That buzzing sound coming from your PC is probably not the start of a hardware meltdown. Most GPU buzzing noise cases I deal with are either coil whine (harmless but annoying) or a fan clogged with dust (easy to fix). Before you start pricing up a new graphics card or booking a repair, spend ten minutes working through the checks below. Odds are you will sort it without spending a penny.

TL;DR

GPU buzzing noise is usually coil whine from power delivery components vibrating under load, or a fan issue from dust or cable interference. Cap your frame rate first, then clean the fans, adjust the fan curve, and undervolt the GPU if the noise persists. Only consider hardware changes like PSU upgrades or thermal paste replacement if the basic fixes do not help.

What Causes GPU Buzzing Noise?

The first thing to figure out is what kind of noise you are actually dealing with. Not all GPU buzzing noise is the same, and the fix depends entirely on the cause. I have seen people replace perfectly good fans when the real culprit was a daisy-chained power cable, so it is worth spending two minutes on diagnosis before touching anything.

The most common cause is coil whine. Inside your GPU's power delivery circuitry are tiny inductors (coils) that regulate voltage. Under high electrical load, these coils vibrate at frequencies in the audible range, producing a whine or buzz. It is worst when the GPU is pushing very high frame rates because that means more rapid power switching. If your buzzing is loudest at game menus or when your frame rate is uncapped and hitting 300+ FPS, coil whine is almost certainly what you are hearing. According to Tom's Hardware's GPU coverage, coil whine severity varies significantly between GPU models and even between individual units of the same model.

The second major cause is fan noise. Dust buildup on fan blades and heatsink fins forces fans to spin faster to shift the same amount of heat, which creates more noise. Worn fan bearings produce a grinding or rattling sound that gets worse over time. And a loose cable that has drifted close to a spinning fan will create an intermittent buzzing or clicking that sounds alarming but takes about 30 seconds to fix once you spot it.

Overheating is closely related. If thermal paste has dried out (common on cards that are three or more years old), the GPU runs hotter than it should, the fans ramp up aggressively, and you get a lot of fan noise on top of any coil whine. The two problems compound each other.

Finally, PSU quality and cabling matter more than most people realise. A budget PSU with poor voltage regulation delivers noisier power to the GPU, which aggravates coil whine. Daisy-chaining two GPU power connectors off one cable (common with cheaper PSUs that do not include enough cables) creates voltage instability under load. And if you have overclocked the GPU, that increases power draw and makes all of the above worse.

GPU Buzzing Noise: Quick Fixes (5 to 10 Minutes)

Start here. These require no tools and no opening of the case. A significant number of GPU buzzing noise complaints I see are fully sorted at this stage.

Cap Your Frame Rate Easy

Open your game's graphics settings
Look for a frame rate cap, max FPS, or vertical sync option. Set a cap at 60, 144, or whatever matches your monitor's refresh rate.
Alternatively, use your GPU driver
In NVIDIA Control Panel, go to Manage 3D Settings and set Max Frame Rate globally. In AMD Adrenalin, find the Radeon Chill or frame rate target control under Gaming settings.
Test immediately
Launch the game and listen. Coil whine from GPU buzzing noise typically drops in pitch and volume within seconds of the cap taking effect. If it does, you have confirmed coil whine as the cause.

Buzzing reduced or gone after capping FPS? Coil whine confirmed. Keep the cap in place as your permanent fix.

Lower Graphics Quality Settings Easy

Reduce your graphics preset
Drop from Ultra to High or Medium. Disable ray tracing and supersampling (DLSS Quality mode is fine, but Ultra Performance pushes the GPU harder). This cuts power draw and reduces both coil whine and fan noise.
Check the result
If the GPU buzzing noise drops noticeably with lower settings, power draw is the driver. Combine this with a frame rate cap for best results.

This is not a permanent fix for everyone, but it is a useful diagnostic step. If noise disappears at Medium settings, you know the GPU is being pushed hard at Ultra and the coil whine is load-dependent.

Intermediate GPU Buzzing Noise Fixes (15 to 30 Minutes)

If the quick fixes did not fully sort it, or if the noise sounds more mechanical (grinding, rattling, clicking) rather than electrical (whining, buzzing), you need to get inside the case. These steps cover the most common physical causes of GPU buzzing noise.

Clean GPU Fans and Check Cable Routing Easy

Power down properly
Shut down Windows, flip the PSU switch to off, and unplug the power cable from the wall. Wait 30 seconds before opening the case.
Check for cables near fans
Look at the GPU and the area directly around it. Any cable that has drifted close to a fan blade will cause intermittent buzzing or clicking. Re-route offending cables and secure them with cable ties well away from any moving parts.
Clean with compressed air
Use short bursts of compressed air to blow dust out of GPU fans and heatsink fins. Hold the fans still while blasting them so they do not over-spin. Also clean case intake and exhaust fans while you are in there, because poor case airflow forces the GPU to work harder.
Spin fans by hand
Gently flick each GPU fan blade and let it spin freely. All fans should spin smoothly and stop gradually. If one resists, wobbles, or sounds gritty compared to the others, the bearing is worn and that fan needs replacing.
Reassemble and test
Put the side panel back, power up, and run a game for 15 minutes. A lot of GPU buzzing noise from mechanical causes is gone at this point.

Fan noise reduced after cleaning? Dust buildup was forcing the fans to work harder than needed. Schedule a clean every three to six months going forward.

Adjust GPU Fan Curve in MSI Afterburner Medium

Download and install MSI Afterburner
Get it from the official MSI site or TechPowerUp's Afterburner coverage for the verified download link. It works with NVIDIA and AMD cards regardless of brand.
Open fan control settings
Click the Settings (gear) icon, then go to the Fan tab. Tick the box labelled Enable user-defined software automatic fan control.
Edit the fan curve
The curve shows fan speed percentage against temperature. Drag the mid-range points (around 60 to 75 degrees Celsius) slightly downward to reduce fan speed at those temperatures. Do not go below 40% at high temps; you need airflow. Keep the GPU under 85 degrees Celsius under full load.
Apply and test under load
Click Apply, then run a game or benchmark for 20 minutes. Watch the GPU temperature in the Afterburner overlay. Find the point where noise drops without temps climbing too high.

Do not set fan speeds too low if your GPU is already running hot. Thermal throttling is worse than a bit of fan noise. Keep an eye on temperatures with HWInfo during testing.

Clean Driver Install via DDU Medium

This one is specifically for cases where the GPU buzzing noise accompanies a PC freeze or audio lockup, not for pure coil whine. If your PC stutters or locks up and the audio produces a buzzing loop at the same time, a corrupted or incompatible driver is often the cause. You can read more about display driver issues in our GPU driver crash fix guide.

Download DDU (Display Driver Uninstaller)
Get it from Wagnardsoft. Boot into Safe Mode (hold Shift and click Restart, then go to Troubleshoot > Advanced Options > Startup Settings > Restart > press 4).
Run DDU in Safe Mode
Select your GPU manufacturer (NVIDIA or AMD) and click Clean and Restart. This removes all driver files cleanly.
Install the latest driver
Boot normally, go to the NVIDIA or AMD website, and download the current Game Ready or Adrenalin driver. Install it fresh. If you have had persistent freeze-related buzzing, also try disabling Hardware-Accelerated GPU Scheduling via Settings > System > Display > Graphics > Default Graphics Settings.

If freeze-related GPU buzzing noise stops after a clean driver install, a corrupted driver was the culprit. Keep drivers updated but do not chase every release; wait a week or two after a new driver drops to let others report issues first.

Advanced GPU Buzzing Noise Fixes (30+ Minutes)

These are for persistent cases where the quick and intermediate steps have not fully resolved the GPU buzzing noise. Undervolting in particular is something I recommend to almost everyone with a modern NVIDIA or AMD card because it reduces noise, heat, and power consumption with very little downside. Thermal paste replacement is more involved but makes a real difference on older cards.

Some steps below involve opening the GPU cooler or adjusting voltage. Follow your GPU manufacturer's documentation carefully. If you are not comfortable with any of these steps, our remote support team can walk you through the software-based fixes (undervolting, fan curves, driver settings) live on screen.

Undervolt the GPU Medium

Undervolting is the most effective software fix for coil whine. You are telling the GPU to run at a lower voltage for the same (or similar) clock speed, which reduces power draw and the electrical noise that causes GPU buzzing noise. It does not damage the card. I have done this on dozens of RTX 3000 and 4000 series cards and it consistently reduces coil whine by a noticeable amount.

Reset any existing overclock first
If you have overclocked the GPU, revert to stock settings in Afterburner or your vendor's software. Overclocking makes coil whine worse by increasing voltage and power draw.
Open the voltage/frequency curve editor in Afterburner
Press Ctrl+F in Afterburner to open the curve editor. You will see a graph of voltage (x-axis) against clock speed (y-axis).
Set a lower voltage point
Find the highest clock speed point on the curve (typically around 1900 to 2100 MHz on RTX 40-series cards). Click the point at a lower voltage (for example 0.862V instead of 1.0V) and drag it up to match that same maximum clock speed. Then select all points to the right of it and drag them down so the curve does not exceed that voltage.
Apply and test stability
Click Apply (the tick icon) in Afterburner. Run a demanding benchmark like 3DMark Time Spy or Unigine Superposition for 20 minutes. If the system crashes or you see visual artefacts, increase the voltage point slightly and test again.
Verify noise reduction
With a stable undervolt, the GPU buzzing noise should be noticeably quieter. Temperatures will also drop a few degrees, meaning fans run slower too.

A successful undervolt typically reduces coil whine by 30 to 60% in my experience. Some cards go near-silent. Others improve but do not disappear entirely, which is down to the card's design.

Fix PSU Cabling and Consider a PSU Upgrade Medium

A dodgy power supply or a daisy-chained PCIe cable can make GPU buzzing noise significantly worse. This is especially true if the buzzing started after you upgraded to a more powerful GPU without upgrading the PSU at the same time.

Check your PCIe cables
Open the case and trace the power cables from the GPU back to the PSU. If two GPU power connectors share a single cable from the PSU (daisy-chained), that is a problem. Each GPU power socket should have its own dedicated cable running directly to the PSU.
Swap to dedicated cables
If your PSU has enough spare cables, swap to individual runs. If it does not, that is a sign the PSU is undersized or under-specified for your GPU.
Assess PSU quality
Budget PSUs with 80 Plus Bronze ratings or no rating often have poor voltage regulation and high ripple, which feeds noisy power to the GPU. If the PSU is a no-name unit or came bundled with a cheap case, it is worth replacing. Look for 80 Plus Platinum or Titanium rated units from Seasonic, Corsair RMx series, or be quiet! Straight Power. These have tighter voltage regulation and genuinely do reduce electrical noise in some setups.

PSU wattage is not the main factor here. A 650W Platinum PSU will typically deliver cleaner power than a 850W Bronze unit. Focus on efficiency rating and brand reputation, not just the watt number on the label.

Replace Thermal Paste Advanced

If your GPU is three or more years old and running hot (regularly above 85 degrees Celsius under load) with fans at maximum speed, dried-out thermal paste is likely making the noise worse. Better cooling means lower fan speeds and less GPU buzzing noise overall. This is also worth doing if you have already cleaned the fans and the card still runs hot. For more on keeping hardware running cool long-term, see our PC overheating fix guide.

Remove the GPU from the motherboard
Power down, unplug, remove the GPU, and place it on a clean, static-safe surface.
Disassemble the cooler
Unscrew the heatsink following your GPU model's specific teardown guide (YouTube has good model-specific videos for most cards). Keep screws organised.
Clean old paste
Use a lint-free cloth with isopropyl alcohol (90% or higher) to clean the GPU die and heatsink contact plate until both surfaces are clean and dry.
Apply fresh paste and reassemble
Apply a small pea-sized amount of quality thermal compound (Thermal Grizzly Kryonaut or similar) to the GPU die. Reattach the heatsink, tighten screws in a cross pattern, and reassemble the card.
Reinstall and test
Reinstall the GPU, boot up, and run a benchmark. Compare temperatures to before. A 10 to 20 degree Celsius drop is common on older cards with degraded paste.

Thermal paste replacement voids some GPU warranties. Check your card's warranty status before proceeding. If the card is still under warranty and running hot, contact the manufacturer first.

When It Is a Freeze Plus Buzzing Audio Problem

Some people come to me describing GPU buzzing noise that is actually the audio system looping when the PC freezes. This is a different problem. The buzzing is not from the GPU hardware itself but from the audio driver repeating its last buffer when the system hangs. If your PC freezes and you hear a repeating buzz or drone until you force-restart, check the following.

First, use HWInfo to monitor CPU and GPU temperatures under load. If either is hitting 90 degrees Celsius or above, thermal throttling may be causing the freeze. Second, run Windows Memory Diagnostic (search for it in the Start menu) or MemTest86 overnight to rule out RAM errors. Third, open Event Viewer (Win + X, then Event Viewer) and look under Windows Logs > System for Kernel-Power event ID 41 around the time of the freeze. That event confirms an unexpected shutdown and gives you a starting point for further diagnosis. You can find more detail on this in our PC freezing and crashing fix guide. Disabling Game Mode and Hardware-Accelerated GPU Scheduling (Settings > System > Display > Graphics > Default Graphics Settings) also resolves this in a surprising number of cases.

Preventing GPU Buzzing Noise

Most GPU buzzing noise problems are avoidable with a few basic habits. Here is what actually makes a difference, in order of importance.

1. Use a quality PSU from the start. This is the single biggest factor people overlook. A PSU with 80 Plus Platinum or Titanium certification and good voltage regulation (Seasonic, Corsair RMx, be quiet! Straight Power) feeds cleaner power to the GPU and reduces coil whine. Always run dedicated PCIe cables to each GPU power connector, never daisy-chain them.

2. Set a frame rate cap as standard practice. There is no reason to run at 400 FPS in a game your monitor displays at 144 Hz. Cap the frame rate in-game or via the driver. Your GPU runs cooler, quieter, and the coil whine is reduced. It is a free win.

3. Clean the GPU every three to six months. Dust is the enemy of quiet operation. A five-minute clean with compressed air keeps fans running at lower speeds and prevents the thermal buildup that forces aggressive fan ramping.

4. Do not overclock unless you have a specific reason. Overclocking increases voltage, power draw, heat, and coil whine. If you want more performance with less noise, try undervolting instead. It often gives you similar performance to a mild overclock with noticeably less GPU buzzing noise.

5. Keep drivers reasonably current. You do not need to install every driver the day it drops, but staying within a few versions of the latest release avoids the stability issues that cause freeze-related audio buzzing.

GPU Buzzing Noise: Summary

GPU buzzing noise is almost always one of two things: coil whine from power delivery components vibrating under load, or a mechanical fan issue from dust, worn bearings, or cable interference. Start with a frame rate cap and graphics quality reduction. If that does not fix it, clean the fans and check cable routing. For persistent coil whine, undervolting the GPU is the most effective software fix available and it is safe to do on any modern NVIDIA or AMD card. PSU quality and cabling matter more than most people expect. And if the buzzing only happens when the PC freezes, that is a driver or stability problem, not a GPU hardware fault. Work through the tiers above and the GPU buzzing noise should be sorted without needing to replace anything.
