GlacialTech manufacture inexpensive OEM class heatsinks of a fairly standard design, although they add a few things to make them stand out on the shelf. There are no special fin designs, exotic materials or turbine fans, but there is a stiff clip and a red anodized fan shroud. The simple aluminum extrusion and fan are complimented by a extra shiny plated heatsink finish and pre-applied patch of silver-based thermal compound.

For starters I'd have to say that the clip on the Igloo 2400 is the stiffest I've ever seen on a heatsink. While it is good that a stiff clip will ensure that a heatsink is properly mounted on the processor core, it can also lead to chipped core edges, or even broken processors of the force is too great.

Socket clips like this seriously make us investigate adding some digital force gauges to the FrostyTech set of heatsink test equipment. The only really problem is that load cells cost and arm and a leg, and Amtek or Chatillon digital force meters are just about as expensive.
