THAT IS QUITTER TALK. Anything can be cooled quietly, just a matter of engineering and design trade offs. This isn't rocket science. I'm sure slapping two 180mm fans on top would do it easily with lower than stock temps, but it is more work, and would make it take up more rack space. Someone else did this with a ICX 6610 which has a higher TDP.
doh!

Yup, I was one of the first ones to mod a 6610 with 3x 120mm fans on top.
Instead of being dismissive, how about actually being helpful and share a data point like was asked.Yup, I was one of the first ones to mod a 6610 with 3x 120mm fans on top.
Like I said no good way...
I exchanged on my 7250-24P the two fans to Delta EFB0412VHD-F00. This was a huge improvement for noise but now I got a temperature issue. I am waiting for the Sunon MF60101V3-1000U-A99 fan I ordered to put on top of the ASIC. Unfortunately, I could not find any other alternative with thin height and have to be patient due to long delivery time.
Did you order from Mouser? They have them in stock right now (that's where I bought mine from).
I'm ordering the MF60101V1-1000U-G99. It's rated at 28ish dbA which better matches the dba rating of the 40mm fans. No point in sacrificing airflow when any dbA benefit will be canceled by the louder 40mm fans. Also thanks for pointing me to that post by roachedcoach, I overlooked that one in my search.
Not being dismissive, just pointing out the obvious. These are 1U devices packed with enough hardware to do serious switching. 1U devices are inherently difficult to cool, silently. If there was a good, easy way to keep them cool AND silent, the interwebs would have their panties in a bunch by now. But they don't.
I'm not going to debate the thermal engineering with you, and I never asked for or wanted your opinion on the feasibility. I was simply asking for specific data to use to make my own decisions with. You do you.
The C12P's SFP and 'uplink' ports (C1,C2) can certainly be used to wire LAN devices. The RJ45 uplink ports don't provide PoE like ports 1-12 do.
I'm sure the switch would support the GPON transceiver (the 10G ports run in 1G mode when not licensed); whether or not your ISP supports it is another matter (or if you can work around it).
Those fans can draw a handful of watts each at most, many won't even reach a single W of power consumption... I don't think that your issues with the breaker is anywhere near related to the fans, but I suspect a general overload of the circuit, that after a couple of minutes with the additional consumption of the switch itself (not the fans!) trips the protection.
I have had this switch on for hours in my office prior to the fan swap, that's what puzzles me...
Maybe you're "at the edge" of the allowable power draw of the circuit and a small "kick" of ~100W or so during bootup may be enough to trip it... you'd feel the breaker being warm in this case, and it might not even want to stay closed right after it disengages in the worst case.
The Delta I bought from Mouser. The Sunon I ordered from RS.
My plan is first to connect this fan in parallel to the housing fans. So, it will run at fan level 1 anyhow slower and at a different noise level. If this is not enough, I will connect it to permanently 12 V. This is my plan. No idea if it will work. I can report later.
