Tips for handling subtle noise in your new PC setup
Hello! Your new PC setup seems to be functioning well overall. The faint continuous high-pitched noise you mentioned is unusual and could be worth investigating further. It doesn’t match typical coil whine, which usually has a buzzing quality, but it does resemble some media depictions of tinnitus or ringing in the ears. Since the noise isn’t changing with load and is barely noticeable except in silence, it might originate from the power supply unit or the motherboard. The PSU model you have (RM750x) makes pinpointing the source a bit tricky. Have you heard similar sounds before? It’s not uncommon for modern PCs to produce such subtle noises, but if it persists or affects your experience, it might be worth checking those components. Your experience is valuable—thanks for sharing!
It seems like typical coil whine is present. Are you using an AIO? Check your ears near the back of the PSU—if the noise comes from there, it’s likely coming from the power supply unit. I noticed my RM750i had this consistent whine even when idle, only noticeable close to the PSU. Both the RM750i and x models use the same parts.
It seems like you're noticing a faint hum coming from the PSU exhaust when you place your ear nearby. That kind of sound can be tricky to pinpoint. It appears to spread through the air, making it noticeable even in quiet spaces. I’m curious if this is unique to your setup or common across similar models. If it’s likely from the power supply unit, replacing it might resolve the issue. Otherwise, testing other components could help identify the source.
I get what you’re talking about regarding the difficulty in pinpointing the sound. For me, dealing with misophonia and hyperacusis made it much simpler. I could only notice it in a completely quiet environment. If the issue is coming from the power supply unit, it’s likely just normal coil whine that PSUs, GPUs, monitors, and similar components can produce. It’s not harmful or dangerous, and it doesn’t impact the product’s lifespan. The audio file you shared didn’t contain anything concerning or alarming. My PSU would show minor coil whine even when the computer was powered off but connected to power. Since you find it hard to identify the noise, you may need to try moving the PSU outside the case to better assess its source.
I understand! This kind of sound usually happens only when the PC is powered on. It’s completely quiet when the system is off or in sleep mode. If you have more time, you might want to investigate its source. As for whether it’s common, yes, some PSUs can make such noises.
The outcome of the PSU selection was quite random. One PSU worked only with one particular motherboard and even affected the CPU voltage regulators, while another compatible motherboard showed no issues. Meanwhile, my multiple NVIDIA GPUs consistently produced a whining sound.
