After the problems I wrote down in this topic I re-deployed the latest SPP (including the latest ASM, which wasn't installed before) and I upgraded iLO to 2.42. Now the fan won't shut up. :huh: I did some tests, even at a 20*C inlet temp. the fan wouldn't go under 19-20%. I am running AHCI, but during the winter the fan was sitting around 9%, just like Shonk. Now the temps are slightly higher due to the summer heat, but it's still odd that they went so much higher after the update.

 

Any advice?

Thanks.

To show they are in ahci mode

Hi Shonk,

 

Slightly off topic, but are your WD80EZZX plugged into the Microserver bays? and the B120i in AHCI mode?

 

I only ask because my WD80EFZX are not detected on the B120i in AHCI mode :(

Yes The 4 x WD80EZZX's are all in the gen 8 bays

I can confirm the lower fan speeds on mine as well in AHCI mode.  Currently at 16C inlet temp / 7% fan speed.  Running XPEnology bare metal, with a custom build of HP-AMS I did for XPEnology so things show up in iLO.  It doesn't however correctly report HDD details, and I haven't noticed that the fan speeds are any different from when I didn't have HP-AMS running.

 

4x 4TB WD Reds in the bays, plus an SSD in the ODD space.

Please report fan speed when you have -say- 22C inlet. (could that be around 14%?)

22 inlet is 12% if everything else is low enough

Hmm, well the WD EFZX Reds don't work in AHCI mode so you got even luckier with the EZZX not just price! they get turned on/off twice during the initialising ahci and are not detected (the 1TB 2.5 in bay 5 is detected). In RAID mode they are turned on once and are detected fine, although I'm having to not configure them as RAID 0 as the 1TB HGST throws a over-temperature alarm.

 

The joys of Gen8 bios!

 

More OT: In RAID mode without drives/AMS etc with freenas I get 13% fan, but that's 22/23 inlet temperature. AHCI was the same when I was testing with another drive.

 

I did notice the lowest fan speed of 6% one time when I forgot to plug in the internal temp sensor cable after taking the board out for a xeon swap.

Yeah, too cold in the house to get inlet up to 22C, but looks like that's what it would be on my setup:

16C - 7%

17C - 7%

18C - 8%

19C - 9%

20C - 10%

21C - 11%
