Hi. I have a question.
My case is Cooler Master Centurion 590.
I have 4790K stock box cooler and gpu Inno Ichill 980 ti OC 3x.
I have a weird single plastic creaking ( clicking ) noises coming from directly cpu cooler. Its only when pc is cooling down or heating up. Under load its dissapearing and its quiet.
Its very weird, because when i put load on Prime95 it doesnt click after or at start. Prime95 doesnt cause the noise.
Its always when i start to heating up my gpu by running a game. Or when quiting a game ( cooling down ). And yes i am sure its coming from cpu fan , not gpu.
My gpu have 3 fans , could be that hot air blowing from gpu to cpu making expanding CPU cooler and thats why it creaks ? Any suggestions?
 
Maybe one of the fan blades is catching on the heat sink when it reaches a certain speed??

It can happen if one of the blades is out of balance.

I think it is not out of balance. Because i stressed with Prime95 cpu and it doesnt tick \click. ( after or before ) Cpu is here stressed . Only i can heard single plastic clicking noises after ( cooling down ) or at starting games ( heating up ). Any suggestions?


If it was really of out balance then on prime95 it will start clicking\ticking, but it doesnt.

The thing between the CPU and the fan is the heatsink. So called because it is designed to absorb heat from the CPU, for the fan to then blow air over it to remove the heat. As such, when the CPU is under stress, the heatsink will heat up, and when the stress is removed, it will then cool down.

The heatsink is metal, and when metal heats or cools it expands or contracts, which produces noise.

Now, please - stop posting the same stuff in thread after thread, ignoring all the answers people provide and wasting everyone's time? Cheers.

Thank you for explanation. I am really patient now. :) Thx ;)

Confused Stu but explain me this. Why heatsink on cpu its not ticking before ( heating up ) and after ( cooling down ) using Prime95? ( 100% load )

Its only ticking after or at starting games. Can you explain me this?

Could be that ,hot air blowing from gpu to cpu making expanding CPU heatsink and thats why it ticks\pops?
