 Datasheet

The boxed processor fan will operate at different speeds over a short range of internal chassis 
temperatures. This allows the processor fan to operate at a lower speed and noise level while 
internal chassis temperatures are low. If internal chassis temperature increases beyond a lower set 
point, the fan speed will rise linearly with the internal temperature until the higher set point is 
reached. At that point, the fan speed is at its maximum. As fan speed increases, so does fan noise 
levels. Systems should be designed to provide adequate air around the boxed processor fan 
heatsink that remains below the lower set point. These set points, represented in 

 and 

, can vary by a few degrees from fan heatsink to fan heatsink. The internal chassis 

temperature should be kept below 40 ºC. Meeting the processor’s temperature specification 
(see 

) is the responsibility of the system integrator.

The motherboard must supply a constant +12 V to the processor’s power header to ensure proper 
operation of the variable speed fan for the boxed processor.
