recently i bought a new cpu with coolermaster k380 chassis

however i followed the instruction, the side fan should be winding in to the gpu and cpu

before that i was set it up to wind out, that's totally fine, very quiet...

but not after i turn it over to wind in... very noisy...what to do?

OH ya, the fan im using is the coolermaster led quiet fan

you should have 1 fan to suck air in, and 1 fan to suck the hot air out

yea...i setup my fan like the chassis recommendation...
side fan suck the air in, and rear fan suck the air out...
but still very noisy...maybe the design of the space...

maybe there is much restriction... try reduce the fan speed...

Please check where the noise is coming from. The fan itself? Airflow noise? Casing rattling? CM fan is known as noisy fan...and the casing itself is tend to rattling due to thin Acrylic panel...

it's airflow noise.... ==

I think it's too near to GPU then the airflow is bit restricted or counter the GPU fan airflow. Try reduce the fan speed..
Side panel fan placement is only marketing gimmick.. For me enough with front & bottom intake...
