Lasagna BGA cooler
Overclocking is approaching the level of a fine art. No longer is it simply a
matter of influencing the main processor to perform leaps ahead of its intended
speed. No, now we begin to tinker with the effects that memory, motherboard, and
other components - nay, even sub-components - have on our ability to yank ever
more performance from that small slab of silicon.
One such component is in the form of a BGA chipset at the very base of the
processor slot on the motherboard. Routinely these chipsets come with a lame
green heatsink, which, more often then not, forgoes even a trace of thermal
compound in its interface. Stuck with OEM's cramming lack-luster cooling
solutions down our throat, a few alternatives have surfaced. With the steady
increases in power, speed and worst of all heat coming from silicon valley this
is a welcome sight.
The mildly expensive Lasagna BGA cooler is one such device, and one we were
able to test out recently. The $19 US price tag leaves one looking desperately in
search of an OEM who makes the things, and hopefully sells them at a better
price. But no such luck.
What you get for you hard earned cash is at least satisfyingly better then buying
a GFD these days. The cooler, some thermal compound, printed instructions (gasp!)
and even extra pins in our case. Did I mention those instructions actually
have words on them - Leufken take note! The unit is a well made sandwich
of stamped out aluminum which has been riveted together to form a grill
of sorts around a small fan. For the power hungry out there, the Lasagna even
comes with a pass-through Molex power connector.
The premise of the device is this, passive heatsinks work by radiating their
absorbed thermal energy to the surrounding air. Active heatsinks seek to improve
on this convection cooling method by forcing more air over the heatsink
material, hence increasing the amount of thermal energy removed. Spiffy active
heatsinks try various methods to get the air being moved by the fan to do as
much cooling work as possible. The Lasagna is one such attempt...
