CPU and GPU overheating in idle on newly-built Bitfenix Shinobi Core

Hello guys!

I just built my new rig, based on a Bitfenix Shinobi Core case. One 120mm front fan and one 120mm rear fan in the chassis.

I closed the sides and was looking forward to a fun round of GTA or Witcher with my new setup when I noticed that my system's overheating even in BIOS.

I played around with the fan speeds but apparently higher speeds don't change anything.

I decided to have another look at idle temperatures in Windows. My GTX 970 rose higher and higher to a steady 53°C while my 6700k stayed at 27°C which I would call desired. After I had a short look at MSI Afterburner and some forum entries, I looked back at the temperatures and saw that the 6700k catched up to roughly 55°C (see picture).

The 55°C area is also where they're both staying in idle. In Prime95 SmallFFT it doesn't get over 70°C, GPU stays at 58°C.

I have no idea what to do. 55°C idle is definitely not normal and the fans are really loud in that case, not what I imagined. I already changed the thermal paste on the CPU cooler (Noctua NH-U12S) and tried to switch the 2 chassis fans around a bit but not a single configuration made it look better. I don't think it's a badly ventilated case because turning up the fan speeds didn't better the situation either. But I'm still open for interpretation. Any ideas?

Setup:
Bitfenix Shinobi Core
i7 6700k
Noctua NH-U12S
MSI GTX 970 OC
ASUS Pro Gaming/Aura
2 BeQuiet 120mm PureWings 2 chassis fans
620W Seagate S12II Bronze PSU

Solution
Monitor all your voltages, If you can grab like a 10 dollar meter and measure the 12v rail, such as cpu connecter or gpu connector, mesaure positive yellow 12+ to grnd Black wire. It should read 12V +-5%

I don't have a meter in my possession.

You might be on the right track, though, because indeed the motherboard seemed to overvolt the CPU by default to 1.296V. I now reverted it manually to 1.2V as I read in another thread.

Speccy shows me 1.000V in the graphics tab.

You should check your airflow, does some components blow heat in another?
The trick is to get the air from the component direct out of the case.

You should defenetly check that, if not the problem: check your psu
