Four of these fans are on the processor cooler (heat sink). These fans are controlled by the motherboard on which they are housed (i.e. as the processor temperature increases, so does the fan speed).
  
-There are two large fans on the bottom of the case. These fans pull air from underneath the case and push it into the three worker blades. The fans, using a "Y" splitter, are attached to an auxiliary fan port on the main motherboard. A monitoring daemon running the main motherboards checks the processor temperature of each blade and reports the highest temperature to a second fan control daemon that controls the auxiliary fan port. If any blade temperature increases, the bottom intake fan speed is increased. +There are two large fans on the bottom of the case.

 The remaining fan is on the back of the case and runs at constant speed. This fan is used to help move air through the case. The remaining fan is on the back of the case and runs at constant speed. This fan is used to help move air through the case.
