This happened all of a sudden. I wasn’t error - 6550 ora-06550 out of an overheated CPU while using it. It happened when I just turned on my PC in the morning like everyday for the past couple years. Except this time around I was greeted by the “CPU Fan Error, Press F1” screen.

sprers.eu(the cpu fan error press f1 bios managed to get into header content-type image/jpeg error BIOS screen by pressing F1 the first time, but panicked so I turned the PC off (noting that the CPU temperature was steadily rising to 68 Celsius in that minute or so I was in BIOS, it doesnt seem like it was stopping). Fans seem to be spinning, so is it the problem with the coolant I’m using?

Now I can’t even press F1 to continue after that first time. (keyboard works on another device). Still clueless on what’s happening even after googling around last night.

I’ve since opened it up and cleaned it all the best I can with compressed air, etc, and without messing with any cables. But the problem still remains. Forever stuck at that CPU Fan Error screen, pressing F1 (or any key) doesnt do anything :(

How to Fix a CPU Fan Error

The Central Processing Unit (CPU) fan error is a common error message that can appear when starting up a Windows desktop computer or laptop. The warning is usually triggered after a computer has shut itself down due to overheating. It may happen when the fan (or fans) cannot cool the hardware sufficiently.

While frustrating, the CPU error message and the forced shutdown indicate the computer's safeguards are working correctly. If the fans aren't working and the computer continues to overheat, it can permanently damage hardware components.

There are ways to confirm the cause of overheating and the resulting error messages, as well as ways to fix them.

How the CPU Fan Error Appears

The CPU fan error commonly appears during a Windows PC's bootup or start-up process; it does not appear during regular Windows operation. The error message text usually appears as one of the following:

  • "Error: CPU Fan Has Failed!"
  • "CPU Fan Error"

What Causes CPU Fan Errors?

A CPU fan error on start-up is typically due to physical damage to the fan, incorrect settings, or external factors causing the computer to overheat and force the fan to run at unusually high speeds. Dust or other objects obstructing the device's air vents can cause CPU fan errors.

How to Fix a CPU Fan Error

Because hardware and software problems can cause CPU fan errors, fixes are equally varied and involve checking specific settings and the internal CPU fan.

Follow these tips to avoid CPU overheating and error messages.

  1. Move your computer. Leaving your computer in an area with a lot of heat or sunlight can cause it to overheat and shut down, no matter how hard the fan is working. Try moving your computer to a cooler room and never place it in direct sunlight throughout the day.

  2. Stop overclocking. A consequence of overclocking is a dramatic increase in system heat that the default fans can't manage. Overheating can damage circuits and cause frequent shutdowns and overheating errors.

  3. Keep your computer cool. The easiest way to clean the air vents is to remove the brush from your vacuum cleaner, then use it at full power to suck any dust and debris out. Alternatively, use an airgun or canned air to blast the dust out, cpu fan error press f1 bios.

  4. Clean the CPU fans. For this step, cpu fan error press f1 bios, you'll need to turn your computer off, unplug it from the power source, and open up the case. Once opened, you can clean the interior and remove dust with an air gun or canned air.

    Refrain from spraying any cleaning agents onto any parts, as this can seriously damage various components.

    Many devices, such as the Microsoft Surface line of products, are not designed to be opened, and doing so may void the warranty or cause permanent damage. Reference your device's official support manual or call customer service if you're unsure.

  5. Check your CPU fan. While you have your computer opened, physically check your device's fans to make sure they haven't loosened or fallen out of place. Depending on your fan model, you should be able to fasten your fans back into place with a screwdriver or glue.

    Whenever you're checking anything in the interior of an electrical device, cpu fan error press f1 bios, make sure that it is completely turned off and disconnected from all power sources. Remember to choose Shut Down, not Sleep, when turning your computer off.

  6. Check your CPU fan's location. If you've installed the CPU fan yourself, ensure it's in the correct place, cpu fan error press f1 bios. You should have connected it to the CPU header on the motherboard, cpu fan error press f1 bios. If you've connected it elsewhere, the fan may run when the computer is on, but it won't sufficiently cool the CPU, which is its primary purpose.

    The CPU header will likely be labeled "CPU Fan," but if it isn't, it's still easy to spot with its three holes for the fan's three-pronged plug.

  7. Try an alternate CPU fan header. If you have multiple CPU fan headers on your motherboard, try plugging the fan into a different slot. Doing this sometimes fixes the CPU fan error.

  8. Check the CPU fan's settings in BIOS. You can use it to troubleshoot tech issues and make sure everything is as it should be.

    Open BIOS, then select Advanced Settings > Hardware Monitor > CPU Fan. Enable Active Heat Sink and Fan Duct with Fan and disable Passive Heat Sink and Fan Duct without Fan. Save your changes and exit BIOS.

    You'll often be prompted to press F1 when you get the initial CPU error message. Pressing F1 when this message is visible will also open BIOS.

  9. Change the BIOS setting. If you can see your CPU fan working correctly and you're sure your computer isn't overheating or running too hot, this change to the BIOS setting in step No. 8 can bypass the CPU fan error message and get your device up and running.

    To do this, open BIOS and select Monitor > Fan SpeedMonitor > N/A > Ignore > Exit > Save Changes.

    This setting can affect your computer's ability to detect CPU fans and cause overheating problems in the future. We only recommend it if you are sure that your CPU fan is working and you can test your laptop's temperature.

  10. Replace the CPU fan. If none of the above works, your fan could be broken and need replacing. Your computer's warranty may cover the repair of the fan. If you purchased the fan separately, it might have a separate warranty you can use to get a free or discounted replacement part.

This happened all of a sudden. I wasn’t booted out of an overheated CPU while using it. It happened when I just turned on my PC in the morning like everyday for the past couple years. Except this time around I was greeted by the “CPU Fan Error, Press F1” screen.

I managed to get into the BIOS screen by pressing F1 the first time, but panicked so I turned the PC off (noting that the CPU temperature was steadily rising to 68 Celsius in that minute or so I was in BIOS, it doesnt seem like it was stopping). Fans seem to be spinning, so is it the problem with the coolant I’m using?

Now I can’t even press F1 to continue after that first time. (keyboard works on another device). Still clueless on what’s happening even after googling around last night.

I’ve since opened it up and cleaned it all the best I can with compressed air, etc, and without messing with any cables. But the problem still remains. Forever stuck at that CPU Fan Error screen, pressing F1 (or any key) doesnt do anything :(

How the CPU Fan Error Appears

Usually, the ASUS fan error appears on bootup or during the startup process. The error message sometimes varies but you will see this text.

Fix ASUS CPU Fan Error on Boot
  • “Error: CPU fan has turned off!”
  • &#;CPU Fan error&#;

What Causes ASUS CPU Fan Errors on Startup?

This error shows that the motherboard safeguard feature is working fine. If the fans don&#;t spin properly then it may cause an increase in CPU temperature, resultantly it can damage internal hardware.

The most common reason that triggers this error is.

  • CPU fan isn&#;t connected with the motherboard cpu_fan header properly.
  • Incorrect fan settings in BIOS.
  • Dust and debris slowed down the fan RPM.
  • The fan is broken permenantly.

How to Fix CPU Fan Error on Boot/Startup

This error may be related to hardware or software so the fixes may differ for each user.

Users who are using Corsair or NZXT Kraken AIO CPU cooler mistakenly connect the wrong pump header in the motherboard. Hence see this error message.

Fix 1. Make Sure CPU fan is Connected Properly

This fan error is appearing on Asus & megatrends motherboard because either nothing is connected with the cpu_fan header or it&#;s plugged in the wrong header.

  • Please make sure the CPU FAN is installed on the right position of the motherboard and twist the screws tightly
  • For those who are using a water cooler i.e. Hi or Hi V2 and still fan speed error pops up, connect the hydero pump to the AIO_PUMP header (not in CHA_FAN).
  • Ensure that the CPU FAN cable is securely installed to the CPU_FAN connector instead of the CHA_FAN.

Fix 2. Set CPU Fan Speed Lower Limit

Does the CPU fan is running at a required RPM? Most of the time the Asus fan error gives you a hint that the fan is underperforming concerning its RPM.

For users who are using NZXT, Corsair fan with lower revolution speed, the system may not be able to correctly detect it.

Set the &#;CPU Fan Speed Low Limit&#; to RPM in BIOS configuration.

To change fan speed lower limit, follow these steps:

  1. Get into BIOS by pressing F1, F10 or Delete key upon startup.
  2. Navigate to the CPU fan settings with in Advanced Settings. (This section may vary with your motherboard&#;s model.
  3. Find the setting that controls the CPU fan RPM alerts. The default value should be RPM (Revolutions Per Minute).
  4. Lower the default to RPM to RPM and Save the changes.
  5. Exit the BIOS and boot the system.

Fix 3. Disable CPU Fan Speed Monitoring in ASUS BIOS

If the CPU fan error is appearing but a fan is working then you can disable this alarm. Follow these steps:

  1. Boot into BIOS.
  2. Navigate to the aforementioned Advanced settings.
  3. Look for the Monitoring (Monitor) section.
  4. Change the CPU Fan Speed to Ignore and Confirm changes.

Fix 4. Update BIOS

Most of the time fan errors on ASUS and Megatrends related to BIOS software malfunctioning. If you simply update the BIOS version to its latest then you are good to go.

Fix 5. Check fan Settings in BIOS

If you have recently changed the BIOS settings then it may be a cause why the Asus fan error is appearing.

  1. Open BIOS
  2. Select Advanced Settings.
  3. Select Hardware Monitor.
  4. There you will see the CPU Fan option.
  5. Enable Active Heat Sink and Fan Duct with Fan.
  6. Disable Passive Heat Sink and Fan Duct without Fan.
  7. Save your changes and exit BIOS.

Fix 6. Replace The CPU Fan

If the error is still appearing on the Asus motherboard on boot up, then it may be a hardware problem. You need to buy a CPU fan and replace it with a broken fan.

Fix 7. Clean the CPU Fan

The dust is the enemy of computer hardware. When dust builds up inside it blocks fins to rotate at ideal speed.

You should regularly clean the CPU fans. To do this turn of the PC unplug the power cable and use canned air to blow the dust off.

Modern motherboards have multiple fan headers if one header doesn&#;t work. Try plugging the fan into a different slot. This sometimes fixes the CPU fan error.

This happened all of a sudden. I wasn’t booted out of an overheated CPU while using it. It happened when I just turned on my PC in the morning like everyday for the past couple years. Except this time around I was greeted by the “CPU Fan Error, Press F1” screen.

How to Fix a CPU Fan Error

The Central Processing Unit (CPU) fan error is a common error message that can appear when starting up a Windows desktop computer or laptop. The warning is usually triggered after a computer has shut itself down due to overheating. It may happen when the fan (or fans) cannot cool the hardware sufficiently.

While frustrating, the CPU error message and the forced shutdown indicate the computer's safeguards are working correctly. If the fans aren't working and the computer continues to overheat, it can permanently damage hardware components.

There are ways to confirm the cause of overheating and the resulting error messages, as well as ways to fix them.

How the CPU Fan Error Appears

The CPU fan error commonly appears during a Windows PC's bootup or start-up process; it does not appear during regular Windows operation. The error message text usually appears as one of the following:

  • "Error: CPU Fan Has Failed!"
  • "CPU Fan Error"

What Causes CPU Fan Errors?

A CPU fan error on start-up is typically due to physical damage to the fan, incorrect settings, or external factors causing the computer to overheat and force the fan to run at unusually high speeds. Dust or other objects obstructing the device's air vents can cause CPU fan errors.

How to Fix a CPU Fan Error

Because hardware and software problems can cause CPU fan errors, fixes are equally varied and involve checking specific settings and the internal CPU fan.

Follow these tips to avoid CPU overheating and error messages.

  1. Move your computer. Leaving your computer in an area with a lot of heat or sunlight can cause it to overheat and shut down, no matter how hard the fan is working. Try moving your computer to a cooler room and never place it in direct sunlight throughout the day.

  2. Stop overclocking. A consequence of overclocking is a dramatic increase in system heat that the default fans can't manage. Overheating can damage circuits and cause frequent shutdowns and overheating errors.

  3. Keep your computer cool. The easiest way to clean the air vents is to remove the brush from your vacuum cleaner, then use it at full power to suck any dust and debris out. Alternatively, use an airgun or canned air to blast the dust out.

  4. Clean the CPU fans. For this step, you'll need to turn your computer off, unplug it from the power source, and open up the case. Once opened, you can clean the interior and remove dust with an air gun or canned air.

    Refrain from spraying any cleaning agents onto any parts, as this can seriously damage various components.

    Many devices, such as the Microsoft Surface line of products, are not designed to be opened, and doing so may void the warranty or cause permanent damage. Reference your device's official support manual or call customer service if you're unsure.

  5. Check your CPU fan. While you have your computer opened, physically check your device's fans to make sure they haven't loosened or fallen out of place. Depending on your fan model, you should be able to fasten your fans back into place with a screwdriver or glue.

    Whenever you're checking anything in the interior of an electrical device, make sure that it is completely turned off and disconnected from all power sources. Remember to choose Shut Down, not Sleep, when turning your computer off.

  6. Check your CPU fan's location. If you've installed the CPU fan yourself, ensure it's in the correct place. You should have connected it to the CPU header on the motherboard. If you've connected it elsewhere, the fan may run when the computer is on, but it won't sufficiently cool the CPU, which is its primary purpose.

    The CPU header will likely be labeled "CPU Fan," but if it isn't, it's still easy to spot with its three holes for the fan's three-pronged plug.

  7. Try an alternate CPU fan header. If you have multiple CPU fan headers on your motherboard, try plugging the fan into a different slot. Doing this sometimes fixes the CPU fan error.

  8. Check the CPU fan's settings in BIOS. You can use it to troubleshoot tech issues and make sure everything is as it should be.

    Open BIOS, then select Advanced Settings > Hardware Monitor > CPU Fan. Enable Active Heat Sink and Fan Duct with Fan and disable Passive Heat Sink and Fan Duct without Fan. Save your changes and exit BIOS.

    You'll often be prompted to press F1 when you get the initial CPU error message. Pressing F1 when this message is visible will also open BIOS.

  9. Change the BIOS setting. If you can see your CPU fan working correctly and you're sure your computer isn't overheating or running too hot, this change to the BIOS setting in step No. 8 can bypass the CPU fan error message and get your device up and running.

    To do this, open BIOS and select Monitor > Fan SpeedMonitor > N/A > Ignore > Exit > Save Changes.

    This setting can affect your computer's ability to detect CPU fans and cause overheating problems in the future. We only recommend it if you are sure that your CPU fan is working and you can test your laptop's temperature.

  10. Replace the CPU fan. If none of the above works, your fan could be broken and need replacing. Your computer's warranty may cover the repair of the fan. If you purchased the fan separately, it might have a separate warranty you can use to get a free or discounted replacement part.
