Hello The iDRAC creates a thermal profile based on installed hardware. If you install hardware that it does not recognize then it will assume a high thermal output for the device. The fan speed response is adjusted based on the thermal profile. We do not provide an option to decrease fan speeds. We do provide options in most of our servers to increase fan speeds. So, the more hardware you add the higher the minimum fan speed will be. If you install unsupported hardware the minimum fan speed may be further increased. [URL] Thanks
A R420 at a customer is running with fan speeds of 6000 ups. This makes it unacceptably loud for the people that are sitting in the same room. Other R420 at other customers in comparable environments are running with fan speeds between 2800 and 4100 ups. The loud R420 is fully patched (iDRAC 2.60.60.60, BIOS 2.6.0) and is running with non-DELL ("certified:no") HDDs. Some of the other R420 are also running with non-DELL HDDs, but they are running various older iDRAC/BIOS versions. I tried to slow down the fans by changing some parameters (ThermalProfile, FanSpeedOffset, ...) with racadm but with no avail. There is no PCI card installed, the CPU is idle and the "System Board Inlet Temp" is 23°C. I read in forum postings somewhere that current iDRAC/BIOS versions speed up the fans when non-DELL HDDs are detected. Is that true? Any idea what I could do to slow down the fans in this R200? Thanks,Florian
R420 too loud - reason non-DELL HDDs?
