Kraken Core 240 RGB

Q: What’s the best way to connect and sync RGB lighting on pump cap and fans?

Use your motherboard’s 5V ARGB headers: If your motherboard has more than one header: Plug the pump cap and fans into separate headers for more individual control. If your motherboard has only one header: Daisy-chain them by connecting the fan’s 5V female connector to the 5V male connector from the pump cap, then plug that into the single header. Both methods work. Using separate headers gives you individual control, while daisy-chaining keeps the cap and fans perfectly in sync.

Overview

NZXT Kraken Core AIO levererar kraftfull, tyst vätskekylning med en högpresterande pump, PWM-fläktar och levande RGB-belysning. Enkel att installera och kompatibel med de senaste Intel- och AMD-socklarna håller den din CPU sval, ditt system tyst och ditt bygge snyggt.

Svalt och tyst: En kraftfull 3 100 RPM-pump håller din CPU sval under intensivt spelande och multitasking, samtidigt som ljudnivån minimeras.
Enkel anslutning: Ansluts direkt till ditt moderkort för enklare kabelhantering och snabbare bygge – inga extra styrenheter krävs.
Optimerade fläktblad: RGB Core-fläktar (EV-B-version)* med högt statiskt tryck pressar effektivt luft genom kylarens lameller för starkare kylning med mindre ljud.
Justerbara fläktkontroller: PWM-aktiverade fläktar möjliggör exakta justeringar för effektiv prestanda som du kan anpassa efter din installation.
Enkelramsdesign: Flera fläktar i en solid ram minskar antalet skruvar och kablar, vilket gör installationen enklare och ditt bygge snyggare.
Enkel installation: Verktygsfria fästen, förpålagd kylpasta och flexibla slangar gör installationen snabb och problemfri.
Strålande RGB: Anslut till ditt moderkorts 5V ARGB-kontakt. RGB-effekter styrs via ditt moderkorts belysningsprogramvara.
Redo för Intel eller AMD: Inkluderar monteringsutrustning för de senaste AMD®- och Intel®-socklarna, inklusive AM5 och LGA 1851.

*EV-B-version: Kraken Core-exklusiv 5V ARGB-enkelramsfläkt. Inte den fristående F RGB Core-butiksfläkten.

Strong Cooling. Streamlined Design.

Kraken Core delivers reliable liquid cooling with vibrant RGB and a clean, builder-friendly design. It’s a great fit for new builds, upgrades from air cooling, or anyone who wants quiet, reliable performance in a streamlined setup.

Cool and Quiet

A powerful pump keeps CPU temperatures under control during heavy gaming or multitasking, running at 3,100 RPM to deliver efficient cooling with minimal noise.

Optimized Fan Blades

High static pressure fans push air through radiator fins for stronger, more efficient cooling.

Single-Frame Design

Multiple fans in one solid frame—fewer screws, fewer cables, cleaner build.

Easy Installation

Tool-free brackets and pre-applied thermal paste make setup quick, clean, and frustration-free.

Frequently Asked Questions

What’s the best way to orient the tubing with the Kraken Core pump cap?

For best performance and reliability, route the tubes from the right side of the pump. This helps prevent air bubbles from collecting in the pump, which could otherwise cause noise or reduce cooling efficiency over time.

Keep in mind that the pump cap logo has a fixed orientation, so the appearance won’t change if you rotate the cap.

Do I need NZXT CAM software to control Kraken Core?

No. Kraken Core connects directly to your motherboard for both cooling and lighting. The fans connect through a PWM cable you control in your BIOS or motherboard software, while the RGB plugs into a 5V ARGB header for lighting effects.

You can still use CAM alongside Kraken Core if you’d like. While it doesn’t directly control the cooler pump speed, CAM lets you monitor system performance and sync lighting across other NZXT products.

Why do Kraken Core fan speeds look inconsistent in BIOS and software?

Some early Kraken Core units may show jumpy RPM readings in BIOS or monitoring software due to how the tachometer (TACH) signal is reported. The fans themselves run smoothly, cooling and noise are unaffected. RPM readings also have a normal tolerance of about ±250 RPM (10%) above or below the maximum value. Later units were updated to provide a more stable signal, but if you see this behavior, there’s no need to replace your cooler.

What’s the best way to connect and sync RGB lighting on pump cap and fans?

Use your motherboard’s 5V ARGB headers:

If your motherboard has more than one header: Plug the pump cap and fans into separate headers for more individual control.
If your motherboard has only one header: Daisy-chain them by connecting the fan’s 5V female connector to the 5V male connector from the pump cap, then plug that into the single header.

Both methods work. Using separate headers gives you individual control, while daisy-chaining keeps the cap and fans perfectly in sync.

Can I adjust the pump speed on Kraken Core?

No. The pump is designed to run at a fixed speed and doesn’t support speed adjustment. Attempting to change the speed through third-party software may cause damage. In your BIOS, we recommend setting the pump header to run at full speed.
