In the event of a potential RMA or warranty claim for your NZXT product, you may be asked to provide the Serial Number and Product/Model Number for your product. To help with this process, a list of common locations can be found below:
Damaged or Removed Serial Number
NZXT's product warranty is only valid for products with a complete, undamaged serial number. If a serial number has been found to be altered, damaged, removed, or otherwise tampered with your warranty claim will be rejected. No exceptions are offered to this policy.
Kraken series AIO CPU Cooler
For all Kraken series liquid coolers, the Serial Number and Product/Model Number will be located on the radiator of the core assembly.
Kraken Elite (2024 & 2025)
Located at the base of the tubes on the fan side of the connecting block. Accessing this sticker will require removing the attached fan(s).
Kraken (2023), Elite (2023), Plus, Core, X, and Z
Located at the end of the radiator opposite of the tubes.
Kraken M22, 120, and H1
Located at the end of the radiator on the tube side.

Case and Radiator Fans
Depending on the model of the fan, the serial number will be located either on the fan body (Aer RGB 120 shown above), center hub, a sticker flag on the power cable.
RGB Controllers & Case Accessories
For all RGB Controllers, Fan Controllers, and other Case Accessories such as the USB Hub (shown above), the Serial Number & Product/Model Number can be found on the underside of the product.
NZXT Peripherals and Gaming Accessories
Gaming Gear & Audio
For NZXT Gaming Gear such as the Function series keyboards (shown above), Lift series mice, and Audio products such as the SwitchMix, the serial number can be found on the underside of the product.
Function Elite Keyboard & Reset Switch
Because the Function Elite Keyboard features a reset switch beneath the serial number sticker that requires a puncture to access, this is the only exception to the undamaged serial number rule. Only the puncture is allowed to be present, any other signs of damage or tampering will be rejected.

For the NZXT Relay Speakers, the serial number can be located on the rear of the powered speaker (left, shown above).
Do I need to register my NZXT product?
As of September 2026, we do not offer product registration for NZXT products, however this may change in the future. For any warranty claims, please be sure to hold on to your original purchase invoice or receipt as this is required for all warranty claims. No exceptions will be offered.
