Workstation System P4000CR
3.3.1 Fan and HDD Configuration
The Intel
®
Workstation System P4000CR consists two 120x38mm system fans and two active
cpu heatsinks providing cooling for all ingredients inside the enclosure. The two 120x38mm
fans deliver different cooling capability and are not interchangeable.
The active cpu heatsink fan has Performance [P] and Quiet [Q] mode switch on the top of the
fan frame. And it is required to keep the switch at Performance state to provide sufficient
cooling for cpu and best system level acoustic experience.
All the fans are Pulse Width Modulated (PWM) 4 wire/pin fans. The fan headers are connected
to motherboard with below sequence. Misconnect will potentially lead to thermal risk or
undesired acoustic.
 SYS FAN 1 connect to PCI fan
 SYS FAN 2 connect to Core fan
 SYS FAN 3 reserved
 SYS FAN 4 reserved
 SYS FAN 5 reserved
 SYS FAN 6 reserved
 CPU 1 FAN connect to processor 1 active heatsink fan
 CPU 2 FAN connect to processor 2 active heatsink fan
 REAR FAN reserved
The Intel
®
Workstation System P4000CR supports up to four fixed HDD. It is required the four
HDDs are installed evenly to prevent HDD overheat and best acoustic experience.
Figure 32. P4000CR System Overview for Thermal Management
Note: If Quiet Fan Idle Mode is enabled, with combination of Altitude set to [300m or less] or
[301m-900m] and Fan Profile set to [Acoustic] mode, the core fan will stop running when the
aggregate sensor temperatures are satisfied indicating the system is at good thermal/light
loading conditions. For other scenarios, the core fan will maintain a minimum RPM.
