IBM PC300PL / Netfinity 3000 - Fan speed varies or stops/starts
Applicable to: World-Wide
Users may become aware that during the normal operation of IBM PC300PL Series 6862/6892 systems that the cooling fans may either vary their speed (RPM), or stop and restart automatically.
This tip also applies to Netfinity 3000 Type 8476 systems.
The following text, "System-Management Controller" (p. 44) is found in the "Using Your Personal Computer" booklet included with each system and addresses this feature:
SYSTEM-MANAGEMENT CONTROLLER
Note: The following information is for some PC300PL only.
Your computer is equipped with a system-management controller (LM80) integrated with the system board. This controller provides hardware monitoring for system-board temperatures, fan speed, power supply and processor voltages, and the detection of the removal of the computer cover (see Chassis-Intrusion Detector).
Used with the DMI BIOS of the computer, the system-monitor controller can also store the hardware test results from the power-on self-test (POST)."
End users, support personnel, and servicers should be aware that this is a normal operating feature of the system and does not indicate a hardware malfunction.
NOTE: The cooling fan contained in the power supply is a variable 2-speed fan and should always be in operation.
