I wasn't planning to make any significant changes to
the computer components themselves, except for the longer data cables
required to stretch around such a large case, but somehow this still
left me with a huge shopping list of fans, lights, water cooling oddments,
mounting brackets and who knew what else! As usual, most of what I need
for my PCs is rare enough that I have to import from the US, but the weak
dollar was again my friend and it didn't cost more than the customary couple
of limbs.
The Koolance subsystem has its own built-in thermal
management, but I wanted to retain a level of manual control over the two
case fans and had already decided to ditch the DigiDoc fan
controller in favour of something simpler. This removed a significant
quantity of internal cabling right away, and I have to admit that the
build was considerably easier without the requirement of incorporating something
resembling an angry squid into the cable management scheme.
I've been aware of the
mCubed T-Balancer
USB sensor hub since its launch last year, and it's such a neat little
gadget that I really wanted to build it into the new chassis.
However, it soon became clear that even the two 120mm fans fitted to the
stock PC-V2000 were going to be mostly cosmetic, and long experience with
various models of DigiDoc has shown that not only do you rarely need to
know the exact temperature of eight locations inside a PC, but that when you
do know you just start worrying about it... Even though the
T-Balancer has all sorts of nifty add-ons to allow monitoring of
temperature and rate of flow in a water cooling system, it seemed like
overkill to install something so complicated when for what I actually
needed a simple knob would do almost as well. The old version of the
PC was a bitch to work on inside because of the complexity of fan and thermal
monitoring busses, and I really wanted to keep things a little more slim
and elegant - especially with the unknown factor of the water cooling
hoses to install. |

I was hoping that the Swiss cheese design of the Lian
Li case, together with the motion of air caused by the two 120mm fans
above the radiator at the top of the case, would be enough to keep the few passively cooled
components quite happy, but old habits die hard... I really wanted a pair of blue illuminated fans to
replace the undistinguished units that shipped with the case, and the new
Aerocool Turbines were just too pretty to pass up. As case fans go
their specifications are actually rather uninspiring (most 80mm fans could
match their lackadaisical 37 CFM air flow) but because of this they are
extremely quiet at less than 20dBA - and after the roaring wind tunnel
ambience of my previous PCs I was determined that if I was going to use a
fan mostly for its cosmetic appearance then it had better be quiet!
Aside from their unusual black and chrome colour
schemes, the Turbines are sold mostly on the dubious distinction of having
"more fan blades then any other 12cm fans in the market!" -
but as
anyone who has paid even minimal attention to the wonderful and perplexing
science of turbulence knows, this is not necessarily a good thing when it
comes to providing a smooth flow of air. In the event, however, they are completely inaudible
even when cranked up to their lazy maximum of 950 rpm, and the subtle blue
glow from the LEDs works extremely well - as well as lighting the mirror
finish blades themselves, the rear fan beautifully highlights the cooling
pipes arching over the CPU water blocks, and the other glows eerily
through the mesh front panel. |

I've attached both fans to a
Vantec Nexus
NXP-305, a neat little 3½" device that controls three fan channels and
the pair of 12" blue cold cathode lights that ship with it - and, of
course, the transparent rings around the control knobs are illuminated to
provide its own blue glow. I installed the long cathodes vertically on
either side of the the 5¼" device bays, where they shine clearly through
the perforations, and between the various light sources I have an even
illumination for the full height of the front bezel - the large blue and
red Koolance status display right at the top, the vertical CC tubes
flanking the device bays, then the Nexus, and finally the Turbine fan down
in the bottom third. The effect is everything I'd hoped for. |

The unused third fan channel has actually been co-opted
to drive a pair of 4" AC Ryan cold cathode tubes, and although I was a
touch dubious at the idea of connecting the inverter to a variable
voltage, I assumed that the dedicated lighting channel actually worked in
just the same way and decided to take the chance. In fact it seems to work
perfectly, adjusting the light level from off to dazzlingly bright,
apparently in little jumps - presumably some side effect of the inverter's
electronics. I've placed the two little tubes in positions where they
throw light on the front part of the motherboard, balancing the light from
the Turbine fan at the rear, and between them the interior of the upper
part of the case is brightly and fairly even lit. The effect in daylight
is restrained, but in the evenings with the room lights down low the PC
can be switched from a subtle glow to something reminiscent of a 1950s
jukebox. |

During the build of Infinity3
I spent many hours patiently sleeving dozens of cables ranging from the
thermal sensors feeding the DigiDoc to the power supply leads, the latter
requiring some extremely fiddly work with a full set of Molex pin removal
tools and much muttering and cursing under the breath. This year, however,
braided cables have become a standard feature rather than an exotic
luxury, and companies such as
Performance-PCs (motto: "Sleeve it and they will come") and
FrozenCPU are providing pretty much
anything you can care to name pre-sleeved off the shelf. Some are made
that way, such as these IDE and floppy cables from Antec... Others, such
as power supplies, are modified in-house, and for the nominal fee they
charge this service is definitely worth it. Now
on to the wet parts of the project... |
