Honestly, unless you plan on overclocking above 4.0GHz you should be fine with the stock Intel HS/F.
If you want one regardless, check out the Noctua NH-D14
Its a little more than the Frio, but one of the best (if not the best) air coolers available.
I'd have to assume it would fit your motherboard since the P8P67 and P8Z68 Deluxe models look like they have the same layout, and Slaymate is currently using one.
