I bought a small cooling fan at Radio Shack to cool down some of my stereo components, but when I hooked it up it was louder than I had expected. I was about to return it and look for a quieter unit, but before doing that I thought I’d check with my friends here at the Dope.
Is there a simple way to slow it down? It’s a 115VAC, 130 mA fan, and I think it would probably provide adequate cooling at half its rated speed (3,100 rpm), and obviously be less noisy.
Can I wire in a resistor or something? If so, what specs, and how do I wire it? Or should I just spring for a quieter unit like this one? The one I have has a rated noise level of 36dB.)
