    Checking System Cooling Fan Operation

    GForce

      We replaced our D875PBZ system board with another of the same model, so we were sure that all the old hardwaere would be compatable. We've gone into CMOS and told it to disable "System Fan" in the setup. Even after doing this, the system will not boot giving the following message.

       

      ***********************************

      Checking system cooling fan operation:

       

      The system's cooling fan is not operating properly.

      Please check fan operation.

       

      Your system has been halted.

      ***************************************

      The fans are all working properly. Before turning off that notice in CMOS, the case fan would stop just prior to that screen message. After disabling that in CMOS, the case fan stays on but the message still shows. No beep codes, no nothing. The only thing we can do is reboot, and the message shows again.

       

      Hope someone can steer me in the right direction.

       

      Thanks.

          The Intel(R) Desktop Board technical support available would be at the following site: http://www.intel.com/p/en_US/support/highlights/dsktpboards/d875pbz
          If the system fan is disabled, the system will never boot. Disabling the system fan is basically instructing the fan not to spin.
          Due to this, first thing you may want to do is try restoring BIOS to default settings. Try changing the configuration jumper to its opposite possition (2-3) in order to boot directly into the BIOS, press F9 to load defaults, save changes and exit.
          If this does not work, please feel free to review the Main Product Support site for more troubleshooting options.
