CPU @ 170C and shutting down...!

A sunnier or damper area than Ron-ski....
Hi folks,

Odd one - old CPU (Q6600) was running hot and shutting down a few months back, so yanked out the case and cleaned off and reapplied thermal paste. This seemed to radically reduce CPU temps back to normal ranges (ie 40-60C), however have noticed the same symptom has crept back recently and it's now shutting off when putting it under load (ie intensive CP activities like games, rendering etc).

I can do the same again, just seems strange behaviour and can't see why it's only lasting a few months - is there anything else that could be causing this?

HWMonitor reports the CPU Fan as running fine (2500rpm+), temp is 85C idle for CPU, Sys temp is 35C, SSD is 29C, GPU (GTX 970) is 40C - so feels system is reasonable....

Any ideas welcome before I yank out and silver paste again....!
 
It definitely isn't at 170C lol. It would shut off at around 100C and I imagine by 170C things would have started melting. :p

And as above 85C isnt OK either... 85 under full load is just about passable, but still not ideal.
 
Heh, you get my sense of something peculiar...!

Answering a few questions - no dafties things, eg leaving plastic etc - as per OP this has been in situ for about 7-8 years now and running much more sane temps.

And yes it is Celsius (350ish in Forum).

I'm not certain but I think 170C is the thermal hard shut off point for CPUs - don't think they'd shut at 100C etc unless something else triggering. Note this is correct temps so whilst 85C is clearly not normal, don't think any danger of damage at this point. 170c of course is different...!

Agree it could be a faulty temp setting - although odd it'd just start suddenly and certainly triggering the shut off regardless so problem remains.

Only other thing i can think is if the heatsink has become loose or isn't sitting tightly, might try swapping it out with another to remove that variable...

It just isn't getting to 170 degrees. It just isn't. It must be a faulty temperature sensor. Whether something else is at play or not is the matter to be debated.

170 degrees is pop, bang, smoke, fire, dead CPU territory. Not "oh dear" territory.
 
well it will say what temp its at in the bios or any other program. if i open core temp on skylake its says my cpu is at 100c at idle, load and never goes above or below it........... the software is just wrong lol.
 
You must mean fahrenheit?
170f - 76.7c
and
85f - 29.4c.

Edit
Just read that you confirmed it's Celsius. Ignore then.

Try the CPU in another motherboard.

This. Sounds like the motherboard is reporting temps incorrectly. Although finding a compatible motherboard could be a bit tricky at this point...I'd be tempted to just replace the whole rig with a low end Kaby build, sounds like its coming to the end of its days!
