PC not outputing video

I am building a new pc with the following parts.
mobo-Z390 Pro4
GPU-GTX 1050ti
cpu-i7 9700F
16 Gb ram
psu-RM650X
corsair H100i elite capellix cpu cooler
The computer is turning on with lights but the cpu cooler fans are not spinning. I have breadboarded it and that did not work.

  • Ensure that the CPU cooler’s fan cable is plugged into the correct CPU fan header on the motherboard (usually labeled CPU_FAN). Confirm that the connector is fully seated and oriented correctly.
