Unreasonable ACPI SpeedFan temperatures?

[moradm]

Hi everyone.
Today I suddenly opened speedfan to check my laptop's temperatures. My laptop has really been slow, harddisk is 100% most of the time, very slow and gets stuck, and occasionally turns off while playing low-spec games (like Call of Duty2) compared to my laptop's power.
To my surprise, I see that speedfan is reading malfunctioned info:
Temp1 is 429496448C, and Temp1 is ACPI.
I know this reading is wrong, but this probably indicates some sort of chip malfunction?

My specs are the following:
Intel Core i7-3630QM @ 2.40GHZ - 2.40 GHz
8.00 GB Ram, (at this point, 7.89 GB usable)
64bit Windows 8.1
AMD Readon HD 7600M Series, 2048MB memory size

Now I know it is not reasonable for a game like Call of Duty 2 to cause -that- much overheating and turn my laptop off. Something is truly wrong.
It has been very slow for months now, harddisk is 100% used most of the time, I turned off most services and did alot of fixes that I found online.
I also do have a Cooler Master fan under it.

Just figured that this ACPI wrong reading might help me find the source of the problem.

Any help would be appreciated

Speedfan is pretty poor software. I'd have thought your laptop would come with its own/. Or try HWInfo-Sensors

If you haven't opened your laptop and blown the dust out in the last year then its time to do it again. Its the most common cause of laptop overheating and poor performance - dust build up.

Try using Hwmonitor and let me know the temps.
