The bundled Laminar RM1 cooler is at least serviceable, though we always recommend buying a better cooler. The stock cooler isn't silent, so you'll have to accept the extra noise. The bundled cooler is good enough to handle the chip at the lower 65W/148W power limits and adequate for multi-threaded workloads with the power limits removed. You could see some performance impact with higher ambient temperatures or longer-duration workloads, so opting for a lower-end air or water cooler could improve performance in long-duration work.
