ASUS NUC 15 Pro — High-Performance Fanless PC with 15th Gen Intel® Power

Experience next-level computing performance and total silence with the latest ASUS NUC 15 Pro, powered by the 15th Gen Intel® Core™ Ultra 7 255H processor. This compact, totally fanless PC is engineered for power users who demand top-tier performance, robust connectivity, and absolute reliability — all without a single moving part.

Fanless Cooling with Advanced Thermal Engineering

  • Custom-designed aluminium case uses heat pipe technology to silently transfer heat from the CPU to external cooling fins.
  • Aluminium heat blocks cool both the PCIe 5.0 SSD and DDR5 memory to prevent thermal throttling.
  • Supports up to 4x 4K displays via dual Thunderbolt 4 (Type-C) and integrated HDMI outputs.
  • Silent, fanless design ensures efficient, maintenance-free operation even under full load.
  • 24/7 reliability through rigorous burn-in and performance testing.

AI-Ready with Triple Engine Power

  • Delivers up to 96 TOPS of AI compute via three AI engines, including a Neural Processing Unit (NPU).
  • 16-core hybrid architecture: 6 Performance cores, 8 Efficient cores, 2 Low Power Efficient cores.
  • Intel® Arc™ Graphics provides 3.7× higher 3D performance than the i7-14700T in our TX-Series.
  • Ideal for content creation, edge AI, and demanding multitasking environments.

Connectivity & Expandability

  • Wi-Fi 7 and Bluetooth 5.4 for next-gen wireless connectivity.
  • Dual Thunderbolt 4 ports for ultra-fast data and video transfer.
  • Supports an additional 2.5" SSD/HDD, user-accessible via the baseplate.

Tailored for Performance, Built for Silence

Each system features custom aluminium cooling components designed specifically and unique to our builds, ensuring high thermal efficiency without fans or ventilation holes — perfect for quiet or dusty environments. 

Ready to Use, Right Out of the Box

Your PC arrives fully set up and ready to go. We can pre-install either Ubuntu or Windows based on your selection, so there's no setup hassle — just plug in and power up.

If you choose Windows, we go a step further:

  • The operating system is pre-installed on the internal SSD with all drivers and updates included
  • We include a USB recovery stick to help you easily repair or reinstall Windows if needed
  • You’ll also receive the official Windows DVD and a genuine licence key sticker

Note: Monitor, keyboard, and mouse are not included. If you need help choosing the right accessories or would like to add them to your order, just get in touch — we're happy to help!
