As processors become more powerful, their heat output has also increased significantly. More and more gamers and creators are opting for liquid coolers to help keep their CPUs cool.
However, many beginners or upgraders often have one common question when choosing a liquid cooler: Do liquid coolers still leak?



In short, thanks to years of technological improvements, modern All-In-One (AIO) liquid coolers have greatly reduced the risk of leaks — but that doesn’t mean there’s zero risk. In rare cases, leaks can still occur.



Why Are Modern Liquid Coolers Less Prone to Leaks?



Advanced Manufacturing Techniques

The technology behind liquid coolers has matured considerably. The tubing, fittings, and radiator joints now use more durable composite materials that resist high temperatures and repeated bending.



Rigorous Factory Testing

To ensure product quality, most brands conduct pressure tests and leak tests before shipping, making sure the cooler leaves the factory without defects.



Improved Coolant Formulations

Modern coolants use non-conductive, corrosion-resistant special formulas, which help prevent evaporation and crystallization. This keeps internal pressure stable and minimizes the risk of leaks.







What Can Cause a Liquid Cooler to Leak?





Severe impacts during shipping that damage the cooler



Abnormal use, such as excessive pulling or bending of the tubing



Long-term use exceeding 8 years



How to Minimize the Risk of Leaks





Avoid bending the tubes excessively during installation



Keep the inside of your case dry and tidy



Choose a reputable brand (such as darkFlash)



Consider replacing your liquid cooler if it’s beyond its warranty period

Case fans play a critical role in keeping your PC running cool and stable. When they malfunction—whether it’s strange noises, erratic spinning, or not spinning at all—it can lead to overheating, performance drops, or even hardware failure.

In this guide, we’ll walk you through common case fan problems and how to fix them step by step, ensuring your system runs smoothly and quietly.

If the fan still doesn’t spin, the fan itself may be defective and should be replaced.

2. The Fan Is Noisy or Makes Strange Sounds

3. The Fan’s RGB Lighting Isn’t Working

Keep in mind that fans often spin slowly at low system temperatures—that’s completely normal for smart fan profiles.

If the fan still spins abnormally, the fan itself may be defective and should be replaced.

A malfunctioning case fan doesn’t just make noise—it can compromise your whole system’s cooling efficiency. Thankfully, most fan issues are easy to identify and fix with a little inspection and testing.

To prevent problems down the line, invest in quality fans, clean them regularly, and keep your wiring neat and secure.

PC case fans aren’t built to last forever.

 Over time, wear and tear from dust, heat, and mechanical stress will eventually take a toll. Even the best-quality fans have a lifespan, so if one stops working after years of use, it’s not unusual—it’s just time for a replacement.

Looking for reliable, high-performance case fans? Explore the full lineup of darkFlash fans—built for silent operation, vibrant RGB lighting, and long-lasting durability.





Case fans play a critical role in keeping your PC running cool and stable. When they malfunction—whether it’s strange noises, erratic spinning, or not spinning at all—it can lead to overheating, performance drops, or even hardware failure.



In this guide, we’ll walk you through common case fan problems and how to fix them step by step, ensuring your system runs smoothly and quietly.







Common Reasons for PC fans not spinning





Dust buildup: Over time, dust and debris can accumulate on fan blades and bearings, leading to reduced performance or complete failure.



Power issues: Loose cables, faulty connections, or inadequate power supply can prevent fans from operating properly.



Physical Interference: Inadequate cable management might cause the fan blades hitting the cables and lead to slow downs or immobilization.



Faulty motors: Fan motors can degrade with use, eventually failing to spin at all.



BIOS misconfiguration: Incorrect settings in the BIOS may disable the fan or restrict its speed.



Software issues: Malfunctions in fan control software can cause the fan to behave erratically or stop working.



Identifying and Resolving Fan Issues

1. The Fan Isn’t Spinning





⚠️ Common Causes:





Insufficient power due to daisy-chain wiring



Improper cable splicing or loose connections



Malfunctioning fan hub or controller



Fan blades hitting loose cables

👉 How to Fix:





Power down your PC and unplug it from the wall



Open your case and check the fan connections—ensure the fan cable is securely plugged into the correct motherboard header or fan hub.



Try connecting the 4-pin fan directly to another motherboard header to isolate the issue.



You can also test the fan individually by unplugging it from the hub or series connection and powering it separately.

If the fan still doesn’t spin, the fan itself may be defective and should be replaced.



2. The Fan Is Noisy or Makes Strange Sounds





⚠️ Common Causes:





Dust buildup in the bearings or blades



Fan blades hitting loose cables



Vibration-induced resonance between the fan and case

👉 How to Fix:





Turn off your PC and inspect the fan closely.



Clean the blades and bearings using compressed air, a soft brush or alcohol wipes to remove any dust.



Ensure no cables are interfering with the blades.



Check for any physical damage like bent blades or worn mounts.



Test the fan in another system or on an open bench to rule out case vibration as the cause.



If the fan still makes strange noises, the fan itself may be defective and should be replaced



3. The Fan’s RGB Lighting Isn’t Working





⚠️ Common Causes:





Outdated or missing RGB firmware/software



Inadequate power supply



Improper RGB header connection

👉 How to Fix:





Connect the fan’s RGB (3-pin or proprietary) cable to a different RGB header on your motherboard or controller.



Ensure your motherboard lighting software is installed and updated (e.g., ASUS Aura Sync, MSI Center, GIGABYTE RGB Fusion).



If the issue persists, consider using a powered RGB hub to supply sufficient power to the lighting.



As a last check, test the fan’s lighting functionality outside your current build to confirm if it’s a hardware issue.



4. The Fan Spins Too Slowly





⚠️ Common Causes:





Fan speed settings configured to low via BIOS or software



Fan blades hitting loose cables causing slow downs



Internal temperature not high enough to trigger higher fan speed

👉 How to Fix:





Check if the cable is interfering with the fan blades.



Boot into BIOS or open your motherboard’s fan control software.



Adjust the fan curve to increase speeds earlier or set a custom performance profile.

Keep in mind that fans often spin slowly at low system temperatures—that’s completely normal for smart fan profiles.

If the fan still spins abnormally, the fan itself may be defective and should be replaced.



Final Thoughts

A malfunctioning case fan doesn’t just make noise—it can compromise your whole system’s cooling efficiency. Thankfully, most fan issues are easy to identify and fix with a little inspection and testing.
