We've recently purchased as used HP DL580 G7, and we noticed within a few hours of hookup that the fans were ramping up very high. I then proceeded to configure the iLO 3 to see what was causing the fan ramp, but the only temp sensor which reads high (within 10 degrees C of 'Caution'- item is ~50C, Caution @ 60C) is "Temp 20". There's nothing in any of the documentations I've found on Google, or forums anywhere which will tell me where this sensor is.
I have tried updating the firmware on the iLO 3 to the latest (1.90), however it only seems to quiet the fans down for a few hours. All of the other temps are well within norms, with a very large headroom before approaching their 'Caution' temp.
Would anyone happen to now which part/location on the server is "Temp 20"? Thanks! The fans will only ramp up when "Temp 20" is
