Electrical Feedback/Noise - xspc 750 Pump

post #1 of 4
Thread Starter 
Noticed some crazy noise people were complaining about in teamspeak and with some quick testing found that I transmit this noise even with the mic unplugged. 10 mins of pulling random cables later I kill the pump and the noise is gone.

I mean the pump doesnt sound great, but its not noisy and my temps are fine.

What part of it could be causing electical feedback into my PSU like this. Happens regardless of the rail it is on.

Oh and I think my HDD just died too... Happy Friday.

I get this with my 470(s) installed. Try keeping the power cable for the pump/ the pump itself away from your soundcard. With my PC I get the noise with my i3 board & audio, Q6600, different board & audio and my pentium D 830 with a third board. I use the audio in and out on my G510 keyboard, I think the fact that it's external keeps it away from the source of interference.

Edit: obviously I get it because my card is what's causing it and it's very close to the sound circuitry on each board. I'm guessing if it is the pump keeping the cable and pump away from your soundcard should help if nothing else

not an unshielded cable, the xonar stx is shielded from em. its literally feeding back into the PSU.

Sorry, didn't read properly I guess That's really weird :/ Since I can't help, I'm sure you've googled already but there's a couple of links here if they help.

Edit: They mention shielding the pump which would make sense but if it's the PSU itself I don't know if that'd help. You could always try taking a metal plate and moving it around to see where it's coming from or something.
