Steps to fix speed issues by applying a BIOS default setting.
The system fans started running too fast after a firmware update.
Latest BIOS version was installed, but the issue persisted.
Apply BIOS default settings to resolve fan speed issues when it's a brand new system.
1. Power down the server and unplug the power cord(s).
2. Remove the system top cover and move the BIOS DFLT/J2B1 jumper from pins 1 - 2 (default) to pins 2 - 3.
(Set BIOS Defaults)
3. Wait 5 seconds then move the jumper back to pins 1 - 2.
4. Re-install the system top cover.
5. Re-Install system power cords.
6. During POST, access the BIOS Setup utility to configure and save desired BIOS options.
