Funny CPU Temperatures

[Cruncher]

Hi, I have a Asus Maximus V Extreme & 3770k@4.8Ghz~ And that computer works amazing good ! 🙂
But now I build 2 other systems, a Gigabyte G1 Sniper M3 & 3770K@4.5Ghz~ Also running perfekt
BUT the third system there is something wrong with 😞
Gigabyte Z97X Soc Force & 4790K.... the cpu temperature in the bios in jumping between 91° & 34° !!! every 2 seconds !!??
The waterblock (corsair H75) is perfekt attached on the CPU and I know, from Idle till Stressed teh temp can rise from 34° till 70°
But jumping every second between 91° & 34° is something I never been seen before 😞
Someone an idee how to solved this ??

Only look in the bios and used a widget to watch the cpu temp, tomorrow I go back to the shop, they gonna run a small diagnose test to see, they think there's something wrong with the 4790K because 70° is nermally the limit

Wonder what caused that crazy spike in temps, must be a broken or faulty sensor.
