NZXT Introduces Kraken X41, X61 All-in-One Liquid Coolers

The Kraken X61The Kraken X61NZXT has announced its new Kraken X41 and Kraken X61 liquid coolers at their suite in the Grand Hyatt at COMPUTEX 2014, and they look like excellent successors to the older X40 and X60 liquid coolers. They carry 140 mm and 280 mm water coolers, respectively.

Both the units are built using Asetek's new Gen. 4.5 design which brings support for a variable pump speed. While many pumps can be slowed down through undervolting them, these pumps now officially support it through the software. The pumps can spin at speeds of around 3600 RPM when running at 100 percent.

The Kraken X41 now has a thicker radiator than found previously on the X40, improving thermal performance. Now at 35 mm thick, according to NZXT it was a worthy sacrifice to ditch compatibility with a small number of cases to improve performance by a very noticeable margin in every other.

The fans on the units have also been refreshed, and now feature thicker, stronger blades (our representative told us that apparently fan blades came off the hub from time to time with the older units when running at high RPMs), as well as better bearings, all in all which make fans put out a higher airflow to noise ratio. Combine that with the variable speed pump and you should be able to get some very low idle noise levels.

Of course, the water loops also come with support for NZXT's new CAM software, and soon it'll be possible to control multiple Kraken water coolers individually.

Pricing for the units is set at $109.99 and $139.99 for the X41 and X61, respectively, and they can be preordered immediately through the NZXT armory. Warranty is also now set at a massive six years, which NZXT claims is the longest warranty period available in the market.

Also, a special thanks goes out to Mitchell Podlaha, who gave us the tour at the suite.

    The name alone should assure their success. Of course temperatures are all too easy to measure so maybe not.

    I congratulate NZXT on revamping their Kraken line of coolers. I am more than impressed that they bumped up the warranty to 6 years which trumps Corsair by a whole year. It shows that they now have faith in their product where as other companies give you a simple 1 year or 2 year warranty.

    As for the X61, i was really hoping to see a combo cooler like the Asetek 760GC released just with a 38mm thick 280 rad but i can keep dreaming. If i did not already have a H80i i would jump on the X61 but waiting for NZXT to learn how to integrate their HUE lighting kit with their CAM software, this way they can be in direct competition with Corsair who seems to think it is fun to charge customers $29.99 for 9 LEDs in a kit and offer them no way of buying more LED strips unless they buy multiples of the kit even though their customers have been asking them to sell the LED strips separately for 2 years!!

    Seems pretty cool. I currently have the kraken x40 cooling my Phenom II x6 1075T overclocked and running at 1.56V. at load it can stay under 45C. (not sure how much it uses when overclocked, but at stock speeds and voltages, it pulls 125 watts)

    Only issue is due to my case, the Antec Three hundred, To install the cooler at the top of the case, I had to cut out the the top mesh material since it was not flush with the case, and then install the 140mm fan outside on the top of the case in a pull configuration (best configuration as it makes cleaning the radiator easy with a vacuum cleaner home.

    (my ugly build
    since it lacks good cable management, I keep the wires closer to the side panel part of the case so that the airflow over the motherboard does not get obstructed)
