Can CPU overheating cause permanent slowdown?

[shioriharu]

So i've experienced my second computer shutdown due to overheating in 2 years.
The first one was during a game called RIDE that caused my CPU to go 80C and shut down (even on lowest settings and on window mode)

I uninstalled that game and had no problem for a while, but it came back today as i was playing Dragon age Inquisition.
The game usually makes CPU temp go above 67C but always below 71C after several hours.

This time it went over 82 and computer shut down.

After waiting a bit to cool off and restarting, i noticed shadow flickering within the game that i havent before (it could have been always there though, cause im often just really paranoid),
and the overall performance seems to be a bit worse (stuttering, lagging) even on just webpages and also other games.

Funny enough now cpu temp is around 59 when playing for several hours, so i am curious, can CPU overheating cause permanent slowdown, even though HWmonitor and such says everything works just before the shutdown, or i'm just being too paranoid and my mind is deceiving me ?


By the way, its an AMD fx 8350 4ghz

Yes over the long term, you should've taken care of the cooling issue when you were crashing in RIDE.
Either replacing the Cooler or just making sure you installed the Heatsink properly.

What do you mean over the long term? Even if it is on normal temp for most of the time, it could be that it became permantently slower, even though monitoring softwares still say it's running at the same ghz ?

We are dealing with internal structures that are measured in Nanometers. When lets say the structure changes due to higher temps and voltages changing the structure. (There is a reason why overclockers do not push more than a certain voltage, but if they do they use Sub zero cooling.)

What can happen is the structure is so damaged that there are errors happening while running code in the CPU, this will lead to error correction built into the cpu halting the whole progress of the pipeline and starting over. So what you see as a slow down is actually your CPU probably doing alot of error correction.

A CPU should never be crashing under normal loads. A Game is a normal load.

Overclockers use Prime95 and other programs to stress their overclock to make sure they are 100% stable.
However 99% of the time you'll never stress the CPU as much as Prime95 can.

Okay, thanks for information. It turned out my CPU is a-ok.
There was something that made my temp jump at odd times and i'm thinking it was avast.
When just booted, and nothing ran at the background, but avast, my idle temp read was at 68C
Disabling avast put it back down to 43C in no time.

CPU slowdown feeling gone too.
