Alpha PAL6035
In September 2000, Alpha started shipping the PAL6035 with a different clip, which is optimized for AMD CPUs. The new clip is stronger and has a revised (smaller) pressure point, and therefore improves cooling performance. Of course we tested with the new clip.
Finally, in November 2000, an updated version of the PAL6035 hit the market, which is compatible with all Socket CPUs from Intel and AMD. It has modified base plate and optional little feet that can be sticked on the heatsink if it should be used with FCPGA CPUs. Performance-wise, the latest Alpha is on par with the previous version with the revised clip.
Not all Alpha PAL6035 are created equal - there are many different versions, so if you plan to buy a PAL6035, make sure you get the latest version.
Alpha ships the heatsinks
either without fan, or with Sanyo Denki fan. Many retailers buy the heatsinks
without fan, and add fans from other manufacturers, because they are cheaper
and often more efficient. The most popular and most widely available 60x25mm
fan is the YS Tech fan, supplied by Global WIN. Therefore we test the Alpha
both with the original Sanyo Denki fan, and the YS Tech fan.
These two images
above show your the differences between the old PAL6035 (left) and the new
PAL6035 (right).
The new model is also milled
on the upper side, and has little circles in the base plate that show where
to install the optional pads for Intel FCPGA CPUs.
One problem with
all copper heatsinks is that in the long term, most thermal compounds will
enter a chemical reaction with the copper base.
On the second heatsink, you can
clearly see the traces where thermal compound had been applied.
