Ryzen 7 2700x / MSI x470 Gaming Pro - No Post, Fan Not Started

  • Motherboard: MSI X470 Gaming Pro
  • CPU: AMD Ryzen 7 2700X with Wraith Prism LED
  • Power: EVGA SuperNOVA 750 G2


Should the fan that came with the AMD Ryzen 7 turn on during boot sequence?


First time build.  The PC is not posting.  Noticed that the EZ Debug LEDs on the motherboard for the CPU come on and after a moment turns off.  From MSI troubleshooting site that seems to suggest success but fan does not turn on.  The Memory LED does not turn on either.  I'm not sure if the CPU, Fan, or Memory is at issue and trying to debug but first question was whether the fan not turning on is an indicator of an issue with CPU install.  It appears to be seated properly with power connected for the CPU fan.


Amazon reviewer suggested fan is not supposed to turn on.  Tom's Hardware forum suggested it should (though were different components).  Looking for any clarity on fan behavior I should expect.
