i7 5930k CPU throttling, power and voltage issues

Hi there,

I'm new to the forum and I have just built my first PC.

I wanted to overclock my i7 5930k to 4.0 GHz from its stock 3.50 GHz.

However prior to doing so I thought that I should do some initial testing of my hardware to see if there are any errors I could possibly run into.

I used Aida64, Corsair Link, CPU-Z, and Open Hardware Monitor to see where I was at in terms of CPU temp, Voltage and Power consumption, and to my surprise I did run into some numbers which do not make sense to me.

First of all my idle temps were hanging around 50-58C (annotated with red boxes), which I believe is pretty hot when not under load. Then when checking my voltages I compared CPUZ to Aida64's CPUID and my voltages read 0.945 V for CPUZ and 0.072V on Aida64's CPUID (annotated in purple) which does not make sense to me at all. And finally I went browsed over Powers in Open Hardware Monitor I saw that CPU cores was reading 0.0W (annotated in blue), which also does not make any sense to me at all. I saw pictures of other people using Open Hardware Monitor, and there is some small reading there.

What also surprised me was that not even 2 mins into stress testing, my CPU starts to throttle, even with a Corsair H100i GTX as my cpu cooler.

Could anyone please explain to me why this is happening?

My first assumption is that there isn't proper physical contact with the copper plate and the CPU or that the stock thermal paste provide isn't performing like it should be. (I haven't removed it yet to check, since I don't have extra thermal paste on me, but I am planning to buy some soon).

Second assumption is that maybe the monitoring software somehow did not install properly, therefore giving me bad numbers.

Or worst I some how screwed up when installing my CPU causing these errors to occur. (I really hope that this is not the case).

Your help is much appreciated.

I was able to confirm what was causing the CPU to overheat.

It was just really poor contact between the CPU block and CPU. Now I can safely do some overclocking :).

Thanks for all the help
