Hi. I've bought a DL180 G6 from eBay and have been really impressed with it EXCEPT for the fan noise. Reading a bit more can see that this is a tough issue to crack and the later versions (G8 / G9) have better fan control.
I tried messing about by fooling the fans into thinking there were 8 fitted and used wires to take signals from the other 4 (see the following link https://imgur.com/a/ydJaD#m3g4XSw ) and had success in dramtically lowering the noise but it did lead to the server shutting down randomly due to overheating.
I decided to put all 8 fans back in and test having 5,6 or 7 running and what volume of noise this would generate. During this testing a message popped up on one of the BIOS boots saying make sure non redundant fan cage in use and downgrading the BMC SDRR configuration from 2.17.1.208 to 2.17.1.203.
I was too slow to press the 'N' key and the downgrade occured. now only 4 fans are recognised and they run even louder (!) than the 8 fans previously.
My issue is that I want to use all 8 fans and go back to the updated BMC SDR Version 2.17.1.208. I've tried flashing the BIOS and ILO and also factory default BIOS and BMC using the jumpers but no luck.gratefully received
Any suggestions?
