Arkua 838T-7G 2U Pentium 4 Heatsink Review
The 838T-7G heatsink from Arkua has
already made its way into more than a few Small
Form Factor PC's and desktops thanks to its small 2U stature, and easy
clipping system. The heatsink makes use of the existing Pentium 4 heatsink
retention mechanism and simply clips into place, with a small lever
to then put the core under tension and finish off the installation.
In those small
book-sized systems and SFF PC's space is at a premium, and so manufacturers have taken to using heat pipes, or hybrid heatsinks
like this unit from Arkua which are shorter than a typical P4 heatsink. Even
though the space may be small, the goals remain the same - good cooling
with little noise. Although the Arkua 838T-7G is not specifically designed
as a low-noise cooler, its 70mm fan is pretty easy on the ears.
Blessed with a very efficient fin design, and solid copper core, let's see
just how well this little heatsink performs!

The fan is mounted to a fan shroud which also serves duty as a heatsink retention mechanism. Behind the fan
motor is a small spring tensioned apparatus that extorts pressure
directly on the copper core of the heatsink. A small level on the side of
the heatsink makes it simple to engage and remove the heatsink for a standard socket 478
heatsink retention mechanism. The fan draws 0.28A and hooks up to a
standard motherboard power header.
Arkua have a good design on their hands, and in this
case it is only 23mm thick. At the heart of this
X-shaped heatsink is a 22mm wide cylinder of copper, the chewy copper insert is
there to help speed up thermal transfer and increase the overall effectiveness of the
heatsink. The fins measure 1.5mm on average, and are spaced a healthy 2mm apart. The
design is pretty classic, and can be very efficient with the right amount of
The Arkua heatsink is just 23mm thick, and with the height of the
fan apparatus should be just the right height to fit into a 2U server
chassis, small formfactor PC, or book sized computer.
There are no external clipping mechanisms on the heatsink,
and at about 200 grams, one of the lightest heatsinks we have
come across intended for use on the Pentium 4 processor.
The base is exactly like the top of the heatsink in
layout, but has been finished with a nice bit of machining so that it will
sit smoothly on the processors' heatspreader.
