CPU Core Temp sensor damaged?

[Paxan_1]

Hi,

i have a little question about the temperature sensors of the cores in a cpu. I think the sensor of my core 1 & 2 are damaged. They always show 70°C in idle and 75°C in load. Core 3 & 4 is okay, 45°C in idle and around 60°C in load. The CPU sensor on the mainboard has 30°C.

 

The Cooler is okay, i've checked it out 2 times. To control the temperature i have placed one of the internal sensor cables direct on the heat-spreader. This one has 49°C.

 

Btw, the CPU is an Q9450 overclocked to 3.4 GHz.

 

Maybe someone of you have seen such a behaviour before?

More likely the sensor is just inaccurate or being misread by software - 49* C isn't a bad temperature, generally speaking (assuming that doesn't mean some huge delta from ambient) - what application or software are you getting these values from?

I had the idea with the misreading software, too. But after a clean install of my new Windows 7 it was the same like with Windows XP. The temperatures are the same in each program which can read and display them. I used Everest, CoreTemp and the Asus Software.

Well, my last computer had an automated system that sped up and slowed down its fan speeds according to how hot or cold the machine was running. One day it went psycho and randomly jumped to the highest possible setting, which actualy set my hair waving, anf then shut them off entirely, along with every other computer function, proclaiming proudly: "windows has shut off your computer to prevent a serious error!" I then tried to restart it and it simply wouldnt budge.

 

I'd recomend if you can afford it to have someone look at it but-but Im no expert on pcs and if one of the fiddly bits breaks I simply ship it to my good friends at the local pc repair shop. I break many a computer part, so they know my face and give me a 5% dscount when I've really buggered something up bad.

 

But also, what sort of climate is this in? until very recently I lived in semi-jungle in australia, that would be about uhhm.... 90-110 farenheit in every day in summer and a slightly more merciful 60-100 at night-both with high humidity, so it did drive two of my pc's mental with "computer-heatstroke"

I'm using a manual fan controller for that. I don't think it is a "real" problem, because if the sensor i patched to the heatspreader is around the temperature of the "cold" cores the cpu is okay. It is working fine and i haven't had any problems. Just thought i ask here if someone had seen such a strange failure.
