I tried to go down this route as well with my setup. I also get a /60 prefix from my ISP (AT&T) and currently have my edgerouter 4 delegating prefixes to all my VLANS. I posted about his previously in this thread but never got any real direction on how to get the ICX to handle prefix delegation. If you want to read through that conversation you can start at post #3323.

HW: Stackable ICX6610-24-HPOEMB40201VX arrived today. Swapped it out and it's about the same noise level and feels about the same airflow as the stock fan. Overall it is a tad bit quieter since there was some sort of a bad bearing noise on the stock fan. However, the switch still isn't lowering the fan speed on boot. Just to make sure I put the original fan back in, booted it, and it also doesn't drop the fan speed on boot. The only way I can get the fan to slow down is with the dd set_pwrfan_low command. Is this correct, or is there something wrong with this switch?
Fan ok, speed (auto): [[1]]<->2
Fan speed switching temperature thresholds:
1 -> 2 @ 69 deg-C
1 <- 2 @ 64 deg-C
Sensor B Temperature Readings:
Current temperature : 50.0 deg-C
Sensor A Temperature Readings:
Current temperature : 62.5 deg-C
Warning level.......: 66.0 deg-C
Shutdown level......: 76.0 deg-CFan ok, speed (auto): [[1]]<->2
Fan speed switching temperature thresholds:

Warning level.......: 66.0 deg-C
Shutdown level......: 76.0 deg-CNo, definitely it should lower the fans. But I'm placing my bet on a software issue, because the fact that it can slow down the fans when forced with the "set_pwrfan_low" clears any suspect of a bad PWM circuitry and what not. Maybe once issued one of the two set_pwrfan commands it won't fall back to an auto speed regulation... I have to call @fohdeesha, I don't have an answer for this, sorry.
. You have at least 13°C of headroom until the forced shutdown.Honestly, a 1U box cannot be as quiet as a desktop PC using 120 or 140mm fans... The wider the fans the lower the noise they make moving the same amount of air.
This would be pretty much every HP server... I have 2 DL360pG8's and 2 DL380pG8's on top of 2 icx switches.. and it sounds like a jumbo jet on takeoff when the rack comes up after a power failure (my UPS can only run them for about 15 min)
Hello, @ViciousXUSMC -- I remember you well from the Aruba S-series thread; another thread that made me spend money! Ha Ha!
Yes the S2500 served me well, but the 6450 was more efficient, had more power budget, and was actually quieter after the fan mods. I wanted to explore the CLI more and try to get more videos up so I was doing it just to do it more than out of any real need.
Curious, if they are all in one setups, even 3, why are you using so many ports. I have 2 DL360ps with 2 port 10GB intel, and 4x1GB flexlom, and 2 DL380ps with the same. I'm only using 3 ports per machine (2 10GB ports and 1 1GB for backup connection to the switch), plus 2 ports for my ubiquiti setup ( each setup consists of 1 AP and 1 POE powered 8 port switch, AP gets power from the 8 port, the 8 port from the brocade, so only 2 ports there).
I'm also having the same problem as noise850 with the switch stuck in high speed fan mode, using the command he used I can lower the fans. I tried a reload with the fans set to low, and at the same time as the "enter b to stop at boot" the fans changed to high and stays like this. I have a 6450-48 non p model just updated using the file from the guide (08030t). There is also some kind of whining noise running in low. It may be present at high too just non audible when the fans are a bit louder.No, definitely it should lower the fans. But I'm placing my bet on a software issue, because the fact that it can slow down the fans when forced with the "set_pwrfan_low" clears any suspect of a bad PWM circuitry and what not. Maybe once issued one of the two set_pwrfan commands it won't fall back to an auto speed regulation... I have to call @fohdeesha, I don't have an answer for this, sorry.
IMHO, if those are your maximum temps in the hottest days, I don't think that it hurts keeping it on the lower speed, at least until there's an answer to the previous question.. at least, it's easier on your ears
My earlier quote about how there's "No kill like overkill" applies here. I only use so many ports because of that mindset. Hey, I've got 'em -- why not use 'em?
Mine has it as well, I think it's due to the low-ish frequency of the PWM modulation used to lower the fan speed. Maaayyyybe it's possible to make it go down by adding some capacitor to smooth it, but I don't want to advise anyone to add some random caps... I don't want to risk someone's equipment.
Thank you! adding a 330µF cap removed the whining noise.
