Re: DL380 G8 fans.
The DL380e Gen you have is the "Storage" model that has parts that are not included in the standard (non-Storage) DL380e Gen8 model.
As I mentioned earlier, you need the entire Drive cage and Hood (not only the drive backplane). HP cannot send you parts from one submodel to make up another submodel because, those part numbers are not even listed as replacement items for the unit you have.
Try to return that unit as a whole and then, get the DL380e Gen8 base model plus the P420 card.
BTW, I was finally able to get ahold of a Primary Riser with SAS and I see no major difference with the temperature of the P420 card. I was only able to lower the FANs to 33%. Any lower FAN speed causes the P420 temperature to increase towards 90┬║C.

Re: DL380 G8 fans.
It's been a few weeks since I contacted HP and it's taken them all that time to tell me that there's nothing they will do for me.
From their point of view, it's my problem as I should have known this before I bought the unit. Everything is working 'as intended'. From my point of view, it's such a specific issue linked to 2 pieces of hardware that there was no reasonable way for me to know about the issue before purchasing. Furthermore, when contacted for help, HP didn't know about the issue either.
Also, according to HP's Level 2 support, the system isn't smart enough to know if the drive cage is fully populated or not. It runs the fans at a minimum of 35% for the possibility that the drive cage is fully populated. Even if the P420 controller is cool (50C or lower), it won't drop the speed of the fans.
Bottom line is that I will have to pay for a new SAS controller or new drive cage if I am to reduce the noise. I'm truly disappointed with HP and I don't think I'm being unreasonable in requesting help from them. I'm confident in saying that I won't recommend HP servers to my clients anymore. The support is quite poor.

Re: DL380 G8 fans.
I just wanted to ask if it would be possible to lower the fan speed of the 3 system fans in an ML350 G6?
I currently have it as a home server which is awesome due to the power, scalability and reliability it offers. However it's bloody loud to have in an office!
I have tried changing the fans for other PWM fans and moddifying the fan connectors so that they register correctly, but despite iLO saying they are running at 25%, they appear to be running at full speed which is highly frustrating!
All temps within the server are good and all but 1 sensor report temperatures south of 45C, the ambient room temperature is 19/20C, so it should be sufficient.
Oscar, you mentioned that you used the iLO debug to manually change the fan speeds, how did you do this?
I hope that someone might have the miracle answer I'm looking for!
Thank you all in advanced!
Kind Regards
Josh

Re: DL380 G8 fans.
Josh,
I have a ML350 G6 with two processors and 4 fans and they are running at 13%. How many processors do you have? Did both come installed or you installed the second proc later?
I'm asking because, this unit has 4 different configurations, some of them for 1 Proc come with a small Baffle, some of them require a large Baffle. Open the hood and look at the label.
Also, check in the BIOS under Advanced Options->Thermal Configuration. Mine is set to "Optimal Cooling".

Re: DL380 G8 fans.
Thanks for the response, mine also has 2 processors installed (E5520) which were installed at the same time along with 3 fans. I have also tried adding a forth fan at which point they all then run at 21% instead of 3 at 25%, but it still seems overkill and noisy.
It has the latest BIOS, iLO and power controller firmware and the Thermal Configuration setting is also set to Optimal Cooling.
The system is running ESXi 5.0.0 Update 3 and is the custom image from HP for this server, but I have also tried Server 2012 R2 to see if running that with the latest drivers and software cures the fan speeds, but unfortunately it does not.
Any ideas?
Kind Regards
Josh

Re: DL380 G8 fans.
I have two servers 380e 668668 25 SFF with latest firmware and software.
These new servers is taken from warehouse after a half-year conserveation.
I see a 13-20┬░C from sensors during loading process. And then after temperature calibration severs set ON a supersonic fighter mode.
I created a tiket in HP support and send them AHS logs to analizing.

Re: DL380 G8 fans.
HP suport answered me with recomendation to move a cooler from 6 slot to first.
Server became quieter!!
Now i have 5 fans in 1,2,3,4,5 slots and 6 is empty.

Re: DL380 G8 fans.
I believe when I tested mine, I had all 6 FANs populated.
Since the P420 card inside that storage model requires a lot of air to remain cool, I would advice you to add an extra fan for slot 6.

Re: DL380 G8 fans.
I just checked some of my servers in one of our colos... they're all in the same cabinet with the usual hot/cold aisle setup:
DL360 G6: ambient =33C / fan speed = 61%
DL380p G8 (16 SFF): ambient = 32C / fan speed = 6% for 1-3, fan 4=36%, fan 5-6=45%
DL380 G5: ambient = 27C / fan speed = 48-54%
DL360 G7: ambient = 23C / fan speed = 38%
Not sure why that G7 reports a lower ambient temp. Weird. But at any rate, the fans do generally run fast across the different generations.
In fact it was only the G8 that had some of the fans running slower thanks to it's "sea of sensor" technology which really does try to get more airflow just to the places that would benefit.
And as noted earlier in this thread, thanks to the handy 3D view of the temps, it does get hotter over in that PCI card area. And my particular system has the 8-drive expansion so I've got the 420i plus an additional 420 controller installed, so it does get plenty hot back there in that corner. 85C for sensor 29-PCI-2.
But I only have these servers within hearing range for a short time while I configure ILO, and then it's off to the server room, well away from my head. And let's face it, when you're in a crowded colo with acres of servers, the noise of your puny system is lost like a drop in the ocean. :)
If your needs require quiet servers, I'd suggest something a little more home-grown like a desktop with liquid cooling, but if you wanted to be creative, take any of those gaming rigs and look at the heat pump designs with liquid coolers, and you could probably rig something up to get air into that back corner of the DL380 G8 where it's needed most.
You could even try something as simple as installing one of those PCI cards that's nothing more than some fans to blow air onto whatever. Usually used as additional GPU cooling in gaming rigs, but if gets a little more air going past a hot P420, that's not too different.

Re: DL380 G8 fans.
May I ask what OS you are running on these servers with the temp control issues?
