I did this to a Cisco/Linksys 2008 switch using a 5V 3-wire voltage regulator to bring the tiny fan's speed down from howling loud to quiet enough for desktop use. Only then did I discover that the box was so electrically noisy that it wiped out the local AM NPR station.
Anyone looking for an acoustically quiet 8 port POE gigabit switch who does not listen to weak AM radio signals can contact me off-line :-] Vince On Wed, 2014-12-17 at 12:02 -0500, chris wrote: > Hello, > > Has anyone on the list ever messed putting in a fan controller in a switch > so its inline between the motherboard and fan?
