I think the fan you are refering to is the Northbridge fan.  I would
not recommend removing either on the fans.  Try undervolting the CPU
fan after you underclock the cpu, be sure to monitor the CPU temp
under sustained load.  Even at relatively low fan speed, you will
still need a fan to move the air through the case.
