As a general rule, Intel's heatsink and matching fan are
quite adequate, from an engineering point of view.
It's the stupid push-pins that Intel should have abandoned
many years ago.
The bolt-thru kit above should work fine; just remember
to install it and the CPU before installing the motherboard
in your chassis.
UPDATE: oops! my mistake: apparently there is a new
HSF for that CPU. See photos here:http://www.legitreviews.com/article/1245/2/
So, Intel finally has done away with their stupid push-pins,
at least on this model CPU.
Nice video here with instructions for installing this new HSF:http://www.youtube.com/watch?v=_x_vhZNAGSw&feature=player_embedded
