Questions about this item

Will the 360mm liquid cooler need coolant replacement or pump service?

The 360mm liquid cooler is a sealed unit; no coolant replacement is required. Pump longevity matches typical AIO lifespans of several years under normal use.

Which component hits its thermal limit first during sustained all-core workloads?

The Ryzen 9 9900X 12-core CPU will reach its thermal ceiling before the RTX 5090 under continuous heavy compute loads.

How much noise and heat does the 1200W supply produce when the system runs all day?

The 1200W PSU fan spins up only under high load; at typical gaming draw it stays quiet and exhausts modest heat through the rear mesh.
