Hi Toms,
This is a follow on from my previous thread (http://www.tomshardware.co.uk/answers/id-2345906/cpu-clock-speeds.html) that I said was solved before realising this was a problem.
I have just finished my new Build as follows:
i7-4790K
ASUS Z97-A
MSI GTX 970 Gaming 4G
16GB Kingston Hyper-X Beast (2133MHz)
Anyway, I thought I'd try overclocking up to around 4.5GHz seeing as the Turbo Clocks are already 4.3GHz but saw temperatures hitting the high 80s low 90s (according to HWMonitor) after just a minute or so of Prime95's "In-place large FFTs" test despite running with a Cooler Master Hyper 212 EVO in a Push/Pull config (I'm fairly sure my thermal paste is properly applied)
As such, I entered the BIOS and loaded the "Optimised Default" settings, turning off Q-Fan to help keep the system cool. Despite Intel SpeedStep being enabled, both CPU-Z and Task Manager show my CPU to be running at its Turbo Clock of 4.3GHz despite being at only 2-3% Utilisation.
Does anyone have any suggestions as to how to lower my temperatures to actually allow for an overclock amd how to fix this SpeedStep issue?
Thanks,
Conor

Update:
- I now know why SpeedStep wasn't working, I had Windows' "High Performance" enabled
- Still a little concerned about my temperatures
