I see in the other comments that you have sidetone disabled in the OS. Are you certain you didn’t install any software when using the headset? If so, could you try using the headset with another pc or your phone and see if it still happens?

Did you install anything to use them? If so, perhaps the turtle beach software has a setting for this. If not, which OS are you on? Windows 10? 11? Linux?

There’re a few things that can cause this. The headphones themselves may have a feature that enables it which you should be able to disable. Otherwise, you may have it configured in your os.

Which headphones and os are you using?

I’m just repeating what many others have already said, but for this setup you really don’t need a liquid cooler. A simple air cooler would more than suffice and would save you like $100-$120. Additionally, it looks like you’re paying a premium for an SFX power supply when an ATX power supply would fit. SFX power supplies are super cool in that they can pack so much power in a tiny size. But you wouldn’t benefit from that in this case.

After changing the above, perhaps you could then fit a decent GPU into your budget.

Oh interesting, that seems like a pretty bad problem that should be sorted out. Seems like fhe spoiler tag is effectively useless if it just doesn’t work for half of us.

Your spoiler tag isn’t working. If you actually cared, please fix it.
