DL20 Gen10 - M.2 NVME high FAN speed

[marcellinus]

Hi

I have installed a NVME in the DL20 Gen10 Server for the Operating system. However, when the NVME is installed, Speed of Fan 1 & 2 is never below 71% (which is quite noisy) despite the temperature of the drive. Is there a setting to mangage this a bit mor "noise freindly" ?

To confirm, if I remove the NVME and boot the OS from a drive bay, all is fin, fans regulate depending on load and temperature.

Kind regards

Is it a 3rd party SSD? That'll do it.

Hi

It is a Genuine HPE component, I use drive 875490-B21.

Is it maybe required to have the dedicated ILO port installed? I use the M.2 directly attached to the Mainboard, not having this ilo board in between.

Yes, the dedicated iLO port is required, that's what gives you a usable m.2 slot. What's on the motherboard isn't made to plug an SSD into.

Thank you. 

This is strange, the service manual states that a M.2 can be installed in this slot directly, and also has specific mounting positions. If this is true, the manual is WRONG there.

However, I am going to try again with the dedicated ILO port installed.

I checked the SmartStorage Administrator, the drive shows Temperature 33 deg. C. so technically all works fine and there is no reason for the high fan speed, thoug!

I do see what you're seeing in the service manual, which doesn't match the rules in quickspecs, but I think I've identified the main issue. That slot is for an NVME M.2 drive, and you're using a SATA M.2 SSD. The only supported SSD in that slot or the iLO kit is 875583-B21 which is NVME. In order to use your SATA M.2, you'll need to add HPE Universal SATA HH M.2 Kit (878783-B21) which occupies a PCIe slot.

Hi Marcellinus,

Did you end up succeeding in reducing your fan speed? Curious to know what your findings were.
