For some reason I thought this was a solution to make the switch quiet and keep the SFP's really cool, because when I tested the RJ45 SFP the other day they worked fine, even at multi gig speeds and my desktop has been hooked to one for weeks no issues, but soon as I added my access point using one it got super super hot and the AP messed up and I cant say if it was a fluke with the AP or not but I think the SFP got hot enough to cause issues.
My brain took this heat problem and just assumed that was the problem you were addressing, as everything else is running cool enough without an extra fan.
Adding an external fan is a solution, and I have a great fan for it already (the ones I use ontop of my AVR in the theater room) but I wanted something clean and intergrated so that way my rack is self contained and my dog or whatever cant mess it up.
Looks like I may just have to go with plan B, I got this switch and can just use it in conjunction with my ICX 6450 and just have the 7250 for (another) backup.
