Netgate RCC-VE 8860 FAN noise
-
While it is technically possible to control the speed of the fan we can't release anything to do so until we know what speeds are considered safe, acceptable heat levels, etc. Quite a lot of actual engineering work involved there beyond the technical issue of changing the fan speed. There would be even more trouble if we released a utility to adjust the fan speed and someone ended up burning up a unit because of it.
So it's less about if someone can adjust the speed and more about if they should or if they can do so safely. The latter two are much more complicated questions that, given the level of noise in its typical operating environment, would take a large amount of work compared to the benefit of said work.
Swapping fans, using low-noise adapter cables to cut fan speed, lowering the CPU fan speed on your own through other means, etc, would probably result in a quieter unit but until the legwork is done to verify the cooling is sufficient, it is too risky for us to officially condone.

My problem with this unit for me as a customer is very simple. I've bought that product based on the information I've found on the vendors page. And netgate is still telling that it's a low-noice fan. And I think all know that is not the case.
So I'm asking to make it operate at low-noice. How they can arrive that goal doesn't interest me much. They are telling it's low-noice so I'm asking them to make it low noice. -
I think the fan is always running at full speed. Temperature stays stable at 22.0Ā°C.
But this is quite better then the CPU is smoking up and all is quite.
At least I know it's not only my unit. For now it's louder than my Xeon Serverā¦
I own a Intel Xeon E3-1286v3 @3,7GHz and this is water cooled but before as I really cool it down
with an air cooler it was also really silent, but not in such a case like the SG-8860 desktop appliance.Selling it as a "desktop system" is rather misleading.
Check your product description.The C2758 platform is sold as a 1U and as the SG-8860 variant, so called desktop case,
and where now is the problem? All other vendors do also offering their equipment as I
see it right.Quite a lot of actual engineering work involved there beyond the technical issue of changing the fan speed.
I had be more loved a cool device thatĀ“s long time running more then a quite device that is earlier
dying but quite. -
@cmb:
The guy who claimed to have a Xeon that's quieter apparently has the quietest Xeon on Earth. It'd take a dozen 8860s to make as much noise as one of our Dell 1U servers. I can't even hear the fan turn on when firing up an 8860 in our computer room. It is noisier than I would want running on my desk next to me long term, though that's true of every similar class product with a fan in it.
Well, even servers nowadays have variable fan speed. My Xeon server also slows it fans down, and with the right bios settings (and fans) it is rather quiet. But 'noise' also has to do with the fan diameter, often those 12 cm fans are also making noise, but with a noise 'profile' that's easier on the ear.
But, if you already have one of those 8860 units, why not modify it? Remove the built-in fan and put a large silent 12 cm fan on the top. Of course you need a bit of knowledge, and if the built-in fan has PWM, then by all means use a PWM fan. Or try your hands at a really large heatsink.Ā :)

I already own a 8860 unit. Why should I change components in it? I've bought that products because they have told me it's a low noice fan. So I don't like to replace anything in it (warranty).
They should simple use the EMC2104 chip that is on the board. This chip is also able to shutdown the unit, if it gets to hot:The EMC2104 is an SMBus compliant fan controller with up to five (4 external and 1 internal) temperature channels. The fan drivers can be operated using two methods each with two modes. The methods include an RPM based Fan Speed Control Algorithm and a direct fan drive setting. The modes include manually programming the desired settings or using the internal programmable temperature look-up table to select the desired setting based on measured temperature.
The temperature monitors offer 1Ā°C accuracy (for external diodes) with sophisticated features to reduce errors introduced by series resistance and beta variation of substrate thermal diode transistors commonly found in processors.
The EMC2104 also includes a hardware programmable temperature limits and dedicated system shutdown output for thermal protection of critical circuitry.

I am considering to this really!
But on the other side why imagine that the strongest and biggest pfSense appliance is quite!
Either it comes as desktop model or 1U applaince!!! Ok if you place it on your desktop and
then nothing else is running it could be that you might think the SG-8860 is very loud.They should simple use the EMC2104 chip that is on the board.
And you mean this could be done because it is only technically doable?
This chip is also able to shutdown the unit, if it gets to hot:
And if only you and perhaps two other peoples are complaining now, but not
all other 600 clients this must be done? Hmm, ok if you mean this must be
done perhaps they will find a way for you! -

In the same room I've running a Synology DS1511+ and a Lenovo P500 Workstation, and both of them doesn't make as much noice as the SG-8860 when the are idle (compared all devices when they are idle).

I just picked my Sound Level Meter and had a look at the noise level.
My Xeon, distance 30cm (in front of the fan): 39.5 dB
The SG-8860, distance 30cm (in front of the fan): 45.2dBIn my opinion that's too much to call it a "silent fan".

It's no longer labeled as such, and hasn't been since the initial complaint. Heck of a quiet Xeon. jporter was using a sound level meter on an 8860, and my keyboard on the other side of the room measured much higher than the 8860. Granted, I have one of these keyboards, and type about 100 wpm. :)
-
You're right, it's not labed as silent. But it's still labeld as "low-noice" at least in the netgate store.
And it's still far away from "low-noice".
Compare with a keyboard is a bad comparison. Compare it with other computers. Comparing it with a keyboard is like comparing apples and pears. -
So last info from the vendor is, it is as it is. They will not do anything.
For me this means, don't recommend hardware from them to anybody. Because do will not always delivery you what the have promised you.
