The Scythe Katana II
heatsink boasts four rather unique technologies to its name; OFCS, VFMS,
wide range RPM, and four way mounting. The first of these acronyms essentially
describes how the copper heat pipe comes in contact with the aluminum fins of
Oval Fin Contact
Structure (OFCS) increases the surface area between the aluminum fins and
heat pipes by a small degree, which apparently improves heat transfer.
Additionally, the slanted orientation of the fins reduces the overall volume
of the heatsink,
and works to direct exhaust
airflow down towards adjacent motherboard components.
