Pros & Cons
Pros
- ✓ 3,100 RPM pump handles sustained gaming and multitasking loads
- ✓ 240 mm radiator with a single-frame fan fits most mid-tower front mounts
- ✓ Plugs straight into the motherboard, no separate NZXT controller needed
- ✓ PWM fans let you dial in curves per your own thermal targets
- ✓ Fits LGA 1851/1700/1200/115X and AM5/AM4 without buying a new bracket
Cons
- ✗ Single-frame fan design means you cannot swap in one replacement fan
- ✗ No LCD or infinity-mirror display like NZXT's pricier Kraken Elite line
- ✗ RGB runs off the motherboard header, so lighting depth depends on your board
- ✗ 240 mm class trails 360 mm AIOs on overclocked high-TDP chips
