Arkua 848X-6B 1U Pentium 4 Heatsink Review
When was the last time you said to yourself "I need a 1U heatsink for my Pentium 4
server" and came up empty? Well, this week we are examining a few
1U and 2U heatsinks for the socket 478 form factor. These heatsinks are
being manufactured with the intention that they will be used
to cool down server chips, but in this day and age it seems
more likely that these active heatsinks will get mounted into a Small
Form Factor PC. After all, those types of computers are steadily
gaining in popularity as Shuttle's online review presence steadily promotes their virtues.
In those small aluminum cases, space is
at a premium just as it is in servers. The goal in each instance
is to optimize the thermal performance of the heatsink. In the 1U server, the
heatsinks get a helping hand from the case fans which can
range anywhere from four squirrel cages blowers, to a series of 40mm "stubbies."
Putting that aside, one thing
is immediately evident about the Arkua 848x-6B heatsink - it's based on a very
efficient fin design, and with a solid copper core at its heart it will surely
be interesting to see how it performs!
Give the size
constraints the Arkua 848X-6B is up against, it is little wonder that the
heatsink makes use of a back plane connector plate. Not only does the metal
bracket support the PCB against any mounting stresses, but it also forms the
basis for mounting the heatsink. Four screws lock into the four posts and an
integrated spring system on
the heatsink applies the tension.
All in all, the system is remarkably
easy to use, but the motherboard will have to be removed in order to install the
heatsink - there is no way around that.
