I've got an older i5-3570K running Truenas. A fan began making loud buzzing, so I replaced it with cheaper ones. Unfortunately, more fans are now active and audible (previously silent except for the one that would start rattling). Truenas doesn't support native fan control, and my research suggests many options exist if I have a server-grade board. Since I don’t have IPMI and have an old 3rd gen desktop, connecting it to a monitor might let me adjust BIOS fan curves, though I’m unsure if the changes would be permanent. I discovered a project at GitHub that lets you control fans via Docker, but the example paths don’t match Truenas, so I’m not sure how to proceed. My goal is to run a Docker script as a custom application, and I also saw another project at GitHub that could work in a VM.

Your board allows fan management through its interface—most models offer a quiet mode setting. TrueNAS doesn’t adjust fan speeds directly, as it’s designed to run quietly.

You mentioned that TrueNAS won't interfere with what you configure in the BIOS. I only use the BIOS to manage my fans. Are you certain it's just the fans making noise, or could something else be vibrating? It took me longer than I thought to identify the source of the sound on your son's PC. Placing a hand on the case would silence the noise. In the end, the vibration noise was coming from the PSU filter at the bottom being shaken. I removed it, bent it slightly, and the case has been quiet ever since.

They were former supporters, the file was a free sample from work. The newer supporters aren't reacting as strongly, they just seem like enthusiastic fans. @AbydosOne Should you force it and connect it to a monitor and keyboard?

It seems it’s time to purchase some budget fans. It feels counterintuitive, but I usually stick with Noctua for my other gear. The NAS got affordable fans recently. I discovered a set of Antec or Artic fans in packs of five and ordered a few. They were around $20-25 each. I also bought a portable monitor for similar tasks, which has been really helpful. A USB media keyboard with a built-in touchpad is another useful addition—it’s much more convenient than handling monitors or PCs.

I purchased inexpensive fans; they turn up the noise much more than the previous models.

It didn’t work as expected. I entered the BIOS, adjusted the fan settings to quiet, but the sound remained unchanged. The motherboard appears to be quite old, possibly predating current 4-pin PWM controls.

Discovered some gold at that link – probably related to Gigabyte UD5H fans. It seems I might have too many fans now, having kept a few old ones, so the issue likely involves connecting one to header 4.

Success came from just turning off the fan connected to SYS_FAN4, which quieted the issue completely.
