P4 chip makes too much noise - Page 6

biCker · 24th June 2004, 22:22

the grounding (house, wall pluggs and case are ok, it was tested not so long ago (renovating this damned place

)

anyway, I tried to record the hissing butt my headset mic isn't good enough, the only thing you can hear is a "cricket" like sound when I'm scrolling. turn your speaker volume all the way up, else you wont hear a thing...

sound

First of all, the woman you mentioned might have terminal MPS on a monthly basis.

Secondly, if you have to turn the speaker all the way up to hear; it may well be the sound system rather than the processor itself. Unplug all audio related components, i.e. including disable onboard sound, let me know if the hisses still there.

woman? mps?

I meant you have to turn your speakers up to be able to make something out of the soundfile in the link

Now I got it; the sound file!!; )

What do women produce on a monthly basis?

The only place (hardware) that may produce "hisses" or "sound waves" would be from:

1) Power Supply
2) On board capacitors

Most EMI comes from bad power supply. But, that is an old song. Today, EMI is rare occurance. The same reason you are finding clear plexi case and window case. Full metal case prevents EMI better.

EMI = interference? like a cellphone lying close to the pc so that one can predict an incoming call seconds before the phone actually starts to ring?

Today all equipment should be shielded well enough to prevent that.

i'm certain the sound comes from the cpu btw -> I switched my 2.4 by a 2.26 and the hissing was no more, I switched again and ... indeed :grum:

Electro-Magnetic-Interference = EMI

There is harmonic interference, which has to do with frequency wave length; similar to TV reception "ghost".

so the full metal case has something to do with the "kooi van Faraday" (don't know the translation for that, can someone help me out?)

I have a P4 2.53b @ TerAngreal which I could switch with yours if you want...

Thanks for the offer but I kind of ruined the warranty this afternoon: I took of the hsp and lapped it while I was at it.

I'm going to build a "kids entertainment system" around this cpu, as if they care about a little noise more or less
