Reviews of Scythe cooling products always seem to require commentary on their uniqueness. The FCS-50 is no exception. This heatsink fan is a canny mix of the TS Heatronic patented flat heatpipe technology with flow-through forced air cooling and a versatile mounting system that's compatible with every type of desktop CPU currently sold.

At a quick glance, the FCS-50 shares some obvious characteristics with the new rash of tower style heatsinks:

  • It's tall rather than wide.
  • It's big.
  • The fan is mounted sideways and blows across the HS rather than down from the top.

As you will see, there are many differences that mark the FCS-50 as distinct from the rest of the tall blow-through HSF crowd. One of the claims made is that this product satisfies the needs of both performance overclockers and quiet PC enthusiasts by means of a fan whose noise / speed can be varied from a maximum of 46.1dB @ 4600rpm to a minimum of 15.1 dB @ 1300rpm. That is certainly an enormous range, considerably wider than with most fans and speed controllers we've seen
