P4DC6 heatsink suggestion

Hi, Recently i managed to get my hands on a 2.4Ghz xeon processor to
fill my second cpu slot on my P4DC6 mb.

Only; I seem to have misplaced my second heatsink and cannot use the
processor until i find a new heatsink. So before i go shop for a new
heatsink i thought i'd ask for advice on which one i should choose. A
low noise modest one is on the top of my list

Thanks.
