Have the same issue? Flashed it to the newest Version; and fans will run at intermediate speed for about 10 hours, get message of temperature differential and fans set to high speed. RWC2 shows temps between 17 and 20 degrees C. Have 8 drives installed and the blanks are in the other cages. Seems the only way to get it quiet is complete shutdown, and then it will run at an acceptable noise level for 10 to 12 hours.
