Questions about this item
How often should the Gelid GC Extreme thermal paste on the CPU and GPU be reapplied?
The Gelid GC Extreme thermal interface material is applied during the build process and is designed to last the usable life of the laptop; routine replacement is not required.
Which component hits its thermal limit first during extended all-core workloads on the Core Ultra 9 285HX?
The 24-core processor reaches its thermal threshold before the RTX 5090 GPU under sustained heavy loads, triggering clock-speed reduction to manage heat.
What are the fan noise levels and surface temperatures when the RTX 5090 runs at full load all day?
Under continuous maximum load the cooling system moves significant air volume, producing audible fan noise, while keyboard-deck temperatures rise noticeably above idle levels.
