Deepcool Assassin II Review


Deepcool Assassin II Testing:

Testing of the Assassin II will be accomplished by installing the cooler into the test system 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 CPU load is generated by Prime 95 version 27.9 for a period of two hours, with a cooldown period of one hour after the computer has returned to an idle state. Real Temp 3.70 is used to log the temperatures with the highest and lowest averages across the four cores of the Core i7 4770K test CPU. Ambient temperatures are kept at 24 °C during the testing to minimize the effect of temperature variations. Each cooler is tested with the manufacturer-supplied thermal compound as delivered.


Testing Setup:


Comparison Coolers:





Idle temperatures with no overclock come in at 26 °C, which is at the lower end of the test coolers, but there is only a five-degree Celsius spread on the idle temperatures, so within that range there really isn't a "bad" idle temperature. Now when we crank up the heat, there is a much wider range for the load temperatures and after the load is applied, we hit 70 °C. This temperature is just fine and to get much below that, you have to go with much more expensive high end air coolers or get into liquid cooling.

After we pump up the overclock, the idle hits 31 °C, which puts us again toward the lower end of the tested coolers. There is a ten-degree Celsius range for overclock idle. Under a load (overclocked), the Assassin II comes in at 74 °C, which actually places it toward the low end of the pack. What I also find interesting is the narrow spread between the load temperature of stock and overclocked. Amazingly, we actually come in a little better than two of the liquid coolers. So the Assassin II has proven itself to be a very capable unit.  Looks like that monster base and eight heat pipes give the Assassin II some extra kick.

As far as sound goes, at idle and light load, you can't really hear the fans. Under a full load, the fan sound becomes noticeable, but it blends in with the case fans and is certainly not a concern.
