Another Dell IPMI Fan Control Script, 5 settings, both ESXI and Linux hosts Service scritps for either systemd or SysV

          Please go to intel ARK for your CPU and check the 

          TDP (Thermal Design Power) 

          then subtract about 20-10 degrees C for returntoauto

          this allows the BIOS to manage high temps

          tested on R630 with e5-2697a V4

          Monitor the temps and speeds to fine tune your system

          on systemd just use journalctl -t fanctl to see what temp changes are triggered
