Your graphics cardGPU (graphics card): The graphics card: the part that creates the picture you see on the monitor. More in our PC basics glossary →Close ✕’s fans aren’t spinning, and you’re worried it’s broken or about to overheat. Take a breath: most modern cards switch their cooling fans off on purpose when they’re cool, to stay silent. The fans only start once the card warms up. A quick temperature check tells you whether that’s what you’re seeing, or whether something really needs fixing.

Normal or a problem?

The temperature and the moment the fans stop tell you most of what you need to know:

Fans not spinning: normal or a problem?

Check the GPU temperature first. It tells you which side you're on.

Usually normal

• Fans stopped on the desktop, GPU below about 50–60°C
• Fans spin for a moment at power-on, then stop
• Cooling fans start a few minutes into a game
• The card has a "0dB", "Zero Frozr", "Freeze" or "Zero RPM" feature

Needs attention

• The fans don't start while gaming and the temperature keeps rising past about 80°C
• One fan spins and another never does, even under load
• Fans stopped after you moved, cleaned or repaired the card
• Grinding, clicking or a fan that feels stiff when turned by hand

Hot and silent? If the fans don't start and the GPU passes about 85°C, close the game and fix it before playing again.

1. Zero-RPM mode is doing its job

Most graphics cards from the last several years switch their cooling fans off completely when they’re cool, typically below about 50–60°C. A large metal heatsinkHeatsink: A block of metal fins that pulls heat away from a chip. Fans blow air through it. More in our Cooling & noise glossary →Close ✕ can keep the chip cool on its own while you browse or watch videos, so there’s no need to make noise. Card makers give the feature their own names: ASUS calls it 0dB, MSI calls it Zero Frozr, Zotac calls it Freeze, and AMD’s driver calls it Zero RPM.

It’s also normal for the fans to spin briefly when you switch the PC on and then stop. That’s the card’s normal startup test.

How to check: watch the GPU temperature in Task Manager, or in a free tool such as HWiNFO or GPU-Z, while you start a game. The fans should kick in somewhere around 50–60°C. If they do, everything is fine.

Not sure whether your temperatures are in a healthy range? Our guide on how hot a GPU should run has the numbers.

Prefer the fans always on? Most card maker apps let you switch zero-RPM mode off, or you can set a fan curveFan curve: A setting that decides how fast the fans spin at each temperature. More in our Cooling & noise glossary →Close ✕ with a slow, constant speed. It’s a matter of taste, not safety.

2. A fan curve or tuning app is overriding the card

Apps like MSI Afterburner, ASUS GPU Tweak, Gigabyte Control Center and AMD Adrenalin can all take control of the fans. A custom profile set to 0% at low temperatures, a curve that was saved by mistake, or two of these apps fighting each other can leave the fans stopped when they shouldn’t be.

Fix:

1. Open each fan control app you have and set every fan to Default or Auto.
2. Keep only one of them installed. Uninstall the others.
3. Restart the PC and test with a game while watching the temperature.

If you want a quieter custom curve that still protects the card, our guide to a loud graphics card fan shows how to set one safely.

3. A driver update broke fan control

A driver is the software that lets Windows talk to the graphics card, and fan control goes through it. Now and then a driver update causes trouble. In May 2026, for example, some Radeon owners reported that after installing Adrenalin 26.5.1, their cooling fans could stay at 0 RPM after the monitor went to sleep, even as the card warmed up.

Fix, in order:

1. Restart the PC. That alone fixed it for some of those Radeon owners.
2. Reinstall the driver cleanly. Display Driver Uninstaller (DDU), a free tool, removes every trace of the old driver first; then install the latest one from NVIDIA or AMD.
3. If the problem started right after an update, go back to the previous driver version.

4. A fan cable inside the card is loose

The fans on a graphics card plug into the card’s own circuit board through small cables hidden under the plastic cover. If a connector works loose, that fan stops, or the card can no longer read or control its speed. This is much more likely if the card was recently taken out of the PC, carried, cleaned or repaired.

How to check: if one fan stopped while the others spin, or all fans stopped just after the card was moved, suspect a loose cable.

Fix: if the card is under warranty, contact the maker before opening it, because removing the cover can void the warranty. If you’re comfortable and the warranty has ended, unplug the PC, take the card out, remove only the screws holding the fan cover (not the cooler), and press each fan connector firmly back into its socket.

5. A fan has failed

Cooling fans wear out, especially after several years of daily gaming. A failing fan, usually a worn fan bearingFan bearing: The part inside a fan that lets it spin smoothly. A worn bearing grinds or rattles. More in our Cooling & noise glossary →Close ✕, often gives warning signs before it stops: grinding, rattling or clicking, or a fan that only starts when you nudge it.

How to check: with the PC off and unplugged, turn each fan gently with a finger. A healthy fan spins freely and smoothly. A stiff, rough or wobbly fan, or one that stops much sooner than the others, is likely failing.

Fix: under warranty, start an RMARMA (warranty return): Sending a faulty part back to the shop or maker under warranty to be repaired or replaced. More in our PC basics glossary →Close ✕ (a warranty return). Out of warranty, replacement fan sets for many popular cards are sold online: see how to replace a GPU fan to find the right part and fit it. Until it’s fixed, avoid long gaming sessions. If you also hear noise from the other fans, our guide to a loud graphics card fan explains how to tell which one it is.

Dust can also make a fan struggle. If the card hasn’t been cleaned in a year or more, clean it before you decide a fan is dead.

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 caseRTX 3060Solution not confirmed by the userStopped fans on the desktop that were never a faultRead what happened

The owner noticed the fans didn’t turn at all while the PC sat on the desktop and wasn’t sure it was normal. Several replies said the same thing: many cards, including their own RTX 3060s, keep the fans off until the card reaches a set temperature, around 50°C, to stay quiet. The owner thanked them but didn’t say what they found afterwards.

Takeaway: check the temperature before you worry. Below about 50–60°C, stopped fans are expected. See cause 1.

Real caseZotac RTX 3070SolvedThe fans stopped when Windows loaded: a loose cableRead what happened

After a driver update, the fans spun during start-up but stopped as soon as the driver loaded, and the NVIDIA app showed 0 RPM. A clean driver reinstall and a rollback changed nothing. The owner remembered the card had been taken out a while earlier to swap a drive. On inspection, the cable connecting the fans to the card was loose. Once it was reseated, both cooling fans spun and reported their speed again.

Takeaway: if the card was moved recently, check its fan cable before blaming drivers. See cause 4.

Real caseASUS ROG Strix RTX 3080Not solved by the userOne fan stopped, another stuck at full speedRead what happened

After a gaming session, one fan had stopped completely while another ran near maximum, even with the card cool. Fan apps could only control the middle fan. The owner opened the card and found every fan cable firmly connected, and the problem stayed after reassembly. They suspected the card’s fan controller, but the thread has no replies or follow-up.

Takeaway: when the cables are fine and fans behave erratically, it’s likely a hardware fault for the maker to repair. See cause 5.

Frequently asked questions

Is it bad if my GPU fans don’t spin?

Not if the card is cool. Most modern cards stop their cooling fans below about 50–60°C to stay silent. It’s only a problem if the fans stay stopped while the card gets hot under load.

At what temperature do GPU fans start spinning?

It depends on the card, but usually somewhere around 50–60°C. Some cards also wait until the card is under load. Your card maker’s app often shows or lets you change the exact point.

Should I turn off zero-RPM mode?

You don’t need to. It doesn’t harm the card. Turning it off is worth it only if you find the fans starting and stopping annoying, or you simply prefer a constant quiet hum.

Why do my GPU fans spin at startup and then stop?

That’s normal. The card runs its cooling fans briefly as a check when it gets power, then hands control to its fan settings, which keep them off while it’s cool.

Can a graphics card work without its cooling fans?

Only while it’s barely working. On the desktop the heatsink alone is enough, which is why zero-RPM mode exists. In games the card needs its cooling fans, and without them it will slow itself down or shut off to protect itself.
