    91 cooling fans the tdz 2000 has three cooling fans. One is inside the power supply; the others are mounted in the chassis. All fans are 12 vdc. The fans pressurize the chassis and force warm air out from the vents. Hardware controls the dynamic speed of each four-wire fan. See chapter 5, “system bo...
