I have  Intel 750 ssd and if I put it in server works normaly.

I ran these commands:

ipmitool.exe -I lanplus -U root -P calvin -H 192.168.192.168 raw 0x30 0x30 0x01 0x00

ipmitool.exe -I lanplus -U root -P calvin -H 192.168.192.168 raw 0x30 0x30 0x02 0xff 0x46

But I get error:

Error: Unable to establish IPMI v2 / RMCP+ session
Unable to send RAW command (channel=0x0 netfn=0x30 lun=0x0 cmd=0x30)

I managed to run these commands but nothing has changed, fans still run at 85%. Maybe I am using bad raw command if so can you give me correct one?

Command that you gave did not solve the problem, system fan still runs at 85% speed. Syestem uses 4 ram slots(4x16GB), 2 cpu slots, 2 hdd slots, 2 pcie slots.

I have bmc  utility instaled on my windows machine. I  can connect  to  server. I used thread  to check status

"and here is the command to check the status.

raw 0x30 0xce 0x01 0x16 0x05 0x00 0x00 0x00"

I  get 16 05 00 00 00 05 00 01 00 00

I spotted one thing. When i run bmc comand

ipmitool -I lanplus -H 192.168.192.168 -U root -P calvin raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00

On iDrac I can see that fan rmp changed from 10080 to 4200, but fans spin at the same speed (85%). Is that raw command universal, if no then maybe I need another command?

Fan noise, nor speed have not changed,  just numbers that  idrac shows are lower. I applied bios 2.2.5  and  idrac 2.30.30 updates. Maybe I have faulty fan or motherboard? Temps are max 42 C.

But why it behaves normaly with pcie Intel 750 SSD. I do not think that fan is faulty.

I  tried new fan,  still same happens
