Incorrect CPU Fan Speed and Temperatures

So, I'll go through this briefly:

One day, I had to move my computer from one place to another, ( this included a car drive ).
When I had installed the computer on the second place and booted it up, everyone went fine until these CPU Temperature errors started popping up, saying that my CPU was at like 65 - 75 degrees in idle, I ignored it and hopped into a game with my friends and after 10 - 15 minutes my computer shutdown, the cause of the shutdown was the CPU Temperature readings.

So, I've done alot of testing and have come to the conclusion that my CPU Sensors are invalid, both the temperature ones, and the CPU Fan Speed ones.

This is troublesome since my BIOS, sometimes doesnt let my computer to boot up since it doesnt think my CPU Fan is spinning ( when it actually is ), although, this is random, and sometimes it works. The same thing goes for the temperature, my idle temperature is everything from 30 degrees up to 60, and it's all random. Sometimes, It jumps from 30 degrees to 60, in an instance, and then back to something like 40.

My CPU is the AMD FX 8370 and the fan is the one that comes with it, I dont know the exact model.

Would getting a new CPU work, as I already have plans on doing that?
Or is there some other possible fix for this, help will be greatly appreciated.

Here's a picture of the graphs, showing the spiky temperatures:

And although I can't show any graphs for the fan speed, you'll have to take my word for that it constantly jumps from 1200 RPM to 0 RPM, within seconds, also seeming to be random.

Based on the fact you moved this PC and in a car ride... I am going to suggest that you first remove the heat sink fan, clean up it and the CPU and then apply new thermal paste and re-seat the heat sink. I am guessing that it came loose. Another area to check are all of the case fan connection and the CPU/heat sink connection. Make sure they're snug. If heat is your issue...at least obvious issue, start with cooling components.

I forgot to mention that I have already done that, I have both applied new thermal paste and re-mounted the heat sink, and I've mixed around with the fan connections, nothing have come to any success.

Can you monitor the CPU fan speed? Are you getting high RPMs out of it? Check your fan curves/configs and see that they are cranked up for that CPU. Possibly resetting the fan speed parameters can help. If you can leave the case open to observe the CPU fan, do so while you try out a game... pay attention to the temps and see if the fan slows or stops, etc.

Yeah, I've already monitored the CPU fan speed breifly.
For example, when my BIOS says that the fan speed is 0, the fan is spinning like its 1k.
When SpeedFan, HWINFO and Speccy says that its dropping to 0, its still spinning like its 1k.
As I stated in the paragraph, I have already come to the conclusion that the sensors are some-how faulty.

Faulty or not, if your PC is overheating and shutting down, the temps must be reading correctly. No? I'm not sure what else to suggest other than putting the PC back in the car and driving the entire route backwards in hopes that it reverses whatever happened ;p
