Hey guys - I have a Supermicro SC846 chassis running dual E5-2670s, 256GB of RAM, 16 x 8TB disks, and 8 x Intel S3710 400GB SSDs. It's an ESXi box for my lab. I am using Noctua NH-U9DX i4 on each CPU. I was up around 75 - 80% RAM utilization and started getting a "high non-critical" (80C) alarm on a DIMM or two. I had swapped in some desktop, lower speed fans into the chassis fan holders because the server was in a spare bedroom and I didn't want to hear the noise so bad.
Now the server is in the basement which is a constant 72 - 74F and so I put the original fans back in. The noise is not very noticeable with the standard or optimal fan profile. However, I've got a couple hardware status alarms so far for CPU fans because the Noctua NH-U9DX i4 fans are so slow - 600RPM, which triggers an IPMI alarm. I could modify the alarm to be around 500RPM (should never really hit that) but the reality is, I wouldn't mind some faster CPU fans since the unit is now in the basement.
Can anyone recommend a 92mm fan that would still be PWM but spin faster at lower PWM%?
Thanks!
