Scythe Kozuti SCKZT-1000 1.5U Low Profile Heatsink Review
 

The Scythe Kozuti SCKZT-1000 is a really compact low profile heatsink that conforms to the 1.5U standard and measures just 40mm from tip to toe! That's not a lot of space in which to cram a heatsink capable of handling 150W heat loads... but Scythe manage it with average thermal results - impressive for such a low profile heatsink really.
