Core 360 RGB liquid cooler

The NZXT Kraken Core 360 RGB is a new all-in-one CPU liquid cooler with a 360 mm radiator and integrated single-frame fans. It targets builders who want straightforward liquid cooling without separate controllers or extra cabling. The package includes mounting hardware for current AMD AM5, AM4 and Intel LGA 1851, 1700, 1200 and 115X sockets. Buyers needing smaller radiators or air coolers should look elsewhere.

360 mm radiator with 3100 RPM pump

A 3100 RPM pump circulates coolant through the 360 mm radiator to handle sustained loads from gaming and multitasking. Three 120 mm high-static-pressure fans push air through the fins, and PWM control lets the motherboard adjust speeds for the thermal headroom required. The cooler runs out of capacity when the CPU heat output exceeds what the radiator surface and fan airflow can dissipate.

Single-frame fan and motherboard ARGB

The EV-B version fans share a single frame, reducing screw count and cable clutter during installation. Tool-free brackets and pre-applied thermal paste speed up the mount, while flexible tubing eases routing in tight cases. Both pump and fans connect to a 5V ARGB header, so lighting is managed through the motherboard software without a proprietary controller.

Questions about this item

Will the 360 mm radiator and single-frame fans fit in a case designed for 120 mm fan mounts without blocking RAM slots?

The 360 mm radiator uses three 120 mm fan positions in a single frame, so it fits standard 360 mm top or front mounts; the pump sits on the CPU socket and clears most tall RAM, but verify your case clearance and motherboard layout before installing.

How can I confirm the 3100 RPM pump and PWM fans are running correctly after installation?

Check pump RPM in BIOS or monitoring software — it should report near 3100 RPM under load; fan speeds should scale with CPU temperature via PWM curves, and RGB lighting on both pump and fans will activate once the 5 V ARGB header is connected and motherboard software is configured.

Does the box include mounting brackets for AM5, AM4, LGA 1851, 1700, 1200 and 115x sockets, and is thermal paste pre-applied?

Yes — brackets for all listed AMD and Intel sockets are included, thermal paste is pre-applied on the cold plate, and the single-frame fan assembly ships attached to the 360 mm radiator; no separate controller or additional paste is required.
