Note: Please do not remove the black block, it protects the CPU and raises the contact surface.

Step 3, Install new radiator

  • Align the heat sink fins of the new heatsink with the front panel of the ZimaCube, making sure the fan is placed facing the back panel .
    tips:The new radiator has been pre-coated with silicone grease, no additional application is required.

  • Then enter the intelligent fan control settings interface in ZimaCube BIOS. To optimize fan performance and ensure effective cooling of the system, it is recommended that you use the following recommended parameters:

    • Fan start temperature limit: 40°C

    • Fan full speed temperature limit: 90°C

    • Fan start PWM: 50

    • PWM Slope Setting: 0.5 PWM

*Tips: ZimaCube set to 1 PWM , ZimaCube Pro set to 0.5 PWM.

These parameters can help balance the noise and heat dissipation of the fan, ensuring that the ZimaCube can maintain stable operation under different loads.

  • After completing the settings, press the F10 key to save and exit.

Congratulations! You have successfully replaced the ZimaCube fan and optimized the BIOS settings. This ensures that the device remains stable and extends the hardware life under high load. If you have any questions or need further assistance, please feel free to contact our technical support team. Thank you for your patience!

This guide mentions how “the new radiator has been pre-coated with silicone grease”.
I am not familiar with silicon grease, what exactly is the function?
And does it replace thermal paste between the cpu and radiator? Or do I still need to apply some fresh thermal paste myself or leave the old paste on?
