Hello,

Thank you for reading.

Recently I updated the BIOS and iDRAC of the servers blade.

I updated the BIOS from 1.6.1 version to 2.5.4 and iDRAC from 1.35.35.00 to 2.30.30.30.

The problem is with the fans, because each 10 minutes the fans increase the speed and they are noise. I have 3 blade servers and 9 fans in this chassis.

I executed getsensorinfo in CMC

FanSpeed 1 Fan-1 OK 2874 rpm 1775 9034
FanSpeed 2 Fan-2 OK 3392 rpm 2107 9034
FanSpeed 3 Fan-3 OK 3400 rpm 2107 9034
FanSpeed 4 Fan-4 OK 2850 rpm 1775 9034
FanSpeed 5 Fan-5 OK 3398 rpm 2107 9034
FanSpeed 6 Fan-6 OK 3385 rpm 2107 9034
FanSpeed 7 Fan-7 OK 2865 rpm 1775 9034
FanSpeed 8 Fan-8 OK 3380 rpm 2107 9034
FanSpeed 9 Fan-9 OK 3384 rpm 2107 9034

Temp 1 Ambient_Temp OK 22 Celsius N/A 40

PWR 1 PS-1 Online OK
PWR 2 PS-2 Online OK
PWR 3 PS-3 Failed(No AC) Not OK
PWR 4 PS-4 Online OK
PWR 5 PS-5 Failed(No AC) Not OK
PWR 6 PS-6 Online OK

Cable 1 IO-Cable OK
Cable 2 FPC-Cable OK

Also, I executed the getfanreqinfo and I got this results:

[Ambient Temperature Fan Request %]
38

[Enhanced Cooling Mode]
Enhanced Cooling Mode(ECM) Status = Disabled.

The difference is with the fan request% of the third blade.

Can I change this value (Fan Request)?

What is the solution of this problem?

Thank you for your help.
