NZXT Kraken X40 Liquid CPU Cooler - Testing:

Test Setup:

For Intel (LGA1336) testing we will be using the Intel Core i7 920 CPU, which produces 130 Watts of heat. Most current CPU's produce considerably less heat than the Intel i7 920 but this should give you a very good idea what to expect performance-wise when compared to other coolers that we've reviewed.
 

For both AMD and Intel testing, we have taken all temperatures using CoreTemp v.0.99.4. CoreTemp takes a temperature from the CPU core, and allows for much more uniform results across different motherboard and CPU platforms. These temperatures may seem higher than other temperature recordings; because chances are they are taking temperature recordings using the diode underneath the CPU, which isn't able to be as accurate, and can really fluctuate between different brands of motherboards.
 

For all tests we are using the Highspeed PC Top Deck Tech Station , and we are using no additional cooling in our testing. All temperatures are recorded in a controlled environment that is set to 23 degrees Celsius (73.4 Fahrenheit) to provide fair results between coolers.

For all tests we use Arctic Cooling MX-2 High-Performance Thermal Compound (Paste), We use the same thermal paste in all our testing so that we can keep our results consistent. If a cooler is shipped with thermal paste pre-applied, it will be removed and we will re-apply it with Arctic Cooling MX-2 to provide fair results.

Intel Test System:

 

For all of our testing of the NZXT Kraken X40 we have manually turned the fan on the radiator up to 100% (2000 RPM).

So as we can see from the first chart the Kraken X40 offers some pretty decent performance. Let's take these results and put them up against all of the other coolers we've taken a look at.

The results are in.

As you can see from the chart above, the Kraken X40 did very well in our testing and was only beaten by one other cooler. The Thermaltake Water 2.0 Extreme was able to beat the Kraken X40 by 2 degrees, but when you consider that the Kraken X40 has a MSRP of $100 USD and the Water 2.0 Extreme has a larger radiator and a MSRP of $130 USD I would say the Kraken X40 did very well.

Overall I would say that I was expecting the Kraken X40 to do well, but it exceeded my expectations by a couple degrees with its performance.

Let's move onto the final section of this review where we provide a final score for the Kraken X40.
