Spire SP411C5 QuieTude II Heatsink Review
heatsinks come from? A simple question to be sure (they come from a
factory), but I often find it rather remarkable just how spread out around the world most heatsink
manufactures are. Take for example Spire. Spire's offices are in the US,
Taiwan and the Netherlands, but the heatsinks are manufactured in China.
The Pentium 4-based Spire SP411C5 has traveled far to
come to the FrostyTech test labs, so let's not postpone the evaluation further!
Sitting in front of us we have a m478 heatsink designed to cool the processor
with a moderate amount of noise, scaling fan RPM as things heat up. At 300RPM
the SP411C5 is good in the noise department, but at higher temperatures it
can get somewhat loud.
Chances are, with good case ventilation most computers
will never reach this high-RPM plateau, but after a few hours of gaming you
never can really tell for sure. In any case, the SP411C5 comes packing a 45mm
copper disc which has been inserted into the base to improve thermal
conductivity between the processor and the rest of the heatsink.

To keep the SP411C5 in place
on the m478 HSRM, Spire have opted for a rather unique means of
mounting the heatsink. It still sits in the plastic HSRM of course, but rather
than clumsy clips it uses a set of integrated spring tensioned grabbers to lock
flick of a lever 180 degrees the heatsink grabs on to the plastic
HSRM and locks in. Heck, the SP411C5 even arrives with pre-applied white silicon thermal
compound applied to the base so installation is quick, easy, and literally just a
