Seasonic 1300w prime gold fan spinning at idle

[Vigorito]

Purchased a Seasonic PRIME 1300W gold PSU recently for my system (Ryzen 9 5900, msi tomahawk x570 ,rtx 3080 suprim x), intending to take advantage of the hybrid mode for silence at idle/low load. However, when the PSU is placed in hybrid mode the fan spins up every 10minutes or so for about 5-7 minutes when the system is idling creating a rather disruptive experience, given the rest of the system is effectively silent,case is lian li 011 dynamic,what i have notice that in the box was only 1x8pin cable (8 wires) and 6x 6+2 pcie cables with 6 wires,my last gx 1000w from seasonic has pcie 3x8pin 8 wires,i used that 2 pcie 6+2 cables (6 wires+1x8pin cable 8 wires for the gpu,could that cause the fan spinning in idle because of some issue with the power on pcis slots

-My hear is perfect still
-All in task manager is very low
-I have found a lot of people are complaining on prime units for the same issue (for high wattage models)
-position of fan in case is good
-there is a lot airflow

1300w gold prime has now up to 20% hybrid mode not 40% like before,seasonic hybrid mode is decreased almost on all new models,but still 20% of 1300w i 260W in idle is crazy so thats not the problem or its faulty fan controler or fan curve is changed a lot

Didnt want do deal with a unit as i have found a lot of people are complaining for a fan noise in idle,but it doesent matter anymore,i allready sold that 1300w prime and switch back to regular gx1000 gold which doesent have issue while in idle.
