Cooler Master Hyper 612 Ver.2 is an outsider. The largely ignored CPU cooler is now available for $38, making it one of the most affordable heat sink for passive cooling.
The Hyper 612 Ver.2 is 732g and features six 6mm direct-touch heat pipes. No mention of any TDP limit on its official page, so proceed with caution and opt for sub-65W processors.
