So after getting the switch back up and running (very much in testing mode here).. The fan was not sufficient to keep the ASIC temps in low-range territory. I'm going to either 3d print a duct to work with a few extra 12V low noise fans from the side vent, or I'm going to have to put something directly on the ASIC.I am curious. What about AISIC temperatures in your ICX 7250-24?
I did the same on my ICX 7250-24P. This device even has two fans. But the two Delta EFB0412VHD-F00 were not sufficient to keep the ASIC temperature down and frequently step 2 of the fan control jumped in. I had to add an additional fan on top of the cooling fins for the ASIC.
