  • Full-copper chambers boost heat transfer

  • 45 mm core thickness maximises surface area
  • Triple 40 mm fan support for high static pressure
  • 147 mm length fits standard 120 mm mounts

Compact 45 mm radiator for custom loops

The Alphacool NexXxos XT45 is a 120 mm full-copper radiator measuring 147 x 40 x 41 mm and built for DIY water-cooling systems. Copper chambers, fins and channels handle heat transfer while steel side panels and brass threads provide structural strength.

Triple 40 mm fan mounting and dual 6 mm barbs

Three 40 mm fan positions let builders push or pull air through a 12 FPI core without requiring larger 120 mm fan frames. Two 6 mm barbs accept standard soft-tubing fittings so the unit integrates into existing loops with no proprietary connectors.

Suits space-constrained builds needing high density

Builders with tight case clearance who want copper thermal performance in a 45 mm thick profile will benefit. Users requiring larger tubing IDs, higher fin density or standard 120 mm fan spacing should consider other form factors.
