Dell PowerEdge's can be very loud especially if they are right beside you. However their fans can also be controlled. They have something called IPMITool that allows you to send the idrac commands of certain things you need. In this case its about the fans.
To control the fans you need to make sure that your computer has ipmitools installed. Once done, now you need to get your command prompt ready. That means when you open it, you cd to where ipmitool has been installed. Below will show what this looks like.
1: In Command Prompt: cd "directory of where ipmitools is"
Ex: In Command Prompt: cd "C:\Program Files (x86)\Dell\SysMgt\bmc"
Now since that is set, you can run commands.
For Sensor readings you would input: ipmitool -I lanplus -H [interface] -U [username] -P [password] sdr list full
For fan control you first have to enable manual control by:
Enable manual/static fan control: ipmitool -I lanplus -H [interface] -U [username] -P [password] raw 0x30 0x30 0x01 0x00
Finally to set speeds this is done by:
Enable manual/static fan control: ipmitool -I lanplus -H [interface] -U [username] -P [password] raw 0x30 0x30 0x02 0xff 0x(Some Integer)
The reason for some integer is cause that part controls the speed. 2 examples are:
Set fan speed to 20%:
Enable manual/static fan control: ipmitool -I lanplus -H [interface] -U [username] -P [password] raw 0x30 0x30 0x02 0xff 0x14
Set fan speed to 10%:
Enable manual/static fan control: ipmitool -I lanplus -H [interface] -U [username] -P [password] raw 0x30 0x30 0x02 0xff 0xa
Note:
Replace [interface] with your iDRAC IP address
Replace [username] with iDRAC admin user
Replace [password] with iDRAC admin password
