The $16 dual-tower

In a world of $100 CPU coolers, this $16 unit is an attractive option. Semoic is actually a well-established brand in China, manufacturing mostly motherboards.

Featuring six 6mm heat pipes this dual-tower is compatible with all sockets, and should perform well paired with the 35W Athlon 3000G, including in passive mode. Please note that this heat sink is only 135mm high though (flagship products from Noctua, bequiet, or Phanteks are generally 160mm high).
