Third-party utilities won't work - they need to know how to talk to and query the BMC/ESM.  You need OpenManage Server Administrator (OMSA): [URL] Download and run to extract the files, then run C:\Openmanage\windows\setup.exe.  Choose Custom and make sure that Storage Management is installed (leave ALL else as default).  Add servername:1311 or ipaddress:1311 to Intranet Zone in IE.  May require a reboot to access OMSA.  Then look under System, Main System Chassis, Fans, Temperatures, etc.
