when logging to a csv file with aida64, there are for a brief moments some very low drops in +12v (also on +5v, +3.3v and cpu core), and at the same moment a drop on the reading CPU fan and also all other fans ( CAHSSIS #1, #2 and #3)
 
	Motherboard: Gigabyte ax370-gaming-k7
 
	could it be a faulty PSU, Motherboard, or some bug in the bios ?
 
	regards,
