In reviewing so many heatsinks we get to notice the little short cuts that manufacturers sometimes take to get the most out of one design. These short cuts aren't necessarily a bad thing, but the do give us a bit of insight into what goes on behind the scenes in a way. Take for example the Glacialtech Igloo 3300 socket 478 heatsink shown below. If you've been following FrostyTech for a while you might think you recognize this very same heatsink as the Igloo 2400. Well, you are partly right.

The Igloo 3300 comes with a slightly off center fan on the fan shroud and a small patch of silver based thermal compound pre applied to the base. On other Glacialtech heatsinks the offset fan looked like it was done for thermal advantages, but with the 3300 it looks as though this is only the case to fit in the manufacturers stamp along one side.
