A small amount of pump noise during startup is normal. If the noise continues, check that the pump is connected correctly, running at the recommended speed, and that the radiator is installed properly. Air trapped inside the loop may also cause temporary noise.
The temperature shown on the digital display may differ slightly from third-party monitoring software due to different sensor sources, polling intervals, and calculation methods. Small differences are normal and do not indicate a product issue.
Check that no cables are touching the fan blades and that the fan is securely mounted. Dust buildup or debris may also cause abnormal noise. If the issue persists after cleaning and inspection, please contact CPS PcCooler support for further assistance.
Verify that your cooler supports CPS PcCooler software and that all required USB and power cables are connected correctly. Make sure you are using the latest version of the software and restart your PC after installation. If the device is still not detected, reinstall the software or contact technical support.
First, confirm that your cooler model supports software control. Then check all USB, power, and communication cable connections. Restart both the software and your computer. If the issue remains, reinstall the software or contact CPS PcCooler support for assistance.
If your PC does not start after installing a new PSU, check the following:
• Make sure the PSU power switch is turned on
• Confirm the AC power cable is properly connected
• Check that the 24-pin motherboard cable is fully inserted
• Check that the CPU 8-pin power cable is connected
• Verify GPU power cables are properly installed
• Ensure all modular cables are connected correctly
If the issue continues, test the PSU with another system or contact technical support.

Many modern PSUs feature zero RPM fan mode. When the PSU load and temperature are low, the fan automatically stops to reduce noise and improve lifespan. The fan will start spinning again when the PSU reaches a higher temperature or power load. This is a normal feature on many modern power supplies and does not indicate a malfunction.
