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

De NZXT Kraken Core AIO levert krachtige, stille vloeistofkoeling met een hoogwaardige pomp, PWM-ventilatoren en levendige RGB-verlichting. Eenvoudig te installeren en compatibel met de nieuwste Intel- en AMD-sockets, houdt hij je CPU koel, je systeem stil en je build er strak uit.

Koel en Stil: Een krachtige 3.100 RPM pomp houdt je CPU koel tijdens intensief gamen en multitasken, terwijl geluid tot een minimum wordt beperkt.
Eenvoudige Aansluiting: Sluit direct aan op je moederbord voor eenvoudiger kabelbeheer en een snellere build—geen extra controllers nodig.
Geoptimaliseerde Ventilatorbladen: RGB Core (EV-B Versie)* ventilatoren met hoge statische druk stuwen efficiënt lucht door de radiatorvinnen voor sterkere koeling met minder geluid.
Instelbare Ventilatorregeling: PWM-ventilatoren maken precieze aanpassingen mogelijk voor efficiënte prestaties die je kunt afstemmen op jouw setup.
Enkelframe-ontwerp: Meerdere ventilatoren in één solide frame verminderen schroeven en kabels, wat installatie eenvoudiger maakt en je build netter.
Eenvoudige Installatie: Gereedschapsvrije beugels, vooraf aangebrachte thermische pasta en flexibele slangen maken de installatie snel en frustratievrij.
Stralende RGB: Sluit aan op de 5V ARGB-header van je moederbord. RGB-effecten worden aangestuurd via de verlichtingssoftware van je moederbord.
Klaar voor Intel of AMD: Inclusief montagemateriaal voor de nieuwste AMD®- en Intel®-sockets, waaronder AM5 en LGA 1851.

*EV-B Versie: Kraken Core-exclusieve 5V ARGB enkelframe-ventilator. Niet de losstaande F RGB Core retailventilator.

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.

Ready for Intel or AMD

Includes mounting hardware for the latest Intel® and AMD® sockets, like LGA 1851 and AM5.

Simple Connectivity

Connects directly to your motherboard—no extra hubs or controllers needed. Fewer cables mean faster setup and easier cable management.

Radiant RGB

Customize pump and fan lighting using your motherboard’s 5V ARGB header. Just plug in and personalize your setup for a clean, unified look.

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.
