Our Take

A dual-tower air cooler from Noctua aimed at anyone wanting near-silent, high-end thermal performance without moving to liquid cooling. Its 165mm height means a spacious case is essential, but in return you get cooling capacity that rivals many all-in-one liquid coolers, backed by Noctua's famously long-lived fans and rock-solid mounting system.

Key Features

Dual-tower heatsink with six nickel-plated copper heatpipes for heat distribution

Two NF-A15 140mm PWM fans included, running in a push-pull configuration

SecuFirm2 mounting system supporting Intel LGA and AMD AM4/AM5 sockets (check compatibility list for latest chips)

Low-Noise Adaptors included to cap fan speed and cut noise further

NT-H1 thermal paste included in the box, no separate purchase needed

Approximately 165mm tall, so case clearance needs checking before buying

Our Verdict

Buy this if you want quiet, high-end air cooling and have a case big enough to fit it. It's overkill for basic office PCs and a poor fit for compact builds, but for enthusiasts prioritising thermals and acoustics over looks, it's hard to beat.

What We Like

  • Excellent cooling performance even under sustained heavy load
  • Genuinely quiet running, especially with the Low-Noise Adaptors fitted
  • Robust, fiddle-free mounting hardware that feels built to last
  • Long warranty reflects real confidence in longevity

Things to Consider

  • Very tall and wide; will clash with tall RAM or small cases
  • Front fan can overhang the top RAM slot on some motherboards
  • Not the most attractive cooler if you're going for an all-black or RGB build
  • Heavy, so worth checking your motherboard can support the weight long-term
