You can splice into one of the existing fans. I'd recommend using new connectors instead of trying to splice the wires themselves.

Add a fan to the ASIC heat sink. I used a Sunon MF60101V3-1000U-A99 in my 7250-48P. I also suspect the fans you swapped in aren't really up to the task (10.3 feels kinda low to me, I think something in the 17-19 range would be better), but you'd have to see if the ASIC solution at least got you...

I run mine in the back - just makes a heck of a lot more sense from a cable management perspective. Didn't reverse the fans - didn't seem to matter.

Yes, attach it to the CPU heat sink. Sorry, I wish i'd taken pics of this at the time. There's no perfect attachment points, I just used some heavily threaded screws and they bit into the heat sink enough that it holds it in solidly. I never found myself having to cool the SFP area, seemed...

Here's what I did https://forums.servethehome.com/index.php?threads/brocade-icx-series-cheap-powerful-10gbe-40gbe-switching.21107/page-159#post-256375

Anyone here have much experience with the Guest network? I set one up for the when the family visited over Thanksgiving and every user (regardless of device type/OS) had to login twice. First time would always fail, second time would work. Is this a known thing, or anyone have any thoughts on...

I replaced mine with Mechatronix, they've been perfect for me. Best bet is sticking a fan on the ASIC as well, makes all the difference.

Wanted to plug my post on my fan changes to a 7250-48p. https://forums.servethehome.com/index.php?threads/brocade-icx-series-cheap-powerful-10gbe-40gbe-switching.21107/page-159#post-256375

Make sure the fan is attached to the ASIC heat sink, not the case. I used screws and just screwed right into the fins of the heat sink. Been great for almost 2 years now.

That is running really hot...you're ok with that?

To go with the supercomputer they're selling. Mentor Graphics Veloce2 Quattro "System on Chip" SoC RTL Emulator Supercomputer | eBay That's a lot of switches, lol.

My 7250-48P pulls around 55W with a few PoE cams attached. I'm still convinced the 7250 is THE best L3-10G switch for homelab use - considering low power draw, fairly low noise (moddable even moreso) and switching power, plus it's a fairly recent/supported design.

This is what I did. The secret sauce is slapping a fan on the ASIC and changing out the fans. https://forums.servethehome.com/index.php?threads/brocade-icx-series-cheap-powerful-10gbe-40gbe-switching.21107/page-159#post-256375

You absolute monster. Bravo!

It sounds janky, but honestly, just drive the screws right into the heat sink. Well-sized and threaded will grip right to the fins very securely. That's how I did it.

I'm biased since I wrote a lot of the posts, but for the 7250, I'm all in on the Mechatronics for the rear fans, and the single Sunon for the ASIC fan. Pay close attention to the model numbers in the posts. And if it's cranking up every so often, probably a room temp/airflow issue, so do...

Just to jump in on this - I want to be sure you purchased the Sunon (or similar) fan for the ASIC as well - that's sort of the magic that makes this all work. You also need to have it when you crimp the rest of the fans since you need to wire it in to fan 3 (assuming you're doing all 3 fan headers).

What? Tubs had a 7250-24P https://forums.servethehome.com/index.php?threads/brocade-icx-series-cheap-powerful-10gbe-40gbe-switching.21107/page-256#post-297209 OP also has a 7250-24P...

Agreed, we have no way of knowing for sure. I remember reading your post about the PSU popping and letting out an audible groan. For anyone going forward, my best rule of thumb is to match the replacement components as closely to the originals in terms of performance. I'm going off the...
