Hi All; I installed another fan in my computer case. Now it sounds like a Jumbo Jet taking off. I realised that I only need the fan when the weather is hot. I got to wondering if I couldn't install a pot in series with the fan to slow down it's speed and, by turning slower, quiet it down.
Trouble is I don't know what size of pot (in ohms) to put in the line. Any suggestions?
