Mainboard cant read CPU Temp?

[Skull_Zockt]

Hey guys,

 

so the thing is, every time I play Playerunknown's Battlegrounds after some time the performance goes down.

After long troubleshooting I found out in a stresstest that the CPU temps keep getting up higher and higher and it ends in a bluescreen (dont get that when gaming, just the stresstest).

 

Well, turn up the fan speed and thats it I thought, but when I went into the Bios and there to the fan settings I saw that my system temp was at 37°C, but my CPU temp was at 0°C. Also the pc doesnt get any loud so I think it is the Cooler not getting any louder. Is there a way to fix this?

 

Btw. I can see the Temps via CoreTemp which went from normal 40°C up to 90+ followed by a bluescreen.

 

To my specs:

- Intel Core i7-4790k @ 4.00 Ghz

- MSI Z97 Gaming 5 Mainboard

- Alpenföhn Brocken 2

 

if needed:

- 750W PSU

- MSI GTX 1070 Gaming X

- 16GB Corsair Ram @1600 Mhz

 

Thank you very much,
