    System fan speed control on current Intel boards??


      I have the DG43GT desktop board & have noticed that my (2) system fan speeds never seem to change. Even when loading the system under Prime95, I see my cpu temps climb to 75C & that has me wondering. There is no temperature threshhold adjustment in the BIOS, so how is the fan control  supposed to function?  I have 2 system fans that spinning @ 700 rpm, but the are rated at 1900 RPM @12 volts. Obviously the board is slowing these fans down by dropping the voltage?? Could it be that I need to have case fans that have RPM sensing for the system fan control to function properly ??
