Just gave the google machine a bit of a workout and came up with this:I know for an absolute personally tested fact that it did on 775. Newer stuff I'm assuming it does.
I don't think it ever totally disables them (Power User used to, now I don't think it does), but it definitely changes where it bottoms out and/or where it prefers to sit.
Interesting question Archer....likely to be mobo/bios/cpu dependent, but on my IVY + GB ud5h mobo.....but on playing with settings on mine
If I disable C1e and C3/C6 and EIST in bios, SSD has full performance. When I go to power options, under CPU power management, I only have the option for cooling, ie presumably fan control. I do not have min/max processor state options, since my hardware setting of disabling c1e and c3/c6 and EIST makes them nonavailable, since hardware setting overrides any software control. Note, this causes an extra 20W usage while my computer is on vs turning on eist/c1e/c3/c6. I think once hardware disables eist/c1e/c3/c6, the only power savings are peripherals like IMOG suggested.
If I enable c1e, c3/c6 and EIST and overclock using dynamic, I then lose 40% of SSD 4k write and ~20% SSD 4k read performance. But, I then have access to min/max processor power states via software by going to power options, so I could "tune" min max processor states further.
This doesnt affect my ability to use sleep mode either way, as I overclock the easy way of turning off c1e, c3/c6, eist and just raise vcore/multi. My computer at idle uses 210W idling (280W including monitor). And sleep mode just 20W for everything, which goes into after 30 mins of not using computer. And of course 185-190W idle if I run same settings, but dynamic OC with C states enabled.
S4MBO, I've merged your thread into the main discussion about the TIM used on Ivy Bridge processors.
So it seems that we have come to a place where it is as it was. EZ overclocking is almost non existent.
Ok, so after using prime95 for 20 minutes, I got 58C on my hottest core, with H80 on "low". Stock everything, voltage was showing 1.120 on CPUz. Ambient was about 26C.
I think i'll check out the bios and start tweaking to see what I can get.
I can't recall a time previous to SB where 4.5GHz was a gimmie.
Both my IB chips do it (or more) easily with quiet cooling and acceptable temps.

What Ghz were you running your 3570k to get that on your H80?
I have a coolmaster V8 and was thinking of getting a H80 or H100 but not sure if it's worth the upgrade or not.
with sb dont you just need multi and a dab of vcore for 4.5? some lucky buggers didnt even need v core. oh yea and pll overide, mine wont even go past 4.4 without pll OR
