mounting the large heatsink in a standard case?
The heatsink and the topology prevented easy installation; many cases interfered with the top of the heat pipes, requiring consideration of modifications or unconventional mounting approaches.
What was the notable outcome of their OCCT stress test with the submerged setup?
The system demonstrated improved thermal behavior under load, with temperatures dropping significantly once water cooling effects took hold, illustrating both potential and limitations of this approach.
