Desktop humming loudly
Desktop humming loudly
Hello there.
I've recently swapped out the front case fans on my PC and have been hearing a really loud hum. I changed them twice—first with Corsair fans, then back to the original ones because the Corsairs caused problems, and finally I replaced them with Cooler Master models. The noise started around the time I swapped the Corsairs in and out. I also updated the rear fan, but left the radiator fans unchanged.
The sound isn’t a buzzing or bubbling; it’s more like a strong idle noise, similar to what most machines make, just amplified. My PC used to have a very low hum before, but it was almost inaudible. The loudness hasn’t stopped even after adjusting the fan speeds and moving the PC around.
When I removed the radiator to get more space, I thought it might be related to the RAM, but even without the fans, the humming continues. I opened the case and used a rolled-up paper to try locating the source, and it seems to be coming from the AIO pump. I didn’t touch the pump during installation, but I wondered if a trapped air bubble could have caused it. I tried running the radiator fans at full speed and adjusting the PC angle, but it didn’t help much.
The machine is otherwise fine, except for this persistent loud noise. I can hear it humming while standing outside my room, with my desk on the opposite side by the wall. As someone sensitive to sound, it’s really distracting without headphones—I can’t relax without worrying something’s wrong. There’s no shaking or vibration, just a steady hum.
I’ve tried reseating the radiator and even switched to a different GPU bracket, but I’m still unsure. It might be the AIO pump. When I placed my ear near the top of the case, the noise was louder right above the CPU. I’m stuck and not sure what to do next—maybe try repairing it or taking it to a shop for help.
Here are my details:
Case: Cooler Master Masterbox TD500 Mesh
Front fans: Cooler Master Mobius 120P x3
Rear fan: Corsair AF120 Elite x1
Motherboard: ASUS Rog Strix B550-F Gaming
CPU: AMD Ryzen 7 5800X3D
Cooler: Corsair iCUE H150i Elite
Radiator fans: Corsair AF120 Elite x3
GPU: Palit GeForce RTX 3080
RAM: 32GB Corsair Vengeance Pro (2 x 16GB)
SSDs: 1x 500GB Samsung 980 Pro, 1x 2TB Samsung 980 Pro
Power supply: Corsair 1000W RMx Series Modular 80 Plus Gold
Operating system: Windows 11
Monitor: Samsung Odyssey G7
Any suggestions would be really appreciated. Thanks.
Hi there, yes, plus the three in my GPU.
I've used the fan control software and managed to shut off the fans entirely. Still, the loud humming remains even when all fans are at 0 RPM. I'm starting to wonder if it's not a fan.
Use the paper tube once more to gently check the area within the case for the noise origin. Is there a built-in speaker?
Acoustics maybe. Resonance might be involved.
Power off, unplug the machine, detach the speaker.
Restart and check once more if the noise persists. Continue probing for its origin.
If it remains elusive, examine everything closely...
Reminder:

Search for coils and capacitors, particularly any with glue residue.
Check for swelling, leaks, or structural damage.
Loose or missing screws, bent or cracked components.
A bright flashlight can be useful.
Not a simple inquiry at all.
The drive cage might have offered physical stability and/or reduced sound that hid or blocked the hum.
Reinstall the drive cage—just to rule it out.
Also remember that later you might wish to incorporate a drive.
Affordable adapters exist to fit an SSD into a HDD cage.
This will also confirm the exact location of the drive cage.
Okdokes appreciates your assistance and will verify it again. Cheers.
