Xigmatek HDT-D1284
The stock fan's model number is the same as the one on the HDT-S1283. It was a touch different, but the fan speed and noise level are more or less the
same.

Load Temp: CPUBurn for ~10 mins.
°C Rise: Temperature rise above ambient (20°C) at load.
°C/W: based on the amount of heat dissipated by the CPU (measured
78W); lower is better. |
Fan @ 12V: There was mostly turbulent noise combined with some buzzing. The
overall sound level was a bit distracting. Cooling performance was good,
not great. A far cry from the best tower heatsinks.
Fan @ 11V: The type of noise was similar, only less so. The buzzing became
more faint, but was still evident close-up. The overall sound would fall away
into the background if one was sufficiently distracted or concentrating on
another matter. Surprisingly, the temperature did not change from 12V. 24°C
above ambient appeared to be the limit of the heatsink's performance with
the stock fan and no additional airflow would help it further.
Fan @ 10V: At this level, the noise it produced was fairly benign, almost
pleasant. At close range there was some low-pitched buzzing. The CPU temperature
only increased by 2°C.
Fan @ 9V: The frequency of the buzzing slowed to the point where it was just
slightly ticking, but it was only audible from inches away. At one meter,
it blended away into the background. Thermal performance dropped by an additional
3°C.
Results with the stock fan were decent, though far from stellar. What's most
amazing is the spread of temperature readings: Only 5°C separated 1370
RPM from 550 RPM. Varying the airflow changed the CPU temperature very little
— that's a testament to the efficiency of the heatsink.
The reference fan improved the HDT-D1284's performance further, just as it
did with the VX. The Nexus 120mm delivered moderately better temperatures
with lower noise levels across the board.
