I am starting a new thread on the ICX 7540 because it is somewhat similar to the ICX 6610 but after opening it up, it is definitely not the same. I have the 24P version with modules for 2x 40G QSFP+ ports and 4x10G ports.
The switch ASIC and the CPU are covered by a single larger heatsink. There is no separate POE board on the 7450, it's all a single PCB that has everything on it so the In addition, the beefier the POE injectors have much beefier heatsinks than those on the ICX 6610's power chips. The ventilation in this chassis from the delta fans isn't doing much so my guess would be that a single 140mm or 200mm fan should do the trick on this chassis. particularly if you're not planning on loading up the 8x90W POE (which I am assuming no one will in a home lab context.
Note: The power supply and fans are exactly the same as the ICX6610 and just as noisy. The power supply in my 7450 is a rev C, while the ones in my 6610 are Rev A and they are identical noise-wise as far as I can tell. The fan module is also identical to the ICX6610 using the same Delta 23k RPM fans.
Here's the starting point. My (not so accurate) iPhone SPL Meter shows the noise level as 56 dBA at the faceplate and temperature after an hour-ish and no load are as follows.
After replacing the fan module with a 140mm Noctua over the CPU + Switching ASIC:
