Silent mid-tower for rear-connector builds

The Phanteks XT Pro Silent is a mid-tower chassis built for quiet operation. Solid steel and ABS panels on the front, left and right sides are lined with sound-dampening foam. It accepts ATX, micro-ATX, mini-ITX and E-ATX boards up to 280 mm wide, including the latest rear-side connector mainboards. Three M25-120 fans come pre-installed at the bottom.

Thermals, noise and power draw in normal use

The closed panels and foam lining keep system noise low while the three included 120 mm fans supply baseline airflow. Up to seven 120 mm or three 140 mm fan locations are available across the mid-plate, rear and top for additional intake or exhaust. A 360 mm radiator fits in the top without clearance restrictions, and the rear supports a 120 mm radiator.

GPU clearance decides the fit

The case accommodates graphics cards up to 415 mm long, covering current flagship models. CPU cooler height is limited to 184 mm, and the power supply bay accepts units up to 270 mm deep. Front I/O provides two audio jacks, a USB 3.0 port and a USB 3.2 Gen 2 Type-E connector. Two 3.5-inch and five 2.5-inch internal drive bays handle storage needs.

Questions about this item

How do I mount a rear-side connector motherboard and what step is often missed?

Align the board with the rear-side cut-out and secure it using the standard ATX standoffs; the step often missed is removing the traditional I/O shield since the board has no rear ports.

What maintenance will the three pre-installed M25-120 fans need later?

Clean the fan blades and intake vents every few months with compressed air; the fans use standard 120 mm frames so they can be replaced individually if bearings become noisy.

What thermal limit appears first when running a 360 mm top radiator under sustained load?

The top panel supports a 360 mm radiator without restriction, so the first limit is the coolant temperature reaching equilibrium with the ambient air inside the sealed front and side panels.
