Whining Components cured with wax?
I saw over at phoronix.com that they modded an old PSU and among other things silenced components by melting wax on them. Anyone else tried this?
Quote from the article:
Next problem we faced was the humming noise. The only possible cause for this noise would be an old worn out inductor. Therefore, we proceeded to flood both main inductors with candle wax. This un-scented wax had been ordered from a candle shop for just a few bucks and then melted with a stove. After doing so, the noise hadn't died out as we had expected. Later on we found a small inductor taped to a little transformer (for transfer of magnetic flux, but a very dodgy technique). We flooded this trivial inductor with wax and whalla! The noise was now gone.[/url]

Please use electricians goop (the yellow crap you see inside PSUs) or better yet acid free RTV silicone (the GE silicone stuff has acetic acid iirc). I believe they sell silicone for electronic devices since the regular stuff might corrode the thin insulator on the coils.
Wax is scary. Glue and thermal paste sounds promising.

I think some people might have actually done so with earplugs, (foam ones IIRC). I'm thinking of trying it with a portion of a thermal pad, but I'd have to find a place that sells them.zoob wrote:Has anyone ever successfully silenced a whining coil with electricians goop or silicone? I've seen posts about people wanting to do it, but to my knowledge no one has reported back :\
Edit: I think it wouldn't be neccesary to entirely cover a coil in glue or whatever, only a few small blobs of it sticking the coils together should be needed.
I thought it's more for keeping water condensation off the coils?silencery wrote:some electric components come w/ a thick grease to cover the coils. I'm assuming its to serve the purpose described here.
Phonics. The same reason they keep referring to the "3 Rs of education".silencery wrote:Why do people constantly spell it whalla? What the heck is whalla?
