NZXT Kraken G10 Testing:

Testing of the Kraken G10 will be accomplished by installing the bracket along with the X31 into the test system GPU / case, rather than a test bench. Most systems are built and mounted into a (relatively) sealed chassis, so this method will be used to generate the idle and load results to give a real world view as to the cooling performance one can expect, based on the test system listed below. Of course, your results may vary by several degrees due to case design, case fan placement, ambient air temperature, and the method used to stress the CPU.

The GPU load is generated by using 3DMARK as well as GPU Folding, Call of Duty 4, and Battlefield 4.  Ambient temperatures are kept at 24 °C during the testing to minimize the effect of temperature variations. The system was tested with the manufacturer-supplied thermal compound as delivered.

 

Testing Setup:

 

Comparison Coolers:

  • Stock NVIDIA GTX 670 Reference Graphics Card
  • NVIDIA GTX 670 Reference Graphics Card with G10 and X31 AIO cooler (single fan)
  • NVIDIA GTX 670 Reference Graphics Card with G10 and X31 AIO cooler (dual fans)


 

 

After running the tests with the single fan that is included with the X31, I decided to see how much more of a temperature drop I could get with two fans. I still had one of the Cooler Master JetFlo 120 fans left, so I installed it in a push-pull configuration, with the JetFlo being in the pull location.  This knocked a few more degress off the top. I should also mention that I plugged the JetFlo into an open fan header on my motherboard, but the X31 can control two fans, so you are able to plug both fans into the X31.

 

The three things that I do that regularly load my GPU are playing COD4, Battlefield 4, and protein folding ([email protected]). While playing Battlefield, I typically see temps around 62 °C and folding temps are around  the mid 60s. COD4 is a bit cooler, usually in the mid 50s, and these temps are at stock GPU clock speeds.

Idle temperatures come in at 27 °C and the load temps are amazing, with an average drop of around 23 °C in folding and the games that I play. The 3DMark testing did not go above 42 °C, which is about a 25 °C improvement. Impressive, yes, but also not a huge surprise. Water cooling a GPU is typically a big step up from the factory air cooled heat sinks.
