Fans not spinning all at the same speed

[Gerrietech]

Hi i currently own a hp proliant dl380p gen8 and everything works fine. I just have one problem and that is that fans 1, 2 and 3 are spinning at a low spead of 6% while fans 4, 5 and 6 sping at a speed fo 70% cause the server is hot. How do i make all fans spin at the same speed?

Connect to ILO and check the temperature map. A heated component may cause this.

Hello,

Hope this helps.

Please ensure all the blanks are installed

Get the below changes done in RBSU:
System Configuration > BIOS/Platform Configuration (RBSU) > Advanced Options > Fan and Thermal Options >Thermal Configuration>Optimal Cooling

Check the status now.

If it is already set to "Optimal Cooling" change the cooling mode to "Increased Cooling." and check for issue resolution.

>> If the issue persists, please perform a "cold boot" from iLO.

>> If issue persists,

shutdown the server
Drain the flea power by disconnecting any power input, all the external cables (including Power and Network), external devices and pressing and holding down the power button for 10 seconds.
Check the fans and be sure the air flows over the drive.
Reseat the fans. Also reseat any PCI cards if connected.

>> If the issue still persists, restore the server to system defaults.

Procedure

1.From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > SystemDefault Options > Restore Default System Settings.
2.Select Yes, restore the default settings.
3.Reboot the server.

>> If still same issue reduce the server to minimum configuration.
Remove all external PCI cards attached to server.
Start adding parts in incremental manner to isolate the faulty component.

Thanks.
