Announcing S-PAL8952 Heat Sink for Pentium 4 (socket 478)
We would like to introduce a new Intel Pentium 4 heat sink, the S-PAL8952.
This heat sink is for Socket 478 processors. Compared to our current P4 heat sink,
we have increased the size and changed the fin pattern. Due to these changes,
we have been able to improve the performance.
The performance improvements make this heat sink the ideal choice for the new
Prescott, Northwood and Extreme Edition processors from Intel, which run much
hotter than the previous Northwood chips.
Some of the features of this heat sink:
The S-PAL8952 shares many design features
with the current PAL8942. They both mount
through the four holes surrounding Socket
478. We increased the fin length by 10 mm
and changed the fin pattern. The new fin
pattern design is based on the air flow within
the heat sink. The shape of the outside pins
is square and inside pins are round. The
intake cover is longer to prevent any air
from taking a short cut past the hottest
portion of the pins. These changes have improved
the airflow and thermal performance of the
According to our test results, we have improved
performance with both high speed and low
