RX300 S7 Low Noise Mode

Postby outlander » Sat Mar 16, 2019 13:08


I have bought a RX300 S7 and the server is in a separate room. Nevertheless the server is too noisy.

For some reason I am not able to enable the LNM in BIOS.

I know the limitations for LNM
only 1 DIMM per channel -> OK
CPU max 80W -> 2 x 11W OK
only PCIe 7 RAID -> OK
ambient temp < 25 -> 18 OK

BUT LNM is not activated.

One of the fans is spinning at 200% !?!?

I had this problem so I removed the fans and heatsinks. replaced with artic freezer coolers. Got some patch jumper cables and connected the fans to the fujitsu connectors. Now its whisper quiet. You have to leave the lid off.
