||The Heatsink Fan: |
fan is set into the body of the Asus StarIce heatsink, a
few millimeters in front of the copper fins. The fan draws power
from a standard 3-pin motherboard connector that supports
RPM monitoring. Another two-pin connector hooks into the thermistor to enable temperature controlled fan speed mode.
The large blue plastic shell is 117mm in diameter.
The 40 stacked copper fins
are spaced 1.5mm apart, and individually measure about 0.1mm
thick. Three 6mm diameter heat pipes intersect the copper fins at six
positions to distribute the heat energy from the base plate evenly over a
larger surface area. The copper base plate
varies in thickness between 6mm and 3mm thick, and is rather roughly finished.
The top of the Star Ice is enclosed with a clear plastic shield emblazoned with the ASUS logo. The area below
has no ventilation paths, and this results in hot stagnant air pooling at the top of the heatsink. Two small blue LED's illuminate the logo, but frankly this kind of design choice in a heatsink is just perplexing... It ultimately diminishes the thermal performance of the Star Ice heatsink.
Heatsink Side A:
The Asus Star Ice is visually appealing from the outside, but apparently the engineers gave little to no thought about how all the plastic would impact the heatsinks' performance. From the side we can see part of the copper fins which are responsible for dispersing heat into the surrounding air. Note that the upper portion of the heatsink is completely enclosed. The Star Ice stands 143mm tall, front to back it is 114mm deep.
Heatsink Side B:
At the rear of the Star Ice, Asus have added some screw holes
where users can install a separate 80mm exhaust fan (not included). Looking down
the barrel of the heatsink, the six sections of copper heatpipe
are easily visible intersecting the copper fins.
The copper base of the Asus Star
Ice heatsink is poorly finished, its sanded treatment translates into
a surface roughness of about 64 microinches. The copper is flat in
one axis, and very slightly convex in the other (perpendicular
to the heatpipes). This is not overly surprising given that the material goes
from 6-3mm thick at the center.
