Check your power usage with and without C-state and speed-step enabled. The difference may not be noticeable, but it could add up over time. Running your PC for 15 hours daily is reasonable.

Can't confirm for the i5-6500, but my i3-6100 [email protected] uses roughly 40W more at full load than when idle. From that chart:
http://www.hardwarecanucks.com/forum/har...ew-12.html
it seems the non-OC 6100 uses an extra 29W at full load versus idle. That adds about 11W extra when running at 100%. At idle, that gap would likely be small—possibly enough to run a case fan.
For me, just my two Dell monitors already draw 200W, so I don’t worry much about the extra watts from speedstep.
Hope this is useful for you

Thank you for the question. I don't use either manual or adaptive vcore settings. My Skylake vcore remains stable at 1.15v, and changing it won't noticeably impact its lifespan compared to adaptive mode.
