I just installed the latest iDRAC6 firmware (1.50 A02) upgrade for a Dell PE R210 in a hope to reduce the noise levels of the fans as per the BMC fixes (1.50 A04) but the fans are still running fairly high.

With the previous iDRAC6 firmware (1.30) the fans would run at 8500 rpm way too loud and even changing the BIOS power settings made no difference. Now with this release the fan speeds went down initially to around 6500 rpm and are now about 7020 - 7200 rpm. I have changed the power settings for minimum but this has not really made a lot of difference. Does anyone know of how to get the fan speed down further to say 4000 - 5000 rpm? I know the internal components have to be cooled but even the Dell PE R610 which has more fans and components runs more silently.

The server does have the PERC H200 adaptor card installed along with the iDRAC6 Enterprise card and two hard drives and the board temperature is around 28 - 30 Centigrade.

Any help would be appreciated.
