Alphacool NexXxoS ST30 360 mm X-Flow Radiator

The Alphacool NexXxoS ST30 is a full-copper radiator built for custom water-cooling loops. Every main component, including the chambers, fins and channels, is made from copper to maximise thermal transfer. It measures 360 mm in length and accepts three 120 mm fans. The X-Flow internal structure is designed to support high flow rates through the core.

Builders planning a high-flow custom loop

This radiator suits enthusiasts assembling a custom liquid-cooling circuit who want a full-copper construction and an X-Flow channel layout. It is not intended for all-in-one coolers or systems that rely on proprietary mounting brackets. Buyers who need a radiator with integrated fans or a different length should look at other models.

360 mm length with three 120 mm fan slots

The 360 mm size dictates the case clearance required and the number of fans you can mount. Verify that your chassis supports a 360 mm radiator and that you have three 120 mm fan positions available. The X-Flow design works best when the loop can supply the high flow rates the internal geometry is built for.

Questions about this item

How do I mount the 360 mm radiator and which step do builders often miss?

Align the radiator with three 120 mm fan slots, use the included mounting hardware and screw plugs, then double-check that both chamber ports are sealed before filling the loop — the plugs are the step most often forgotten.

What maintenance will this full-copper radiator need over time?

Flush the loop once a year with distilled water and a non-corrosive biocide; the copper fins, channels and chambers resist oxidation but still benefit from fresh coolant to prevent buildup.

What limit appears first when the X-Flow design runs at sustained high flow rates?

The 30 mm core thickness caps thermal dissipation before the bevelled X-Flow chambers reach their flow ceiling, so coolant temperature rise becomes the bottleneck under continuous load.
