    Pump Failure After Just Two Months of Use

    I purchased the Kraken Elite RGB 420 directly from NZXT’s official store, expecting a premium product backed by a 6-year warranty. Unfortunately, my experience has been deeply disappointing.

    At first, the cooler seemed to work, though I noticed from the very beginning that at pump speeds below ~70%, there were audible bubbling noises. To avoid this, I set the pump curve to run at 80–100%. I didn’t think much of it at the time, but in hindsight, it was an early sign of trouble.

    After only two months of use, the pump completely failed. During one normal operation, the system fans suddenly ramped up and the CPU temperature spiked to 106C, forcing an emergency shutdown. Since then, the system either shut down within seconds of booting or showed a CPU error. When I managed to open NZXT CAM, it clearly reported the pump at 0 RPM, while CPU temperature climbed rapidly to 97C. The LCD screen and fans still worked, but the pump no longer circulated coolant at all.

    I confirmed the issue wasn’t installation, thermal paste, or cabling — the LCD and fans, both powered by the same SATA line, were functioning fine. The failure is isolated to the pump itself. For a product marketed as a high-end, long-lasting AIO with a 6-year warranty, a total pump failure in just two months is unacceptable.

    I’ve since removed the unit and will be submitting an RMA request, but this experience has shaken my confidence in NZXT’s quality control. Buyers should be aware that, while the Kraken Elite looks…

    Hi S.Z.,

    I am very sorry to hear about the pump failure you experienced with your Kraken Elite 420 RGB after just two months of use. I can see that you've thoroughly diagnosed the issue and confirmed it's isolated to the pump itself, which shows this was clearly a product failure rather than any installation issue on your part. We will make sure to follow up through your ticket and get his replaced as soon as possible.

    We value you as a customer and will make this right. Your detailed feedback about this failure is also important for us to continue improving our quality control processes.

    Thank you for taking the time to share your experience and for your patience during this disappointing situation.

    How does this even happen?

    I had the 360mm version of this but got the new h9 flow case so got the 420mm kraken but this one has issues.

    I don’t know how this is even possible but the entire thing is crooked. The fan and AIO holes don’t align. They aren’t even close to aligning. Amazon ended up refunding $70 out of the total and I kept it. Really unacceptable for a $330 piece of plastic. This is not user error, I’ve built probably 6 computers by now and always rotate out parts.

    The AIO is great though. Keeps everything cool and looks good.
