Questions about this item

Will the 360 mm liquid cooler keep the 24-core Core Ultra 9 285K at 5.70 GHz under sustained load?

The 360 mm Quiet Edition AIO is designed for the 285K and its 36 MB L3 cache, but sustained 5.70 GHz depends on case airflow and ambient temperature.

How loud are the 140 mm case fans at 1500 rpm during all-day operation?

Each front and rear 140 mm fan is rated at 30 dBA at 1500 rpm; the PSU also uses a quiet 140 mm fan for low overall noise.

Does the motherboard need a separate Wi-Fi antenna or is it included with the Z890 TUF board?

The TUF GAMING Z890-PLUS WiFi7 board includes integrated Wi-Fi 7 2x2 and Bluetooth 5.4 antennas in the rear I/O panel.
