Starting with the head unit, if you flip it belly up, you can see the convex copper base plate that takes the initial heat load from the processor, and through skived grooves in the back of the plate, the pump included in the head unit forces coolant through these grooves to remove the heat from the CPU. On the head unit of the X40, of course you have two black rubber tubes connected to the side, attached to swivel fittings to make installation cleaner and easier, but it also offers an assortment of cabling near these connections. On the end of the three braided leads that emanates from the head unit, there is a 3-pin fan connection to supply power to the pump which runs at 2900 RPM. The other two leads terminate in a USB connection so the software has a way to talk to these units, and the other lead ends with a pair of male 4-pin fan connectors to allow users to clean up the wiring to install the stock fan, or a pair of them for a push/pull setup.

 

After passing over 15 inches of rubber tubing, the longest in the industry, you then run into the aluminum barbs that the tubes have been connected to on the radiator. This radiator is of course made of aluminum, measures 27mm thick, and uses a fin count of 24 FPI. With this much surface area, and such a tight fin arrangement, it is going to take a really good performing fan to make this unit efficient. Here NZXT chose the FX-140RX-PWM fan. This fan offers 98.3 CFM at 2000 RPM. While it is powered with a 4-pin connection for PWM control, the static pressure rating of 2.2mmH20 should be sufficient enough to push through this radiator. On top of offering a two year warranty on these units, you can also see that they will mount up almost all of the CPUs in use today, providing the chassis they are in offers a 140mm fan hole in it.

 

Since these cooling solutions have been on the market for over a month now, finding the X40 online was not very tough at all. Currently the best deal that I see is at OutletPC.com with a listing of $92.93, shipping included. While there are a couple more listings before I ran into the Newegg.com price, OutletPC and Newegg I have at least used over the years, and can say you will get what you pay for with them. While the price does increase about $2 if you shop at Newegg.com, I am sure more people will go there just for the familiarity and security in the purchase.

 

Coming in at just under $100 is a good start to trying to dominate the AIO cooling segment, but there is more than just simple specifications and a lower price to keep in mind. Let's get into the finer details of the Kraken X40 from NZXT and see how much cooler you get at this price.
