T630 fan speed high after RAID controller replacement

Hello,

please can you perform a iDRAC reset?

Here the procedures:

Hi Marco,

I've already reset all settings as described under "Reset using the iDRAC Settings Utility" and power cycled the server multiple times. 

Thanks

That's very strange.

In the H730p controller BIOS you should see the ROC and IOC temperature, can you check which is the value?

Also, you can export PERC TTY logs with PERCCLI using this procedure

Maybe there are some information about some errors in the PERC.

Check also the environment the server is in, and try to reseat PERC again.

Also if other components in the server are overheating.

Thanks

Marco

The issue exists with no controller plugged in. As soon as a drive is inserted into the backplane, fans ramp up. 

Disk temps are all ~26c.

CPUs are at ~35c. System board inlet temp is currently ~16c. 

PERC has been reseated multiple times now. 

I suggest you to perform a IDRAC reset from web interface (idrac reset, not reset to default setting).

I think that the reset you performed just reset default settings, but it doesn't reset the idrac.

If it doesn't work i think there is an hardware issue on the motherboard.

Thanks

Marco

iDRAC reset from web interface has sadly made no difference.

Is there any way of checking what could be triggering a hardware issue as you describe?

Hello joneilosco,

When fans are running high; Can you confirm if all fans are running? If one fan is failed the others may ramp up to compensate.

Do you have the cover installed? Fans will also run high if the side is removed. Try reseating the fans.

Have you checked the system event log and lifecycle log, in the DRAC, for any error messages related to the issue?

Next I would recommend running the built in diagnostics

Boot to  F11 on Dell Splash screen, selecting  Boot Manager -> System Utilities -> Launch Dell Diagnostics.  Note any messages and continue testing.

Hi Charles,

Both fans are running (and at the same speed). 

The cover is installed.

Fans have been reseated several times since this issue began.

System event logs and lifecycle log are both error free.

Pre-boot diagnostics has come back with no errors. Oddly, I had to disconnect the optical drive. With it installed, diagnostics was reporting a CD drive that doesn't exist and would hang waiting for it to become ready. With no drive connected fans still run at the same speed, even after draining flee power and resetting iDRAC. 

Joneilosco,

I would suggest taking the server to its minimum to post configuration, which is removing everything internally and externally but the following;

•One processor (CPU) in socket processor 1 
•One memory module (DIMM) in socket A1 
•One power supply unit 
•System board 
•Control panel 

Once everything is removed then power up and see if the fans ramp up. If they don't then power back down and then individually add the removed devices back, each time powering up to see if the fans ramp up, this will help identify the part causing the issue. 

Let us know what you see.

Hi Chris,

Fans will slow down within seconds of removing all hard drives. These are the same drives that have been in use for over a year with no issues until now. 

Hi Erman,

The problem does persist when using the original controller. 

I don't have any alternative SAS cables to troubleshoot with unfortunately, however storage devices appear to be perfectly functional.

I'm using the "Performance per Watt (OS)" system profile, so C1E is enabled. 

Hello,
As far as I can see in previous posts, you have already done many troubleshooting steps and firmware updates. It's interesting that the fan speeds slow down when you remove the latest drives. Does the problem persist when you plug in the old controller? In case there is a problem with the parts of the SAS-chain, if you have the opportunity to try, can you change the SAS cables and try?

Apart from these, I would recommend you to try these two settings by changing the BIOS, disabling "Turbo Boost" option in BIOS setup. Or, if C1E is disabled, the fans can run at high speed to cool the CPU, Can you check C1E is enabled. These setups may be a workaround till new FWs released because if there is no hardware issue I'm suspect current FWs. 
In the F2 BIOS,  SystemBIOS > System Profile Settings >

No warnings in iDRAC.

Fan speed is around 2.9k or 55% PWM. 

Fan Speed Offset is off. 

Hi, Could you check system event logs on iDRAC? Is there any warning? What is the current Fan speed RPMs? and Could you check Fan speed is still Off, System Setup > iDRAC Settings > Thermal > Fan Speed Offset > Off
