The Aftermath:
The CEP426152 provides a decent cooling solution as an upgrade from the already competent stock Intel HSF. The cooler fits nicely atop the CPU socket and the clamps are placed safely up and away from my Gigabyte motherboard's capacitors. Another nice thing I've noticed about this cooler is the fact that the actual positioning of the CPU on the heatsink is almost dead on centered (see picture of the CPu imprint in thermal compound).
