You hear a high-pitched buzz or squeal from your PC, loudest in game menus or loading screens, and the fans don’t seem to be the cause.

You can often make it much quieter.
Quick fix
Try these in order:
- Make sure it’s coil whine, not the fans. Coil whine changes with the frame rateFPS (frames per second): How many pictures per second the PC draws in a game. More is smoother; around 60 or more feels fluid. More in our Windows & performance glossary →, not the fan speed. How to tell.
- Cap your frame rate a little below your monitor’s refresh rateRefresh rate (Hz): How many times per second the monitor updates the picture, for example 60 Hz or 144 Hz.

- Lower the card’s power with an undervolt or a lower power limit. See the steps.
- Check it isn’t the power supplyPSU (power supply): The power supply: the box that takes power from the wall and feeds every part through cables. More in our PC basics glossary →, especially if you hear it at idle or with the PC switched off. See the steps.

Why coil whine happens
A graphics card is full of small coils, also called chokes or inductors, that smooth out its power supply. When the current through them changes very quickly, they vibrate slightly, like a tiny loudspeaker. Usually that vibration is too high-pitched to hear. When the card is working hard and fast, especially at very high frame rates, it can become audible.
It varies a lot from card to card, even between two cards of the same model, and it can depend on the power supply too. A whine doesn’t mean the card is faulty or will fail.
| When you hear it | What it means | Where to look |
|---|---|---|
| The noise is loudest in menus, loading screens or old games. | Very high frame rates | Step 2 |
| The noise appears under heavy load in demanding games. | High power draw | Steps 2 and 3 |
| The noise appears at idle, or with the PC off but plugged in. | Probably the power supply, not the card | Step 4 |

1. Make sure it is coil whine
Fan noise or coil whine?
They sound different and have different fixes. Listen for these clues.
Fan noise
- A rushing "whoosh" of air
- Gets louder slowly as the card heats up
- Stays the same when you pause or open a menu
- Changes when you change the fan speed
Coil whine
- A high-pitched buzz, squeal or "electric" chirp
- Starts instantly when a game or menu loads
- Rises and falls with the frame rate
- Stays the same at any fan speed
Still unsure? With the side panel off, move your ear (not your hand) close to the graphics card, then the power supply. Coil whine comes from a fixed spot.
How to check: start a game and pause it, or open its menu. If the buzz changes pitch or jumps in volume the moment the frame rate changes, it’s coil whine. If you have MSI Afterburner, set the fans to a fixed speed for a minute: fan noise changes, coil whine doesn’t.
2. Cap the frame rate
This is the single most effective fix. Most coil whine comes from the card racing to make hundreds of frames per second, often in menus or loading screens where you don’t need them. A frame rate capFrame rate cap (FPS limit): A setting that stops the graphics card making more frames per second than you choose, so it works less hard. More in our Graphics cards & display glossary → stops that.
Fix: set a cap a few frames below your monitor’s refresh rate, for example 141 FPS on a 144 Hz screen, or 58 on a 60 Hz screen.
- NVIDIA: NVIDIA Control Panel → Manage 3D settings → Max Frame Rate. This applies to every game.
- AMD: AMD Software (Adrenalin) → Gaming → Graphics → Frame Rate Target Control, or turn on Radeon Chill.
- In the game: most games also have a frame limit or V-Sync setting in their video options.
A cap also makes the card cooler and quieter, so it’s worth keeping even if the whine doesn’t fully go away.
3. Lower the power the card draws
The more power the card pulls, the more the coils can sing. UndervoltingUndervolting: Running a chip at slightly lower voltage so it makes less heat and noise, often with no loss of speed. More in our Cooling & noise glossary →, or simply lowering the power limit in MSI Afterburner by 10–20%, often makes coil whine quieter with only a small loss of speed. Our guide to a loud graphics card fan introduces undervolting. As a bonus, the card also runs cooler: see how hot a graphics card should run.
4. Check whether it is the power supply
The power supply has coils too, and it can whine on its own or together with the card. Clues that it’s the power supply:
- You hear it at idle on the desktop, or even with the PC switched off but still plugged in.
- With the side panel off, the sound clearly comes from the bottom or back of the case, where the power supply sits.
Fix: try the PC on a different wall socket, without a power strip. If the whine comes from the power supply itself, contact its maker under warranty. Our guide to power supply noises explains which ones are harmless. Some combinations of card and power supply simply whine more than others, so a different power supply can change the sound, for better or worse.
5. Decide whether to return the card
If a new card whines loudly enough to bother you even with a frame cap, and it’s within the shop’s return period, returning or exchanging it is a reasonable option. Coil whine differs between individual cards, so a replacement may be much quieter. Under a normal warranty, makers often treat coil whine as normal behavior rather than a fault, so ask before sending it in.
Avoid “fixes” that involve opening the card and gluing or coating the coils. They can void the warranty and damage the card.
Real cases: what other users ran into
These are real reports from PC forums, summarized in our own words, with a link to each original thread.
Real caseASUS TUF RTX 4090SolvedA frame cap that almost silenced a new card
The owner heard loud coil whine under any load, audible over game sound even with the side panel on. Capping the frame rate at 240 FPS all but eliminated it. Another owner of the same card said a frame cap didn’t help much on theirs, and a forum moderator pointed out that coil whine also varies with the power supply.
Takeaway: a frame cap is the first thing to try, though results differ from card to card. See step 2.

Real caseCorsair RM1200x SHIFT · RTX 4070 SuperNot solved by the userThe whine was coming from the power supply
The owner heard an intermittent high-pitched whine, mostly at idle, that carried on even with the PC switched off but still plugged in. It continued with every part disconnected and with the power supply out of the case, which proved it was the power supply, not the graphics card. A replacement from the same brand whined too and was returned. The thread ends without a fix.
Takeaway: if you hear a whine with the PC off, look at the power supply first. See step 4.

Real caseMSI Gaming X Trio RTX 4090SolvedMuch quieter after an undervolt (and a risky extra step)
The owner opened the card and coated its coils with glue, then undervolted it. They said the whine was much better but not gone, and that with the undervolt the noise was “absolutely acceptable”. Other people in the thread found that a frame cap changed the whine but didn’t remove it, and one saw no change after swapping power supplies.
Takeaway: the undervolt is the safe part to copy. Opening and gluing a card risks the warranty and the card itself. See step 3.

Frequently asked questions
Is coil whine bad for my graphics card?
No. It’s a sound, not a sign of damage, and it doesn’t shorten the card’s life. It’s annoying, but it’s harmless.
Does coil whine go away over time?
Sometimes it softens a little, but you shouldn’t count on it. A frame cap or a lower power limit is a more reliable fix.
Why is coil whine loudest in game menus?
Many menus and loading screens have no frame limit, so the card renders hundreds or thousands of frames per second. That rapid power switching is exactly what makes coils whine.
Can a power supply cause coil whine?
Yes. The power supply has its own coils and can whine by itself, and some card and power supply combinations whine more than others. A whine at idle or with the PC off points to the power supply.
Is coil whine covered by warranty?
It depends on the maker and the shop. Many treat mild coil whine as normal. Within a shop’s return period, a return or exchange is often the easier route for a very loud card.
