Noctua NH-U12A
The NH-U12A packs 140mm-class cooling into a 120mm footprint with zero RAM overhang (pro tier), making it the compatibility-safe premium air pick for tight builds and tall-memory layouts on AM4, AM5, LGA1700, and LGA1851. At 158mm it still needs a clearance check. Value hunters and anyone after RGB will balk at the price and the beige/brown fans.
