Overclocking my i7-4790k. Core Temp Results

[NinjaOfSEA]

So I recently built my PC. I have a i7 - 4790K CPU with a Noctua NH -D15 Tower Cooler on a Maximus VII formula motherboard. I am a complete newbie to over clocking and this is an initial attempt to overclock CPU. Im looking for two things:

1) Push my cpu to the absolute limit with my current setup. I understand liquid cooling allows for additional overclocking headroom but this being my first build was not too sure about a liquid loop.

2) Good overclocked setting for 24/7 running.

I have only changed the CPU voltage and the multiplier in the UEFI bios. After booting into windows, I run Prime 95 for 3 minutes to ensure stability before pushing the multiplier or voltage higher. I monitor the CPU temperatures in Celsius using Real Temp GT 3.7.0. Given below are my CPU clocks and temperatures: 

Multiplier x42 @ 1.150 V
Temps : 73 | 77 | 73 | 71

Multiplier x44 @ 1.150 V
Temps: 75 | 79 | 75 | 72

Multiplier x45 @ 1.150 V
Temps: 77 | 82 | 77 | 74

Multiplier x46 @ 1.150 V
Temps: Failed Prime95

Multiplier x46 @ 1.175 V
Temps: Failed Prime95

Multiplier x46 @ 1.20 V
Temps: 84 | 89 | 84 | 80

Multiplier x47 @ 1.20 V
Temps: Failed Prime95

Multiplier x47 @ 1.275 V
Temps: 100 C on CPU #2 - Stopped Testing

Final Result - Tested additionally with 15 Minutes of Prime95 - Stable Temperatures

Multiplier x46 @ 1.20 V
Temps: 86 | 91 | 86 | 82


What are my next steps?

Thanks in advance.

Those temps are awsome. Ignore people saying to lower the clock, that is apsolutley amazing!

thos temps are good mate, try doing some games and rendering and see the temps then you know the proper temps but they are good temps for prime95
