The unit comes with 7 honking screeching fans. All fans are connected by default, to cpufan1 port. Even with the screechers, and 22 disks, the inside case temp was getting to 47c, a bit warm
The schreechers were 6700 rpm, 84 cfm
So I removed again and replaced them with 5 different fans, so 2 fully pulled. Still loud, no temp change
I tried removing the 7 screechers, and replace with 4 0044l4 fans, but inside temp got to 56c, way too high, although system still marked that 'low'
So, next was those 3 0044L4 3600 rpm, 47cfm and 3 0104L4 2800 rpm,33cfm, not the 104l4 are in a green case, which will not fit in the sc847, I needed to put them in the screecher cases to fit. Pretty easy to do...
With this, the fans start at 2400 rpm, temp at 34c and slowly rises to 3600 rpm, case temp is 40c, and sound is down about half. The disks are at 42c. This is where it stays for days. I've enclosed my stats from IPMI monitoring. Got the disk temps from shell smartctl pgm
I think the 22 7200 rpm 4/6 tb drives is requiring the speed for temp reduction
Any ideas how to do betteron the sound?
