Socket-A Heat Sink Roundup

What's on the grill?:
In this roundup I have compared 11 different coolers from 5
different companies. All are Socket-A compatible, and some can even be used in
Socket-370 (FCPGA) applications. First off, I would like to thank GlobalWinUSA
for supplying me with the WBK38, Heatsink
Factory for the FOP38, VantecUSA
for the FCE-62540D, TRIG
for the T40-1 & T40-3, and OCZ
for their various line of coolers.
The actual lineup of coolers is as follows:
As you can see, there are some coolers in the list that have
been around a while, and some that are brand new. I would like to discuss each
of these coolers in a little bit more detail, along with showing pictures
of various features of each cooler.
Alpha has been making the PAL6035 for quite some time. I still
have one of the older versions that is all aluminum and has less pins it it.
Over time it has undergone several revisions such as the copper base, increased
pin density, and anodized surface. You will notice that there is no finger guard
on the cooler but that is because I purchased just the bare heatsink since I had an
extra delta sitting around here doing nothing. The picture on the right you will
notice 4 little ring indentions on the surface, that is because Alpha supplies
you with little rubber feet that stick to the heatsink for FCPGA applications, but for Socket-A
do not, and should not use the little rubber feet since AMD CPU's already have
rubber pads on them.
Next up is Alpha's PEP66, which was originally intended for
FCPGA Slotket applications, however its popularity has spread to be mounted directly
onto the motherboard. In order to fit on the KT7, several stores have offered a
Delta low profile (10mm thick) 22CFM fan with the PEP66. You will notice I only
have two screws holding the fan down, the bottom two stick out too far and would
break off two capacitors on the motherboard if I left them in (That is how tight
of a fit this cooler is on the KT7 boards). The PEP66 shares
the copper base and anodized surface like the PAL6035, but the PEP66 utilizes a
fin structure rather than the pins like the PAL. Every time I look at this
cooler it reminds me of the great Alpha P3125 cooler that was the king for
cooling Slot 1 CPUs.
