Is it normal for coil whine to come through headphones?

My PC has had very loud coil whine since March. I usually don't use my headphones in the ports on the case but on the motherboad, but today I did use them on my case and I heard the coil whine come through it. I know this wasn't the case when I first built my PC (it also didn't whine at that time). Does that tell me anything about what part could be causing it? All I know is it's not the PSU

This stuff always was black magic to me, it could be grounding issues, electrical wiring issues, shielding issues, a bad capacitor - who knows.  If this just started, I would start looking over your capacitors on the board and see if any of their tops are starting to dome out - they should be completely flat.  If you find any, they will need to be replaced.

 

If all looks good, then no telling.  A solution that should work is an external USB DAC.  Good luck!

Analogue audio easily picks up interference. Some PCs are crystal clear, some are noisier.  The PC I'm on right now, you'll hear noise on the front audio jacks through the header, maybe cause that wire is going through the case along other wires including power, but the rear jacks are fine.  I once had a PC where, with headphones, I could hear a faint noise every time the HDD light was lit up.

All capacitors look good to me. Also I have replaced the motherboard and GPU before. GPU made a difference in the sound but not in a good way, motherboard made no difference.

Then I would proceed to an external DAC.  This is the stuff that drives audio engineers mad.

I got amazingly clear results on my Sound Blaster AE-7. ...It also set me back CAD$300, but damn that built in headphone amp?  Drives those headphones real nice.

That's not really coil whine if it's over headphones, it's usually a ground loop, or just a low SnR sound card. Before I bought my SBZ card my PC would audibly hum through speakers/headphones on the crappy integrated sound but a better sound card fixed it.

Yep. 

 

Is it plugged in? Is it turned on? Are you sure? No, really.

Could be that too. 

 

Did you try another Psu?

 

 

I have a Sony tape deck that I've been trying to fix, does exactly what OP described. Hum on headphones, not in recordings or anything. Something between the source and your ears - probably a ground issue if it's that.

Completely normal for the front audio port to have this issue. Either try shielding the audio cable which goes to the front of the cases yourself with some aluminium tape and grounding wire or just use the read IO of the mainboard.

Yes, I replaced pretty much everything (PSU 3 times). If you're interested here's a timeline:

March/April: issue started

June: RMA'd GPU - got different GPU to borrow which also whined

Also June: RMA'd PSU (System Power 9 600w)

July: Received new GPU. Found RM650x for cheap so also bought that - Coil whine even worse than before

July: Received new PSU from RMA - No difference

August: Replaced motherboard - Same model, no difference

Yep. 

It is coil whine, I can hear it coming from the GPU and motherboard VRM. It's pretty loud and even audible when doing something as simple as scrolling or moving the cursor. It just seems to go through the front jack as well.

Could try that, seems like that can help

 

Also I do have the cheapest case I could find (Antec DP301M), is that a problem?

No. Those wires are always unshielded for some reason. Just using the rear mainboard IO is the best workaround. If you can't reach easily there buy an simple (unshielded) extension cable. It will be fine as the distance between components like GPU, PSU, etc. is larger.

Headphones which are harder to drive are also a option but I guess you don't want to replace them.

That's how I usually have it. My headset came with a long cable that splits the 3.5 into a seperate cable for input and output, which I usually have in the rear IO under my desk.
