Questions about this item

What case clearance does the 360mm AIO liquid cooler require?

The 360mm AIO liquid cooler needs a case with a 360mm radiator mounting area and enough clearance for the radiator, fans, and tubing.

How is the 64GB DDR5 6000 RGB memory installed, and what step is often missed?

The 64GB DDR5 6000 RGB modules are pre-installed in the motherboard slots; the step often missed is enabling the XMP or EXPO profile in the BIOS to run at the rated 6000 speed.

When will the 1200W Gold ATX 3.0 power supply need replacement?

A 1200W Gold ATX 3.0 unit typically lasts several years; replacement is needed if fan noise increases, voltages drift, or the system becomes unstable under heavy load.
