I have had my pc (i7 4790k gtx 970) for a couple of months now and recently i am noticing that my cpu has high idle temps (40-50). it was not like this before (more like low 30s). in cpuz it tells me that my cpu is running at 4.4 ghz (even though the voltage is still low). under load and in games, my usage and temperature are normal like they used to be 50s and 60s. after my cpu is at a high idle temp for a while it randomly drops back to low 30s and stays like that, with my clock speed staying lower. again, everything at load is fine but idle is worrying me. i have set power settings to balanced (5%-100%) and i dont know what to do. i am using hyper 212 evo, no overclock. Thanks!
