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.
