CPU fan on the heatsink is not spinning.

I just purchased the kit and put it together. The back-case fans are spinning without issue, but the CPU fan is not working at all. I tried to unseat it and reseat it with no change. I set the CPU to stress to 60 degrees, and you can see the RPM is at 0.

Please contact service@sunfounder.com to provide your order details and address to get a PWM fan.
