Question My power supply unit is producing a hissing sound, though the fan isn't working.
Having some noise issues with my Seasonic X series Gold rated PSU. It sounds like a hiss. It comes and goes randomly even when the system is idle. This psu is equipped with a 0 rpm fan feature, and it's for this particular reason that I am certain that it's not fan related. Google search lead me to coil whine, however I'm not sure that's what this is.
I am using passive cooling for cpu and gpu and the rest of the system doesn't even get hot enough to even need case fans. There is only one SSD drive being used so the system is totally silent. The psu is way overkill for what I'm using it for, so by no means placed under any real stress. It is however nearly 10 years old, but used lightly throughout it's life. I have experienced no other issues apart from the noise.
I would rather not replace if there's a simple fix. If anyone can offer some advice or tips I would be grateful.
Thanks.
It's coil whine. Seasonic X-series PSUs are well-known for this issue. Not every X-series experiences it, but many do.
Only a fix is replacing the PSU.
Alternative solutions include boosting the white noise level in your room to mask the PSU coil whine, making it less noticeable (or even inaudible).
Thanks for the update. The system is running at 4770K with a Ge force GT 1030.

If you're confirming the noise definitely originates from your PSU, then I agree. My usual search on "seasonic x series review" indicates that your power supply may only have a seven-year warranty. It looks like you have two options: (1) swap out the unit, or (2) retain it and trust no harm comes to your other PC parts. If I were you, I’d reach out to SeaSonic to check if your PSU is still covered under warranty. They currently offer some models with a twelve-year warranty, which could be a great upgrade. Should it no longer be under warranty, then buying a new one would be the best move.
Regarding your system, it runs a core i7-4770K and GT 1030; both of these support GDDR5 and DDR4 versions of that GPU. It’s realistic for a high-end PSU to exceed the combined value of your CPU and GPU. I’m not trying to provoke, but just want you to be aware of this.

Back in 2012, the Seasonic X-series refresh brought a remarkable 7 years of warranty, which was the longest available at the time. That’s quite impressive, especially when you think about how long that is. Today, most high-quality PSUs come with 10 years of warranty, and Seasonic continues to stand out with their PRIME lineup offering 12 years. Still, 7 years remains a solid amount, particularly when compared to cheaper options like the Corsair CX series, which often only provides 5 years.
