NZXT Kraken X41 CPU Cooler Review


<< PREVIOUS            NEXT >>

CPU Cooler Final Thoughts

Although we are aware of how successful the NZXT Kraken X41 CPU Cooler has been since it’s release, it comes to us as no surprise. The X41 is the worthy successor of the X40, bringing even better performance, a ton of upgrades, and an even better warranty. We would have liked NZXT to provide a better fan, or even to include a second one, considering the price at which the NZXT Kraken X41 retails for. However, the addition of appropriately braided cables, long tubing, an RGB LED implementation that adorns the outer shell of the CPU core, and support for NZXT’s CAM software make the X41 one impressive cooler.


NZXT Kraken X41 CPU Cooler Ultimate Conclusion

In both of our performance tests the NZXT Kraken X41 managed to keep our I5 470k under adequate temperatures, even when overclocked to 4.2 GHz. When compared to other coolers, the NZXT excelled in it’s out of the box performance with the included 140 mm fan, but being a lot louder than the competition. Using two 140 mm Yate-Loon fans and custom TIM, we were able to achieve really similar results while lowering the noise, but when compared to the competition, the thicker and denser rad makes it hard for our low-noise fans to dissipate the same amount of heat as with other coolers.

Unfortunately, it is impossible for us to test the reliability of most of the products we review. However, the NZXT Kraken X41 shows some very positive signs when it comes to it’s overall construction. The mounting mechanism is sturdy and showed no signs of flex. The fins on the radiator were not easily bent, and the radiator has the appropriate spacing between the screw mounting holes and the fins. NZXT also offers a 6 year warranty, something we have seen trending from many manufacturers using Asetek designs.

To ensure compatibility, NZXT has added extra length to the tubing of the Kraken X41. Measuring 400 mm, you could mount the X41 in almost any case that has space for a 140 mm radiator at the top, back, or even the front of the case. Installation is really simple, without any unnecessary small parts that can be easily lost. The flexible tubing is not easily kinked, this would allow the X41 to be mounted in small form factor cases.

Our last score pertains to the value of the product at hand. The NZXT Kraken X41 is priced online for $89.99 (B&H | Newegg Amazon) at the time of this review which is a premium over most coolers released in 2015. NZXT justifies this with the many features the Kraken X41 offers which include a 6-year warranty, exceptional looks and customization, and great performance. Is it worth it? That depends on the buyer, it is clear that the Kraken X41 is one of a kind, but if you are a buyer in a budget there are clearly better options.

    Some of your charts are showing Kraken X61 results. Isn’t this an X41 review?

      Thank you for bringing this up. This was a typo and it has since been corrected. If you are looking for our Kraken X61 review stay tuned as it will soon be released!

        Nope, just pointing it out to you. X61 sounds like a good one. It’s good to know that the X41 is good enough for my PCs.

        I have the X41 here, but never used it. I have a pair of Noctua 140mm fans to use with it, or a pair of Cougar Vortex 140mm fans.

        I can put it into one of three builds and haven’t made up my mind yet.

    I read the text and on pages 5 and 6 x61 is used 5times and x41 is in the same paragraphs making it extremely confusing. I just got to the end to read that you corrected the x61 mistakes but , not where I just got through reading. I dont know if you had intermixed the x41//61 on the graphs , too, or if the text errors were separate
    I was confused as to just which Krakens were actually tested
