Heatsinks for AMD socket c32

I have a super micro motherboard and an Opteron 4133 that I would like to use in a server, however heat sinks seem rare and expensive, anyone know if I can use the same heat sinks g34 or socket f? I really don't want to spend $35 on a passive heat sink I'll have to zip tie a fan to (tho if I could find one for <$10 I would)

Socket F heatsinks fit.

awesome, thanks man
