The Enzotech SLF-1 Forged Copper Northbridge/Southbridge Low-Profile Heatsink features a mirror-finished heatsink, a forged copper pin structure and a very low-profile design at a mere 13.5 mm! Designed with compact motherboards in mind, the low height makes it much easier to mount - and avoids interference with SLI or Crossfire systems. The mirrored-finish ensures perfect thermal conductivity between the processor and the heatsink and the all copper design lets the Enzotech SLF-1 cool amazingly well!
