If you’re experiencing issues with your Deepcool LS720 liquid cooler, particularly with the pump not functioning, you’re not alone. Many users encounter this problem, but most can resolve it with some straightforward troubleshooting steps. This guide will walk you through common fixes to get your cooling system back to optimal performance.
Understanding the Deepcool LS720 Pump
The pump is a critical component of the LS720 liquid cooling system. It circulates coolant through the radiator and CPU block, ensuring efficient heat dissipation. If the pump fails or stops working, your CPU can overheat, leading to thermal throttling or shutdowns.
Common Causes of Pump Failure
- Power connection issues
- Electrical faults or damaged cables
- Blocked or air-locked pump
- Faulty pump hardware
- Software or BIOS settings
Basic Troubleshooting Steps
Check Power Connections
Ensure that the pump’s power cable is securely connected to the appropriate header on your motherboard or power supply. Look for any loose or disconnected cables and reconnect them firmly.
Verify BIOS Settings
Access your BIOS and check if the pump header is set to the correct mode. Some motherboards allow you to monitor pump RPMs or adjust fan/pump profiles. Enable any relevant settings to ensure the pump receives power.
Inspect for Blockages or Air Locks
Air bubbles or blockages can cause the pump to stop or run inefficiently. Carefully tilt or gently shake the PC to dislodge air bubbles. Also, ensure the radiator and tubing are free of obstructions.
Advanced Troubleshooting
Test the Pump Separately
If possible, disconnect the pump from the CPU block and connect it directly to a power source or motherboard header. If the pump runs, the issue may lie elsewhere in the system.
Replace or Repair the Pump
If the pump does not run during testing, it may be faulty. Contact Deepcool support or consider replacing the pump unit if under warranty.
Preventative Maintenance Tips
- Regularly check for leaks or damage
- Keep the radiator and fans clean from dust
- Ensure proper airflow inside the case
- Update motherboard BIOS and software
Proper maintenance can extend the lifespan of your cooling system and prevent pump failures. Always follow manufacturer guidelines for installation and upkeep.
Conclusion
If your Deepcool LS720 pump isn’t working, start with basic checks like power connections and BIOS settings. For persistent issues, testing the pump directly or contacting support may be necessary. Regular maintenance can help avoid future problems and keep your system running smoothly.
