GPU Tempurature. How hot is too hot?

[DELTA9]

I am fairly new to mining and need to know when to give my card some time to cool down. My GTX 750 is currently running at about 45 Celsius. Will my card shutdown before catching on fire or do I need to monitor the temps?

[Amph]

45 is a joke, too hot is 90, but better not to go above 80 imho

[Equate]

for 45°C who creates a thread lol ? My gpus are running at 89°C

 45 C ? You got to be kiddin' me!

Hahahahaha OK thanks.

Only worry when it gets around 85 to 95 C. Your card is running really cool, are you even mining with it?....LOL

Uh... 45oC is about the temp my cards idle at w/ 100oF ambient or so.

I only run them up to 80oC max, most are around 70oC, by making liberal use of undervolting....  re: my 7970 can get close to 800khash at "optimum" settings, but I run it at 940 core 1200 memory & can drop the voltage to 1.00, it's showing max temp of 79oC in Afterburner (after about 4 days), current temp is 71oC.  Same deal with these old 5830's, I could get close to 300khash but I get 230khash instead, running at 720 core 680 memory, at 1.063v instead of 1.163v.

I wouldn't feel comfortable having them at 90oC for a sustained period of time, even though they're rated up to 100oC.  80-85 or so would be my tops..

R9 290X - Scrypt Algo -> Stable 94 °C  not 93 or less or 95 or more, every time freezes at 94 °C.

the lower the better !

less power draw
less noise
less fan rotation
less heat

I run at 87 all day for 6+ months now. No problems.
