Acer aspire 5740G issue with 4 cores

[5740Gi5]

Hello everyone.

I have a 5740G with i5 580m, 8gb ram,240gb ssd and rx 570 egpu. Unlocked bios from this forum.

I recently got a i7 920xm and i7 720qm both 4 core 8 thread cpus.

The issue is with both of them i get a acpi read of 96.1c on hwinfo ocasionaly. While the CPUs are at 60c on all other sensors. I believe its some motherboard issue or bios setting. The chipset is compatible and they work fine until the acpi goes into those temps causing them to run below base. I7 920xm runs at 1.1ghz during that.

If anyone has any idea i would be very thankfull.

Regards
Mike
