Questions about this item

Can the 16GB DDR5 memory or 2TB PCIe SSD be upgraded later?

The 16GB DDR5 memory and 2TB PCIe SSD are upgradeable; the supplier opens the original seal for professional upgrades and provides a 1-year warranty on upgraded RAM and SSD components.

What thermal limit appears first when the Intel Core Ultra 9 275HX runs at 5.4 GHz turbo for long sessions?

Sustained 5.4 GHz turbo on the 24-core processor will hit the cooling capacity of the 0.93-inch chassis before the CPU throttles, making thermal headroom the first practical limit.

How loud are the fans and what is the surface temperature when the RTX 5080 16GB GDDR7 runs all day?

Under continuous load the dual-fan system spins up to move heat from the RTX 5080 and 275HX; expect audible fan noise and warm keyboard deck and exhaust areas during extended gaming.
