Noctua NH-D15 vs Corsair iCUE H100i Elite Capellix

Both are real cpu cooler options from our cpu coolers guide. Specs below are taken from each product's own listing — we don't run benchmarks or invent performance numbers.

Noctua NH-D15

Noctua NH-D15

Dual-tower air cooler with two 140mm fans — a long-standing benchmark for high-end air cooling performance and reliability.

Specs

  • Dual-tower air cooler
  • Two NF-A15 PWM 140mm fans
  • 6 heatpipes
  • 165mm height
  • 6-year warranty

✓ Best for

High cooling performance with no pump to eventually fail — the long-term-reliability choice in enthusiast cooling.

⚠ The tradeoff

165mm tall, so check case clearance, and it can overhang RAM slots. The brown/beige colour scheme is divisive in a windowed build.

Corsair iCUE H100i Elite Capellix

Corsair iCUE H100i Elite Capellix

240mm AIO liquid cooler with RGB fans — a common mid-to-high-end liquid cooling pick with software-controlled lighting.

Specs

  • 240mm AIO radiator
  • Two 120mm RGB fans
  • Capellix RGB LEDs
  • iCUE Commander CORE included
  • Intel LGA 1700 / AMD AM5 support

✓ Best for

Builds where clearance around the CPU socket is tight, or where the cleaner look of a radiator matters aesthetically.

⚠ The tradeoff

Adds a pump as a wear component that a high-end air cooler doesn't have, and needs a case with a compatible 240mm radiator mount.
