I've managed to pick up cheaply a Dell Powerconnect 5224 24 Port Gigabit switch.
I wanted to use it in my home network and using it with the std 3 40mm screamer fans is just too noisy. I've disconnected the 3 fans to try and run it passively but it got pretty damn hot. So I drilled a multitude of holes in the top cover above some of the hotter components (PSU and a couple of cooling fins in front) and added a large 120mm fan externally to the top cover above the ventilation holes, this seemed to have brought temps right down on idle (yes I took the top cover off before drilling the vent holes!!).
However in use (i.e when I've connected up several PC's and NAS') its getting hotter on the underside.
Obviously I'd prefer to avoid running the original fans as they're noisy (the 120mm is near silent yet still shifts a large amount of air) but equally I'd rather not come home to a smouldering charred house because the switch has caught fire.
So my question is - what temps do these normally run at and is there a thermal shutdown if they exceed their safe operating temps??
