Scythe Ashura Review


Scythe Ashura Testing:

Testing of the Ashura 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 27 °C and after the load is applied, we hit 67 °C.  These temps are just fine, and the 67 °C under a load is right about where I expected. In fact, we are right there with the NZXT X31, which is a liquid AIO (All-in-One) cooler. And we are just a degree higher than the formidable Cooler Master Nepton 240M. The Ashura is looking real good so far.

Now, after we crank up the overclock, the idle hits 32 °C, which puts us in the middle of the tested coolers. Under a load (overclocked), the Ashura comes in at 79 °C, which is again sort of in the middle of the pack, but nowhere near the danger zone.  In fact, it is in between the Maelstrom 240 and the NZXT X31, which are both liquid coolers. No surprise that the large liquid coolers come in at the top three positions (lowest temps). Nevertheless, the Ashura has proven itself to be a capable unit.  For daily use or mild overclocking, the Ashura can handle the job. And if you add a second fan, I suspect that the temps may come down a degree or two.

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