For
testing, we decided to test the cooler by using
Arctic Ceramique thermal compound. We placed a
layer on the CPU and left the system working in
order for the thermal paste to stabilize for about
24 hours. The Thermalright SI-128 does not come
with any fan, so we chose a Revoltec 120mm LED
fan for testing it. We imagined that using a fast
and noisy fan is not a realistic scenario. The
Revoltec fan only spins at 1200RPM and creates
less than 22dBA of noise, which makes it entirely
silent while it isn’t too slow, making it
a good match for the SI-128 inside an everyday
enthusiast system. CPU load was achieved by running
Prime95 torture test (blend) and Super Pi simultaneously
for 30 minutes. The idle temperature measurements
were noted after the system was resting at the
windows desktop for 30 minutes. Ambient temperature
is maintained (as accurately as possible) at 25
degrees Celsius at the time of the test. SpeedStep
is disabled.

From
the above results we can see that there is a significant
difference between the idle and load temperature
readings. This is because of the rather slow fan
we chose and the fact that the SI-128 is still
an air cooler, despite its excellent design. Nevertheless,
the performance of the SI-128 is above admirable.
Our E6400 Allendale core is a real thermal monster
when overclocked and still the SI-128 kept it
cooler than the stock cooler could at stock speed
and voltage! Its performance may not reach that
of watercooling systems, but nonetheless it performs
close enough to have any enthusiast think twice
before spending many times more money for a complicated
cooling system.
