I have a supermicro chassis (RM41300) and a supermicro board (X9DRD-iF) and all of the components are new. When I power it up, it all powers on fine and the OS boots and everything is hunky dory.
then, about every three mins or so, a steady alarm sounds and it revs up like it's booting, as in all the fans kick in and it sounds like a jet taking off. Then it dies down again. Three mins later, it all spins up again, then it dies down.
I was thinking heat but it starts this almost right away, it's all new and it's under no load.
There is a fan in the front that's not spinning so it could be bad, but I'm not sure what's causing it. Of course, it seems like a hardware issue.
