Thermal & Stability Validation (50+ Min OCCT Combined Torture Test)

This system has been thoroughly tested with a concurrent maximum stress test to guarantee bulletproof stability before sale:

• GPU Core Temp: Settles flawlessly at 70.8°C while pulling a massive 388W under full load.

• GPU Memory Junction (VRAM): Maxes out at a frosty 86.0°C (well below the 105°C danger zone), proving the high-performance UPSIREN putty keeps the rear-mounted VRAM completely safe during long AI training or render cycles.

• GPU Hotspot Delta: 87.2°C Max* (less than a 17°C delta from the core),

• CPU Temp: Maintains a stellar average of 76.31°C under a brutal variable core cycling workload. Transient spikes safely peak around 87°C (well below AMD's 95°C TjMax ceiling) and immediately drop back down, proving optimal mounting pressure and thermal transfer.

• VRM Temps: Motherboard VRMs rest between an incredibly cool 41°C – 45°C, showing excellent internal case ambient airflow.

• Stability: 100% stable, zero errors detected, zero thermal throttling.

*Note on Acoustics: Due to the high-airflow static pressure engineering of the unique SUP-01 layout (pulling fresh air directly through the side mesh across the radiator to blow on the back of the motherboard chamber), the intake fans will naturally become audible under full artificial multi-component torture loads.

This system will ship fully assembled and ready to plug-and-play. Has both a HDMI cable pre-routed and display port cable pre-routed. All spare cables and ring will be shipped with PC. Feel free to message me with any questions and verification of performance if needed.
