New Dell server - internal fans going crazy

[TwistedHelixis]

I have just unpacked and turned on a new PowerEdge T560 server.The fans all sound like they are taking off and are not throttling down, like they do on my older server.I have installed all available firmware updates using the Lifecycle controller.I have opened idrac to check for any system issues. Initially it listed intruder sensor alert, but after clearing the log, that is no longer displayed.I can also see in idrac that all the fans are running at a constant 50% PWM. They are not going up or down from this.

 

I have not tried to install the OS yet, as I want to get the issue fixed first.

 

I have just sent Dell a message, but got a reply they are not available until Monday. Problem is, I was booked in to get this up and running with host and VMs OS's installed on Monday / Tuesday, as the school is not open for staff or students on those days next week :-(

 

Anyone come across this issue before?

Probably over simplistic

but have you looked at the BIOS - or whatever - to see if it is set to constant speed in some setting ot other

 

or checked the cpu temperate to see if it is OK

 

and, of course, check there is no packing doofer that is blocking the air flow

 

anyway - good luck with it

I was just about to give up when I read that newer Dell servers don't turn down the fans while in the BIOS, idrac or lifecycle systems. They only use the temp settings while running an OS.

 

Just installed Server OS and the fans have turned way down.

I had this with a T550 recently.

 

Ours was caused by the backplane not being recognised by iDRAC correctly.

 

I opened a support case with Dell who suggested a power drain (I also disconnected and reconnected the back plain) which resolved the issue

Good to hear this. Is the moral in the story not to agree to work over the weekend?!
