Core i7 965 Temperature Sensor is Dead?

Hello,

As weird as this might sound, my cpu is not reporting anymore the temp !!! it's as if the temperature sensor is dead...

i have a Core i7 965 installed on an Asus P6T6WS Revolution bios 407.

Cpu is liquid cooled and thermal paste used is Arctic Silver 5.

The system is working fine everything is working fine... It used to idel @ 28 degree celcius and peak to 65 if really stressed.

And then suddnely one night the temp was 45 degree and kinda was stuck there... i rebooted my pc entered the bios and the temp was still 45 and not moving at all.

I shutdown the pc and turned it back on and now the temp is "0" all the time. tired removing the power and rebooting again and it's the same. Wether i use the asus temp pc probe or sisoft sandra or check from the bios it's all the same. temp is "0".

If i put my hand on the water block it's running very cool even the water pipes and water itself it's all very cool.

Everything is working fine though...

Chipset temp is around 45.

Anyone any clue ? I couldn't find anything on google...
 
No, but why do you need to know what temperature your CPU is at?
 
Download this program and use it to monitor your temperatures: Real Temp

The programs you are using now read from a sensor built into your motherboard that is completely inaccurate, and in your case, appears to not be working altogether. Real Temp reads from sensors built into your CPU, which are much more useful. The values are still not perfectly accurate, but they are the best that you can possibly get.
 
I had this happen to me with a Xeon 3110. Just RMA'd it for a new one. I heard it was an issue with the earlier releases but I figured they would of had it fixed by the time Core i7 came out. Guess not!

Will try it tonight and see what happens...
 
To be fair, you don't need to stay at a certain CPU speed to avoid being arrested and you don't need to refuel your CPU either.

99.9% of people don't need to know or care what temperature their CPU is running at. Obviously that's not true for most people here but still, that's not a very good analogy. :p
 
Intel is great for RMA's with legitimate purpose... A chance to get a better overclocker too :)

Yea, but they're gauges so you know you're within a certain "safe" range... most people would not want to drive a car that didn't have a fuel-gauge or speedometer...

Same applies for someone with a $1000 processor... they want to know what temperature it's running at to keep it within a certain range, and know that their cooling is actually working...

Exactly... I don't have the temp monitor in front of me 24/7, but i have a liquid cooled system and a high end very expensive CPU, so i would like to be able to know @ what temp my CPU is running every now and then... it makes me feel better.

Kind of like driving a Ferrari to it's limits and not having a temp gauge on the dashboard... and then suddnely engine explodes...

You don't have to worry about keeping your CPU in a safe temperature range. Its thermal protection features will prevent any harm from coming to it. Temperature-monitoring programs are more for fun than any practical purpose.
 
Stay on topic and no thread crapping.


OP, as mentioned if you still get "0" with realtemp I believe Intel would have no issues with replacing that CPU.

Real Temp works...

Also after removing the power cord for several hours the temp came back in the bios... once i logged back into windows it froze again and same issue...

But Realtemp is working fine... seems i have some bios/driver/windows 7 incompatibility issue...

Well yea, your car isn't going to explode if you go over the speed-limit, a cop might pull you over... and nothing will happen when your car runs out of gas, except it will stop running...These are things you want to avoid though... just like having the thermal protection kicking in and shutting the computer down...

It's not that hard to understand why something like this would be necessary

Hope it works out for you rph, and that you don't have to deal with an rma...

Thermal protection won't shut the computer down outside of very extreme conditions. It'll just reduce the speed it runs at. And under normal conditions, the CPU won't even get near Tjmax, so monitoring it would be unnecessary.

I'm not saying that you shouldn't monitor your temps. However, there's really no practical reason to do so. Anyway, enough off-topic posting.
 
if u buy a dell sure its not practical, but practicality is different for everyone and in this case finding the temp of a $700 processor is very practical.
 
Yea who knows it's likely more a issues with your mobo than your cpu....
If you get a chance check it on a different comp.

And even than it may be driver isuses
