I have an asus z170-a mobo, i7 6700k which I haven't overclocked but keeps jumping up between 4 GHz and somehow hitting 4.3 GHz even though it isn't overclocked. It also is running hot, idling at around 35 degrees with a cryorig h7 with a qf120 performance plus the default fan on the cooler. My ram is g.skill ripjaws V 16gb ddr4 3200, and case is corsair carbide series 100r. I have the stock fan from the case, the two on the cooler, and a 140mm cryorig one on front of the case. Speedstep is on and all c states are on in BIOS. I have already reset bios settings twice and this isn't fixing the problem, as well as making sure the processor isn't overclocked.
Edit: I also occasionally have one of my four cores go down to 800 MHz for a second or two. It's always core 0 or core 1 though
