CPU fan spins for about 10secs then stops repeats indefinitely

Spec
Asus z97m plus board
i74790k
Gskill 1333 4gb
Power supply cooler master G650m *

* Power supply brand new. Bought it thinking that was the problem.

Board and CPU less than 3months old.

Any help is appreciated.
Thank you.

Sounds like a short is causing the Power Supply to crowbar.  Disconnect everything but the motherboard, fan and power supply, pull out the RAM.  Any change?

Did that no change in behavior.

What are the chances it's the processor that's faulty?

Thanks for helping.

Did you try pulling the CMOS battery?    Hard to say what is wrong. I had an HP once where the problem was in the on/off switch assembly.   Does the fan in the power supply also turn off?  I assume the power supply is set to your local voltage?

Took it to a repair center. They concluded motherboard was faulty. Thx for taking time to reply.
