87°C18Reviewhothardware.com/reviews/alienware-area-51-2025-reviewRead 8 October 2026Exact review configuration is Core Ultra 9 285K / RTX 5090 / 64 GB dual-channel DDR5-6400 / 2 TB PCIe 4 SSD / 1500 W / 360 mm AIO. HWMonitor reports CPU peak 87 degrees C after 10 minutes of Cinebench 2024 Throttling test combined with the Cyberpunk 2077 benchmark. Lab ambient is stated approximately 20 degrees C. CPU sensor identity and precise game settings are not stated. Page 2 describes Command Center automatically selecting Performance for recognized games, but the actual global fan/power setting for this combined run is not separately documented. This is a combined CPU/GPU load peak, not a gaming-only average. No idle range, rounded noise level, approximate wall power or unspecified synthetic benchmark score is stored. The same review page 2 identifies Windows 11 Pro 24H2, fully updated through Windows Update and Alienware tools, latest BIOS and latest NVIDIA Game Ready driver at test time. Actual BIOS/driver version numbers are not stated. Baseline Windows 11 Home is a separate maker-default OS variant, not the tested OS.

63.61°C17Reviewtomshardware.com/desktops/gaming-pcs/alienware-area-51-reviewRead 8 October 2026Intel Core Ultra 9 285K / RTX 5090 / 64 GB / 2 TB PC811 / 1500 W / 360 mm AIO review configuration only. GPU temperature reported as 63.61 degrees C during 15 loops of the Metro Exodus benchmark, about half an hour. The review does not state the temperature sensor, monitoring tool, averaging basis, ambient temperature, game resolution or preset, BIOS/driver versions, or actual power/fan profile. This is a sustained gaming-loop result, not the later Ryzen 9950X3D temperature and not a combined synthetic CPU/GPU stress result. No maker-default mode is inferred. The review table states Windows 11 Pro. The baseline Windows 11 Home is the separate maker-default variant, not this temperature test OS.
