*** WARNING *** I am a complete newbie at this!

So I just received a new Nutanix rack mounted server from a friend, two nodes and I don't intend to run Nutanix on it.

I don't have a rack or means of mounting it so it is just sitting on a table for now, without any soundproofing. Is it possible to use pwm to control the fans? As far as i can tell, the motherboard can control the fan speeds, like at startup.

Could i replace the fans with a noctua fan?

It's easily possible to fuck with the fans if you know what you're doing. Most of the time they're loud because the chassis fans are trying to push air through heatsink fins a couple of feet away from them. Sticking active coolers on the sockets is a good way to calm them down a bit.

The guy who gave it to me mentioned the loudest thing is the power supply, but the main fans are easily the loudest. Do you think there is a way to mod the fans slower or maybe put it in a consumer case?

Check bios for lower fan profile.

Can also add a pci slot fan or whatever additional fan you can fit. Idea is extra fan keeps idle temp lower so loud fans don’t spin up as often
