Zero fan curve

[Cramig88]

Long story short…

bought a server off Craigslist.  Whatever, 700$, 2x Xeons, 384g of ram. Something. Quite a score right?

well the thing is loud.  I get it, passive heatsinks. Duh, it’s a server

Let’s watercool the CPUs!  Done.  Now it’s confused. Pump is DC/molex - straight full power, yet at 37c all 10 fans go super fast then idle and back again

There aren’t any fan curve options in the BIOS let alone a Cpu header, I just see fan0-6. Tore apart the manual too, watchdog and stuffs

 

TLDR;

got a server, fans are always super loud. So STFU, watercool it. Now it’s 100% to 20% and back to 100. Annoying.

help? (Yellow duck as a life raft)
