Safe GPU temperature

[Murilo_A]

I have a problem with my PNY GTX 760 2GB, for some reason, it’s running hotter than normal, with MSI Afterburner locking at 80°C, core clock stays at 980MHz (default core clock), when I set it to 95°C (afterburner’s limit) it goes up to 95°C~97°C and 1124MHz (max GPU boost clock).

 

The thing is, is it safe to run at this temperature? According to PNY website, anything below 105°C is fine, a lot of people say that it shouldn’t run hotter than 90°C, what do you guys think?

No, 105c is very high and you should try to keep temps below 80-90c at load.

Can you post a link to where it states that anything below 105c is fine?

Too hot. Everything above 85° should take care of. The Card downclock and the lifespan could be reduced.

105c is when it will shut down to prevent any damage. It's not a healthy temperature to run the card at if you want it to last.

When I had a bug with afterburner that it locked the fan speed to 30%, the GPU would only downclock when it was above 100C

Actually, this is the temperature the card starts to downclock, never saw it shutting down when it got to this temperature

Try a manual 100% fan speed and give it a realistic stress like Unigine. No Furmark. If it's still too hot, you should try replacing the thermal paste on that cooler.

Even at auto fan speed it gets to 100%

[Funtron5000]

Well, if you can monitor voltage in Afterburner, is it going up very high or no?

85 Celsius is where I set my max

 

You can make your fans go faster to keep temps there

I can't test it right now but I don't think so

as was mentioned earlier, reapply the thermal paste

Yeah. My 760 never got that high and was overclocked to 1298MHz.

That's strange. The max safe temp for a gtx 760 according to Nvidia should be 97c.

GPU fan gets to 100% when running at this temperature, with both the case fans at 100%, I haven't seen any difference at all

Undervolt the GPU

Some time ago, I have overclocked it, around 1200MHz and 80C, I might try to reapply the thermal paste

100°! is the Temp the GPU starts to melt.

No, serious, everything above 80-85° is bad. You maybe have some serious Airflow Issues or you live in the Sahara.

And who told you the GPU starts downclock at 100°? Thats 100% wrong.

I don't think I have any airflow issue, but I might try to figure that out

As already mentioned I had a bug where the fan speed was locked at 30%, so as soon as I started gaming, the temperature would get to +100C and the it started to downclock, and I haven't seen any downclock with the GPU running at 95C

You are fine. You will not damage the GPU at 100C.

 

I am not sure why people seem to think that these temps would cause damage or reduce life span in a noticeable way. Remember that the CPU die is made of copper and silicon. Which have melting points over 1000 degrees celcius!

 

The concern with heat has to do with solder. High heat will melt the solder that makes up the electrical connections within the CPU. So that can be as low as 160 degrees celcius. But you will be perfectly fine at 100. As long as your temps are not hot enough to  melt the solder you are fine, and those temps will do nothing to reduce the lifespan of a die made of copper/silicon.

 

Just check to make sure thermal paste is properly applied and still in good condition, nothing more you can do.
