Hello, this is my first AMD CPU and I'm a little unfamiliar with their behavior. I want to know if the zigzag temperatures I'm seeing are normal for a 2600X while idle. The difference in temperature is about 10C from low point to high point in the graph and the jump usually occurs in under a second. This happens even when the fan is set at max rpm (it just lowers the overall temperature but fluctuations still happen). My system consists of:
AMD Ryzen 5 2600x
ASUS ROG Strix X470-I
G-Skill Flare X DDR4 3200
I'm not worried much about the temperature level, it's just the constant fluctuations that bug me, my previous CPU's temperature would idle within a +/- 1C range. I've attached a Ryzen Master screenshot to show the weird behavior with fan at ~1800 rpm. I'm pretty sure this happens under load too just at a higher overall temperature, will try to get a second screenshot later today. In the meantime, is this normal or should the processor be RMA'd?
