Disclosed are a centrifugal fan blade assembly and a centrifugal fan, comprising a plurality of blades, a blade leading edge of at least some of the blades being provided with an interference groove, the interference groove extending in a width direction of the blade. By providing the interference groove extending in the width direction of the blade on the blade leading edge, when the fan blade assembly is running, the interference groove changes noise frequency, thereby preventing the blade leading edge from producing a relatively large broadband noise after being impacted by a high speed air flow, thus effectively reducing noise.
