Sorry, I couldn't resist. I don't know the actual fan, but what I do for tube-type stereo stuff (where you don't want to hear the fan) is either choose one with the lowest current draw, or just use a

Thanks for the input. I took the fan out and here's the details; AC fan, 4 5/8" x 4 5/8" x 1 3/8" thick, 5 blades and 100CFM. Mounting holes 4 1/8" apart. It runs full speed all the time. I'll look f

Has anyone had success with noise reduction by replacing the fan on their Centaur?? If so, could you tell us what fan you used and where you found it? 73, de Mike, K9UW ______________________________

There are plenty of computer system cooling fans available that run on 12VDC that have a thermistor so that fan speed (and noise) varies with the temperature (the fan's speed is proportional to the a

Well, I went shopping for a new fan at several of the D/FW electronic stores. I found a number of AC fans that are direct replacements. Some had lower Db and similar CFM specs but, none were quieter.

The best and easiest way to reduce fan noise is to place several dimple diodes in the 13.8v line going to the 12v fan. Use diodes such as 1N4007 (or anything similar). You get about 0.6 to 0.7 volt d

I should have given a little more detail. I tried several resistor values to check perceived noise level and cooling before deciding on the 150 ohm. I am quite happy with the result. It is no louder
