Hi there, do not think it's an issue, but for a second or two my 5900x will boost up and then return to normal if I am just for example on a desktop with maybe a couple of web pages open. So just on idle then boost right up then back to idle, does not do it constantly just now and again. I think I have read its normal, but can't find a lot of info, just trying to learn, so any info is great. thanks
