PC Water Cooling Escalation: Radiator Swap, Coolant Issues, and Liquid Metal

Unexpected Radiator Upgrade

• 💡 The initial plan to swap radiators for thicker ones from Singularity Computer quickly became complicated due to clearance issues with fans and tubing.
• ⚠️ The new, thicker radiators (60mm) were found to interfere with RAM and motherboard components, forcing a re-evaluation of the build.

Coolant Degradation and Maintenance

• 🔬 A significant issue was discovered with the Corsair coolant, showing signs of degradation and build-up within the CPU and GPU water blocks.
• ⚠️ This build-up, potentially exacerbated by added blue dye and reused components from previous builds, led to a noticeable decrease in pump flow rate.
• 🛠️ The solution involved disassembling and cleaning the water blocks, with a focus on the Dar-Bower block's easily serviceable center plate design.

Liquid Metal Application and Testing

• 🚀 Liquid metal was applied to the GPU die for maximum cooling potential, using a "moat" created with foam and clear nail polish to prevent spills.
• 🧪 Testing on a water cooling station confirmed that the liquid metal was effective, keeping GPU temperatures significantly lower than before.
• 📈 The system showed improved coolant temperature stability, with viscosity thinning as it warmed, leading to better flow.

12V2x6 Connector Issues

• ⚠️ A critical problem arose with the 12V2x6 power connector on a high-end GPU, where a pin became bent and misaligned.
• 🔧 This issue, not expected on expensive hardware, required careful manipulation to push the pin back into place, highlighting the fragility of these connectors.
• 🔍 The importance of proper alignment and avoiding excessive force when connecting power cables was emphasized.

System Reconfiguration and Final Results

• 🧩 The build was reconfigured, opting to bypass the distro plate's intended flow path for a cleaner aesthetic and better tube routing.
• ✅ Despite the challenges, the radiator swap and maintenance were deemed a success, with improved thermal performance and resolved coolant issues.
• 💬 The presenter acknowledges the complexity and potential frustrations of water cooling but reaffirms it as a rewarding enthusiast pursuit.
