Creaking noises coming from cpu area when cooling down or heating up.

[sew333]

Intermittently, there will be a sound coming from cpu area that sounds like a single no regular ticking. This usually happens as the system is coming out of load or going into load.
Noise is coming from near cpu fan.
Whenever i run a game , and pc is heating up i can hear that single no regular ticks. And the same when i quitting game and pc is cooling down.
Its just when its cooling down or when heating up. But not under load.
What can it be?





my pc is:
case Cooler Master Centurion 590
Asus Sabertooth Z97 Mark 2
8gb ram
4790K ( stock box cooler )
Corsair 750 RM
Inno IChill 980 Ti ultra 3x
