Strange cooling fan noise - Video

Does anyone else have a strange grunting noise when the fan first spins up? I bought a used fan and installed it today and both my old fan and the replacement make the same noise. I could just have got unlucky twice, but that seems unlikely. On hot days inside the car it sounds like someone farting in a bathtub when it spins up.
