6 Reasons Why Your CPU Cooler Is Not Lighting Up
Before understanding how to fix CPU cooler not lighting up issue, let us first look at possible causes behind it. Here I am going to share some reasons why your CPU cooler is not lighting up.
1. Incorrect Addressable RGB Header Connection:
If your ARGB fans or strips are not lighting up, then check if you have connected them in the correct orientation. The 12V header usually has a + and – sign on it to show which way the connector should be facing. Make sure that you connect the ARGB header in the right way and the correct header as well. You can also refer to your motherboard manual for the correct header orientation.
2. Incompatible Components:
Another reason why your CPU cooler RGB might not be working is because of incompatible components. For example, if you are using an old motherboard with a new RGB CPU cooler, then there are high chances that the RGB headers will not be compatible, and the CPU cooler RGB will not work. It is always recommended to use compatible components from the same brand to avoid any kind of compatibility issues.
3. Bad Connection:
If you have double-checked and made sure that all the connections are correct, but your CPU cooler RGB still isn’t working, then it might be because of a bad connection. Check if the connectors are properly inserted in their respective headers and if there are any loose wires. You can also try reconnecting the ARGB header to see if that fixes the issue.
4. Defective or Damaged Components:
In some rare cases, the reason why your CPU cooler RGB is not working can be because of defective or damaged components. If you have recently dropped your CPU cooler or if it has been subjected to some kind of physical stress, then it is possible that the RGB LEDs might have gotten damaged. In such cases, you will need to replace the damaged component in order to get the RGB lighting working again.
5. Software Issues:
If you are using addressable RGB components from different brands, then there are high chances that you will face software compatibility issues. In such cases, you will need to use third-party software like Asus Aura Sync or Corsair iCUE to control the lighting of your addressable RGB components.
6. Firmware Issues:
In some rare cases, the reason why your CPU cooler RGB is not working can be because of firmware issues. If you are using an older motherboard, then it is possible that the RGB headers might not be compatible with the latest firmware version of your CPU cooler. In such cases, you will need to update the firmware of your motherboard or CPU cooler in order to get the RGB lighting working again.
Now that we know the underlying causes of CPU cooler not lighting up, let us read further to know about how to fix CPU cooler not lighting up.
How To Fix CPU Cooler Not Lighting Up – 11 Fixes
If you are facing problems with the lighting of the CPU cooler, then you need to fix the issue immediately. You can’t afford to deal with any issues because it will damage the performance of your computer. Let’s learn in detail about how to fix CPU cooler not lighting up.
The most common reason behind this issue is that the CPU cooler is damaged. If you have found that your CPU cooler is not lighting up, then you need to replace it immediately. If you don’t replace it, then the chances of the system overheating and causing damage are very high.
Here are some tips on how to fix CPU cooler not lighting up:
1. Check your power supply is switched on and working.
If it’s not, that could be causing the problem with your CPU cooler fan. To check this, press the switch at the back of your computer or on the front panel to see if there’s a light coming on. Also, make sure that any necessary cables are connected from the motherboard to the power supply unit (PSU).
If you can turn it on after all that, then you need to think about upgrading your PSU – either a new one for maximum performance and overclocking cooling fans or maybe just a more powerful PSU for those high-end graphics cards and CPUs taking up so much juice?
2. Check whether the CPU cooler fan is plugged in and connected to the motherboard.
If the lights are working on your power supply unit (PSU), then it’s time to check that the CPU cooler fan is plugged in and connected to the motherboard. This can be a simple matter of plugging it in or if you have some extra fans on your computer, maybe a little more difficult to find where each one should go. If you’re unsure, just look in your motherboard manual for instructions – there will be a diagram showing where each of the ports goes and how many pins they need – this depends on your motherboard.
3. Make sure that all sockets are as they should be.
Next, make sure that all sockets are as they should be: not loose and/or securely fastened with no bent pins which could cause either a problem starting up or prevent cooling fans from working altogether. Also, check that there is nothing blocking the airflow to your CPU cooler or any other fans in the case – sometimes people put extra hard drives or SSDs in and completely block off vents which will cause hardware to overheat and break.
4. Clean out all the dust from inside your computer case
Another thing you need to do is clean out all the dust from inside your computer case as this can build up over time and prevent air from flowing around properly, making your components work harder (and get hotter).
You can use a compressed air can (the ones for cleaning keyboards work great) or a vacuum cleaner with the hose attachment – just be careful not to touch anything sensitive with the end of the hose as it could easily damage it. If you have a desktop computer, it’s also a good idea to clean the dust out of the back of the CPU cooler fan as this can get blocked up and stop the fan from spinning properly.
5. Check your case fans
Once you have everything dusted out, check that all your case fans are working correctly. If not, then you may need to replace them. This is usually a pretty straightforward process and just involves unscrewing the old fan and screwing in a new one – although you will need to make sure that you buy the right size and type of fan for your particular computer case.
6. Add some extra case fans
Another quick and easy way to improve airflow (and thus help keep things cooler) is by adding some extra case fans. These can be bought cheaply online or in most computer stores and just need to be screwed into place. Just make sure that you don’t put too much in as this can create too much noise and actually make things hotter by not allowing enough airflow around all the components.
7. Check the BIOS version
Make sure that you have the latest BIOS version installed on your motherboard. This is important as each new revision usually comes with improved cooling solutions and fan control options. You can check what version you have currently installed by looking in the BIOS menu (usually accessed by pressing F2, DEL, or ESC during bootup) or checking the manufacturer’s website for your particular model of the motherboard.
8. Enable any CPU fan control options
Enable any CPU fan control options in the BIOS menu as this will allow you to better control the speed of the fans and thus make things quieter or cooler depending on your needs.
9. Check the fan
If you have a dedicated graphics card, then you should also check that the fan on this is working correctly as these can also get blocked up with dust over time. You can usually access the fan control menu by right-clicking on the desktop and going into the “NVIDIA Control Panel” or “ATI Catalyst Control Center” (depending on which brand of card you have). From here, you should be able to change the fan speed manually or set it to automatically adjust based on temperature.
10. Overclock your CPU and graphics card
One final thing you can do (although this may void your warranty) is to overclock your CPU and graphics card. This will make them work harder, thus producing more heat, but it should also allow you to achieve higher frame rates when playing games. Just be aware that overclocking is a very technical process and can easily damage your hardware if done incorrectly so only do this if you are 100% confident in what you are doing – otherwise just leave it alone!
11. Buy a new CPU cooler
Finally, if all else fails, then the last option (and usually the most expensive) would be to buy yourself a new CPU cooler and/or graphics card fan. Modern PC components are generally designed very well and shouldn’t need replacing unless they get damaged or blocked up with dust but sometimes even the best of them start to overheat after many years of use. If this happens, then you may need to invest in some aftermarket cooling solutions.
These were some of the effective ways on how to fix CPU cooler not lighting up issue. Follow the steps above to resolve the issue.
