Troubleshooting cooling problems
CAUTION: Many repairs may only be done by a certified service technician. You should only
perform troubleshooting and simple repairs as authorized in your product documentation, or as
directed by the online or telephone service and support team. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow the safety instructions
that came with the product.
Ensure that the following conditions exist:
• System cover, cooling shroud, PCIe shroud, GPU blanks, PSU blank in PSU slot 2 if hard drive cage is
not installed, uSATA SSD blanks if uSATA SSDs are not installed, memory module blank, or back-filler
bracket is not removed.
• External airflow is not obstructed.
• A cooling fan is not removed or has not failed.
• The expansion card installation guidelines have been followed.
• Ambient air temperature is 25°C or less depending on the system configuration.
Additional cooling can be added by using one of the following methods:
From the iDRAC Web GUI
1. Click Hardware → Fans → Setup.
2. From the Fan Speed Offset drop-down list, select the cooling level needed, or set the minimum fan
speed to a custom value.
From F2 System Setup
1. Select iDRAC Settings → Thermal, and set a higher fan speed from the fan speed offset or minimum
fan speed.
From RACADM commands
1. Run the command racadm help system.thermalsettings
