Last week I swapped my Noctua NH-D15 CB for a NH-U12A CB because of size preferences for my ASUS X570 TUF GAMING PLUS. During installation, the mounting points made slight contact with those black cylinders and capacitors on the motherboard surrounding the CPU. Now the board produces faint, steady electrical sounds occasionally. I’ve observed that: - The GPU, GIGABYTE RTX 4070 Super, emits a quiet yet noticeable noise from its LED (I’ve tried disabling it through GIGABYTE’s app, but it persists without any other sound). - When the tower is placed flat, this noise becomes less audible, and the GPU stays securely fastened. - The speakers, CREATIVE PEBBLE V3, make a faint hissing sound when connected via USB C directly to the board at any volume. No other devices like the keyboard (USB A) or monitor seem affected. Could it be that the motherboard’s sounds are influencing nearby components?
That’s quite a detailed observation, buddy. You’re pretty sure this coil whine isn’t new, are you? I don’t think a buzzing microcontroller could be the source, but it’s possible something in the PSU or even the wall power is causing the issue. It’s also possible everything’s vibrating at the same frequency and you’re just having a hard time pinpointing it. Try using a phone app that shows audio spectrum to move around the case—maybe you’ll spot the exact spot where the noise comes from.
(The following's a copy/paste from another forum) A few days ago i placed the old cooler, Noctua NH-D15 CB, and the noise is there too. Again, with the previous cooler, before this changfe, this NEVER happened Yes, i've made sure that when screwing the cooler in again i held the backplate with a hand so that the bolts were tightly screwed (without overdoing it) while the plate remains attached there to prevent having a "separation" with the motherboard (Leading to vibrations) And when installing the cooler itself (Not the holding mounts) i followed the instructions of "Do 2-3 spins on one bolt, then move to the next one. Rinse and repeat till it's tightly mounted" However i gotta add that sometimes the mount holders were dancing around and LIGHTLY hit some of the black capacitors that surrounds the CPU. Not sure if this is the reason or the PSU is starting to lose power or have coil whine there that might affect the other components, and it's just nearly 3 years old... And that the baseplate on the new one had a tiny scratch but it was smooth and soft without any bumpings. People said that thermal paste "fills it up". Temps stays at 33-34C on IDLE with STEAM off (STEAM likes to mess things up, but even worse Microsoft Edge tasks even tho i don't use the app but i need the app to make other apps to work, sadly) This is a vid of the actual cooler. Rise the volume to the max as it's hard to hear PC: Be Quiet! DARK BASE PRO 901 CORSAIR RM1200x SHIFT (European cable) ASUS X570 TUF GAMING PLUS RYZEN 5800X3D Noctua NH-U12A Chromax Black GIGABYTE RTX 4070 Super 2 SATA SSDs, 1 SATA HDD, 1 SATA DVD drive HDD has been disconnected because it'd interfere with it's own noise While i can hear the noises the phone doesn't catches em sometimes (mostly the CPU fans), at 0:59 it should be hearable from behind the CPU's mounting plate. Noises that i am hearing are: -Motherboard: Front: Around the cooler. Rear: More heard at 0:59 behind the mounting plate, same area as the front. -GPU: While it's not "heard", if i put my left ear at the GIGABYTE RGB logo my left ear can hear/feel an "intensification" in that area. Rest of the GPU (ports, heatsink by the left and center , and PSU cable) are not heard on both ears. If i disable the RGB with GIGABYTE's app the noise remains there. If i unplug the GPU from the PCI port the sound's gone (But i need the GPU...) -PSU: It does a soft and faint sssssss like if it was an electrical version of an HDD spinning. After a few seconds it stops but it returns 3-5 seconds after -HDD: While it doesn't shows connected in the vid to isolate the noises some, this one, a WD Blue SATA HDD 4TB has like 3 noises: Spinning (Acceptable), chirping and a kind of ssssssss like the PSU does. Not sure if the PSU has something to do with it What i want to know is why these noises are happening and how i can silence them. No, i do not have people to change parts to test things out with so it's all about buying new hardware and try out one by one Reason i'm asking this is because i have tinnitus and i want to prevent ASAP that these noises gets recorded in my ears FOREVER, and while some are temporal, others aren't... And that i want my PC to stay silent again (Within the fans' noise). I already seem to have that intense GPU "silent noise" in my left ear and it's not going to leave at all. It sounds like a "Riii-iiiing...Riiii-iiiiing....". I used OCCT and it comes from it. The GPU yesterday might've done an enormous "Woooo wooooo" electrical wave through the room that lasted a couple of minutes but it was on IDLE EDIT: Audio Spectrum by SpecStream app. Hopefully these helps (3 images in the link!. First one PSU, 2nd GPU, 3rd CPU's left side above GPU (Has rear fan noise but blocked the only working cooler fan) https://imgur.com/gallery/audio-spectrum-m39hcfv
