Hello,

The fan speed you listed is within operational allowances, so there may not be any options. However, you might try restarting the iDRAC with racadm racreset -h. The iDRAC functions as a fan controller so restarting it may help. If that fails, you can try performing a power drain by shutting the server off, unplugging it, and holding the power button down for about 30 seconds. If the fan keeps running at a high RPM, the firmware may be doing it deliberately. I did find a link when searching the forum that might help you with some IPMI commands. You can compare what you have with what they used. I can't recommend this though, as it may lead to insufficient cooling and problems arising from that. I don't think you can set maximum cooling speeds, but you may check in the location listed in the owner's manual for thermal control options: https://www.dell.com/support/manuals/us/en/04/poweredge-r730xd/r730xd_ompublication/changing-the-thermal-settings?guid=guid-6aa43bf5-38bb-49c3-9f28-adba64d3ac88&lang=en-us

I just wanted to say that after updating bios and idrac firmware on our R730xd, I too had full speed fans.

The solution provided above worked for me, which was power down the system.  Unplug power cords.  Hold power button for 30 seconds.

After re-plugging power cords and starting up, no problem.

Hi, 

I have two PowerEdge R730xd and I have a problem with the first one for the ventilation (always run at 87%). The two servers have the same version of firmware and the same revision of the system. 

- I restarted the iDRAC with racadm racreset -h and I tried the unplug power with the hold power button. 
- I changed the thermal profile in the iDRAC but I still have the problem. 

Any idea that I can try to solve the issue?

Thanks

Hi, to see why your fan is running so fast we would have to compare your system to another one for number of cards plugged to the riser slots (or the type of cards) and how BIOS settings are different, too.

Understanding why the two system's are cooling differently really isn't something we can get into, because it is firmware controlled and influenced by numerous internal and external factors. The best recommendation we can make is to make sure your firmware and OS are up to date. Considering the concern is cooling, I would review all firmware in the system, not just the BIOS.

Hi, 

I compared the two servers and here are the differences: 

- CPU Xeon ES-2640 for the server in problem instead of ES-2650. 

- RAM running at 2133Mhz but could be at 2400Mhz (Micron MTA18ASF2G72PDZ-2G3B1). The other server run at 2400Mhz but it's not the same model (Hynix). 

- ESXi is installed on USB drive instead of SD Card. 

- I can start the Console only with Internet Explorer instead of Chrome. 

- In LifeCycle: Disk version is PT51 instead of EB01 but it's not the same HDD. 

All of the settings or version or hardware are the same. 

- In LifeCycle, the fans run at 45% instead of 25%. 

- In LifeCycle / System / IDSDMRollupStatus = I have nothing instead of OK. 

When ESXi start the loading of the software, the fans goes to 87%... It's ESXi 6.7.0 build 15820472 Dell profile image. 

Thanks for your help. 

Hi, 

I try again the firmware update with the last Server Update Utility (SUU-WIN64_20.12.200.458) and all the firmware are up to date. 

Anything else that I can verify? 

Thanks

Not without removing the non validated SSDs. It is possible that is what is causing the higher fan speeds and there is not a validated method for changing it. 

take a look there

In short:

Set Third-Party PCIe Card Default Cooling Response Logic To Disabled:

ipmitool raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00 

You need to make sure IPMI is enabled in iDrac. Install openIpmi in your system OS. 

I did the IPMI trick but the fans only drop to a normal speed for about 2 seconds, then ramp back up again to 46%.
The 730xd does not work correctly with non-Dell drives.
I think that is absolutely terrible of Dell to pull this kind of stunt.
