I have a ryzen 2700x using a Scythe Fuma REV b cooler. I have tried disabling core performance boost to which I am greeted by 64c temperatures in a FPU,Cache, and CPU stress test in aida64. however when I enable core performance boost I get temperature spikes for a second(highest ive seen is an 88c temperature spike) which then cools down to 78-79c and then spikes back up again after a short bit is this normal? Idle temps are as low as 37c but spike as high as 54c
