After my wonderfull KT3-Ultra ARU Raid board went bad, and upgrading to the KT4 ultra board, I noticed that my Zalman 6000 (I think) heat sink would no longer be able to be used. This is because that heatsink requires mounting holes around the CPU. I searched everywhere for an MSI or ASUS board with those holes, to no avail. I had to downgrade to the Volcano7! I LOVED that zalman fan, it was quite, and cooled to the max. Anybody know why none of the newer motherboards have those mounting holes? I'd think more would, considering it takes stress off the CPU.
