This conceptual work proposes a speculative engineering architecture of a three-dimensional computing cluster in the form of a regular icosahedron, leveraging the synergy of advanced two-dimensional materials and topological semimetals. As physical limitations of traditional silicon electronics scaling approach, this paper explores an alternative path combining molybdenum disulfide (MoS₂) for transistor channels, niobium phosphide (NbP) for interconnects, and an embedded microfluidic cooling system based on vertically aligned carbon nanotube (VACNT) arrays integrated into a liquid crystal polymer (LCP) composite matrix. MoS₂ is proposed as the active semiconductor layer, offering atomic thickness (0.65 nm), high carrier mobility (~39.7 cm²/(V·s)), and excellent short-channel effect control for sub-1nm scaling. NbP demonstrates anomalous reduction in electrical resistivity (~34 μΩ·cm at 1.5 nm thickness) when film thickness decreases below 5 nm, overcoming the "copper barrier" that limits traditional interconnects. The embedded microfluidic cooling system, utilizing VACNT/LCP composite channel walls with axial thermal conductivity exceeding 3000 W/(m·K), is designed to dissipate heat fluxes over 1000 W/cm². Hexagonal boron nitride (h-BN) serves as both electrical insulator and thermal spreader (thermal conductivity ~420 W/(m·K)). A step-by-step technological route is proposed, including VACNT growth, 2D heterostructure transfer, NbP contact formation, and 3D assembly using rigid-flex PCB technology. Comparative analysis suggests that the proposed architecture could achieve clock frequencies of 15-30 GHz and performance 5-10 times exceeding current flagship silicon processors, while operating at technological nodes of 2 nm and below. This work is presented as a speculative engineering concept based on current experimental achievements in materials science, aiming to stimulate interdisciplinary research at the intersection of condensed matter physics, materials science, and computer engineering.
