I'm doing my first build and to start I'm using the infamous stock Intel HSF that came with the E8400. It's going on a Gigabyte EP45-UD3P. I'm not intending to overclock, and I apologize if there's a better forum.
It's a matter of experience. I can't tell if I've got the last pin in far enough. On three of the pins, when viewed from below the MOBO, the black male pin (inner) is just about at the same depth as the white female (outer) part of the pin assembly. On the fourth pin, the end of the black pin is up about 1/16 of an inch from the end of the white pin. All of the pins feel quite secure.
I've used a lot of force (with the board out, and supported) and this seems to be as good as it gets.
Am I there yet?
