MI50 GPU Direct-Die CNC Waterblock
"Solid engineering judgment. Handled tight micron tolerances for the O-ring compression and microfin channels ready for machine tooling."
Precision mechanical CAD and custom liquid cooling channel design for CNC milling
Engineered a high-tolerance custom liquid cooling block tailored for AMD Instinct MI50 enterprise accelerator boards.
Enterprise server GPU cards rely on loud, passive high-CFM server rack airflow fans that quickly thermal-throttle when installed inside standard workstation cases. The client required a precision copper and acrylic waterblock designed specifically for sub-millimeter CNC machine fabrication.
Had never engineered custom liquid cooling channels with O-ring groove compression tolerances or CNC manufacturing constraints. Researched fluid dynamics channels, microfin clearance tolerances, thread pitch specs (G1/4"), and CNC endmill bit path limits.
Modeled precise micron-accurate PCB standoff clearances, engineered a 0.4mm microchannel cooling fin array directly over the GPU die, calculated O-ring seal grooves with exact 25% compression ratios, and exported certified STEP files ready for CNC machine tooling.
Delivered verified CAD engineering models and technical dimension sheets conforming to CNC fabrication standards with complete thermal assembly clearance.
