Cooling efficiency
The results of our cooling efficiency tests
on Evercool Silent Shark and its opponent in an LGA 2011 platform are given in
the following table and diagram:

Frankly speaking, we do not expect Silent
Shark Evercool will do well: the maximum and average speed of its two fans
successfully compete with Phanteks PH-TC14PE! Of course,Evercool Silent Shark
has a dual-array aluminum heatsink with larger effective surface, six copper
heatpipes 6 mm in diameter, two fans, highly reliable retention with high
pressure hold, but we have tested many types of coolers that also have all the
above factors, and none of them can be considered a worthy opponent for
Phanteks. Here, by contrast, we see very good cooling performance even with
nominal operation mode.
At the maximum speed of its default fans
Silent Shark is only 1⁰C behind PH-TC14PE, at the medium speed of 1640/1670 RPM
the difference is the same 1⁰C, though the Phanteks cooler works at only 800
RPM in this case. If we look at lower fan speeds, Evercool Silent Shark loses
very little efficiency. And the main reason here is the external cooling fan,
with the rotational speed can not be adjusted.
If we equip Evercool Silent Shark heatsink
with two identical Corsair cooling fans, which can be adjusted in sync, we'll
see a more vivid dependence of the cooling efficiency on the fan speed. It
would even be fair to call it linear, because every time the fan rotation speed
is lowered by 200 RPM (except for the first 600 RPM), the CPU temperature
increases by 3⁰C, and at 800 RPM the cooler could no longer bear the load that
is why the maximum temperature value is crossed out. In general, we can not assert
that using two alternative fan improves cooling efficiency of Evercool Silent
Shark. Maybe if we can install a 140 mm fan instead of a 120 mm one, we can
gain a few degrees C, but the plastic fan mounts of the Evercool Silent Shark
cooler do not allow that.
Now let's obtained results to summary table
and diagram, where all coolers are tested in their default configuration in
quiet mode and at maximum fan rotation speed. The processor in this case has
been overclocked to 4375 MHz with Vcore set at 1,385 V.

comparing the results
At maximum rotational speed of two default
fans, Evercool Shark Silent failure when standing after four super-coolers.
This is a great result, although in terms of sound, Silent Shark Evercool was
only better than SilverStone Heligon HE01. In relatively quiet mode when the
central fan rotates at 820 RPM, Evercool Silent Shark stays in the leading
group and outperforms such powerful competitors as Thermalright Macho or
Archon. However, it is important to keep in mind that the exterior fan of the
Evercool Silent Shark cooler doesn’t support fan rotation speed adjustment that
is why it will always spin at 1,600 RPM (1,400 RPM ±15%), according to its
official technical specifications.
After this test, we decided to check out what
Evercool Silent Shark likely to be at higher CPU clock. Unfortunately, none of
our numerous attempts engaging difference Vcore settings succeeded. Each test
ended up with an error.

As a result, Evercool Silent Shark cooler took
the leading position in our summary table and diagram for maximum CPU
overclocking, but only in the junior group:

Noise level
We measured the noise levels of the cooler
throughout the entire range of the fan's speed, as described in the content
about testing methods. Here are the results:
The
graph describes the noise level
As we see, Evercool Silent Shark has some
advantages when considering the same rotational speed. In fact, this is not
surprising, because it uses 120x25 mm fan instead of 140 mm fan on the Phanteks
coolers. Silent Shark still runs quite smoothly up to 1,030 RPM, while the
Phanteks PH-TC14PE has to reduce the fan speed to 700 RPM to stay within the
acoustic comfort zone. Maximum noise level of Phanteks is 47.7 dBA, at nearly 1,300
RPM, while the Evercool achieve the same noise level generated at 1850 RPM. In
other words, taking into consideration the previously obtained results of the
cooling efficiency tests for these two coolers, we can conclude they equal each
other actually. And we should give Silent Shark and Evercool in general due
credit: this is a truly unprecedented accomplishment.
Conclusion
The new Evercool Silent Shark cooler
surprised us with its significant cooling efficiency. Even though it is only
slightly behind the concept of the best of the best (in terms of maximum
processor overclocking), we must admit that this Evercool's product turns out
to be a great success. In our opinion, the potential of this cooling device is
not completely over, because all that we really need to remove is the plastic
cap, use traditional wire clips to attach two high-quality 140 mm fans with
synchronous PWM support in the 600-1,600 RPM range, and make a few
technologically simple optimizations to the fins in order to lower airflow
resistance. Then, Silent Shark from Evercool will win its rightful place among
the leaders in contemporary air cooling. However, despite the Evercool Silent
Shark cooler is new, it is very attractive due to its high performance and comprehensive
design, high durability, simple installation and the ability to redirect
airflow to the components around the processor socket.
