I was about to buy 3 of the 140mm heatsinks but $20 to ship 3 heatsinks is a bit much IMO.

I think I will just go with arctic alpine 11 plus CPU heatsinks as I have used in past for $10 (edit now $12.50), so ~half cost before shipping. Wanted to try these but cannot justify spending $80 on three heatsinks.
