DP55WB fan control issue at startup

Have a MicroCenter PowerSpec machine with DP55WB motherboard, Core I5 750 CPU, updated to BIOS v. 0165.  If the machine has been left unplugged for a day or two, when it is turned on, the CPU and system fans run at full speed and are noisy.  This is despite the fact that the fan control is enabled in the BIOS.

 

Simply telling Win 7 to restart corrects the problem.  As the machine reboots, the fans settle down to controlled speeds (i.e., 1200 RPM or so).  Further powerdowns and powerups do not then exhibit this fan control problem, unless the machine is unplugged for a few days.

 

Anyone else have this problem?
