max cpu frequency on idle

[saltfish]

Since upgrading to windows 10 (clean install) my cpu (2600k) seems to spend a lot more time turboboosted to maximum frequency - when just web-browsing or idle.
I've looked in resource manager and it shows overall maximum frequency averaging around 48% to 80% but I can't find any single process thats using up a high % of cpu usage - The only thing is NT kernel using a lot of threads - but I guess that's normal? Is this just windows 10 being inefficient or have I overlooked something?

What does CPU-Z say? Ever since Windows 7 I never found Windows able to properly read the CPU speed for my 2600K.

cpu-z reads same as core-temp - frequency jumps up to max at least half the time on idle and web browsing
- but Ive just noticed something; it seems to calm down after about 40 minutes - what's going on ? Windows 7 didn't behave like this if I remember rightly

What are your power savings? On max performance mine is boosted at idle all the time, on balanced or power saver it reduces down to a 12x multi.

I'm on balanced power scheme - but I think I've found the culprit: mozilla firefox,anyone else getting this?

Not here.

Any plugins for Firefox that may be responsible?
