To get this right, the designer needs to understand that the tunnel wall acts as a **seal** that cuts right across the radiator's frame. The 120\text{mm} core stays in the air, and the 35\text{mm} "tank" extension stays in the water. Here is the refined, high-detail technical brief. ## **Technical Specification: "Liberty Vault" Dual-Stage AC Tunnel** ### **1. Global Dimensions & Construction** * **Total Length:** **14 3/8 inches (365.1mm)** from face to face. * **Internal Bore:** **121mm x 121mm Square** (Constant from entry to exit). * **Wall Thickness:** **4.5mm**. * **The Joint:** Two-piece telescoping assembly with a **2-inch (50mm) overlap** at the center. ### **2. The "External Tank" Keyway (Crucial Detail)** The radiators must be mounted so the water barbs never enter the air path. * **The Cutout:** On the **Left Side** of the tunnel, the designer must model a vertical rectangular window measuring **31mm wide x 121mm tall**. * **The "Pass-Through" Logic:** When the radiator is inserted into this window, the 120\text{mm} \times 120\text{mm} finned core fills the internal bore of the tunnel. * **The External Tank:** Because the radiator has a total length of 155\text{mm}, the remaining **35\text{mm} "tank" portion** (which contains the hose barbs) will remain **protruding outside** the 3D-printed wall. * **Sealing Lip:** Inside the tunnel, on the **top, bottom, and right-side walls**, there must be a **3mm wide recessed lip**. The radiator core seats against this lip to ensure air cannot "leak" around the edges of the radiator. * **The Side Plate:** Provide a separate, bolt-on rectangular plate (31\text{mm} \times 160\text{mm}) that covers the insertion slot. This plate should have a cutout or "notch" that fits snugly around the neck of the radiator tanks to seal the tunnel while leaving the barbs accessible. ### **3. Linear Component Stack (Intake to Exhaust)** **Section A: The Intake Head** 1. **Mounting Flange:** 20\text{mm} wide lip with 5\text{mm} bolt holes. 2. **Station 1 (Radiator):** The Side-Load Keyway (Tanks protruding Left). 3. **Station 2 (Plenum):** **7mm clear air gap** (No components). 4. **Station 3 (Fan):** Internal pocket for **Noctua Fan #1** (Pulling air into the vault). 5. **The Spigot:** The 50\text{mm} male end of the telescoping joint. **Section B: The Exhaust Head** 1. **The Bell:** The 50\text{mm} female end of the telescoping joint. 2. **Station 4 (Fan):** Internal pocket for **Noctua Fan #2** (Pushing air out). 3. **Station 5 (Plenum):** **7mm clear air gap**. 4. **Station 6 (Radiator):** The Side-Load Keyway (Tanks protruding Left). 5. **Exit Nozzle:** **Full 121mm x 121mm Square opening** (No taper). 6. **Mounting Flange:** 20\text{mm} wide lip with 5\text{mm} bolt holes. ### **4. Fluid & Moisture Management** * **Drainage Slope:** The bottom floor of the tunnel must have a **2-degree pitch** tilting toward the intake end. * **Weep Holes:** A **3mm drainage hole** must be modeled at the lowest floor point of each section. * **Drip Rails:** A **2mm high "speed bump" ridge** on the floor just before each fan pocket to prevent condensation from sliding into the fan electronics. ### **Summary for the Designer:** The goal is a **completely dry air path**. By having the radiator tanks stick out of the side of the 3D print, the 800L/H pump can be plumbed in the ice water without any hoses or fittings cluttering the internal air tunnel. This design maximizes the **Static Pressure** of the Noctuas by keeping the bore perfectly square and unobstructed by plumbing.

Hey, designs like this fail when sealing and airflow aren’t engineered together, even small leaks or misalignments will kill performance. I can translate this into a precise, buildable CAD model with proper sealing lips, side-load keyways, and clean airflow path while keeping manufacturability in check. You’ll get a fully detailed assembly with clear tolerances, part breakdown, and files ready for printing and assembly without guesswork. I can share similar mechanical design work once we connect, what material are you planning to print this in (PLA, ABS, PETG, etc.) so I can account for tolerances? Let’s make this airtight and functional, Atik Murtaza
