My gtx 770 is crazy HOTTT... IT REACHED 80+ C

I should start charging every time I explain how Turbo Boost works. Your card, every GTX 770 by default, has a Temp Limit of 80c. You can check and confirm this in Afterburner or PrecisionX. What that means is that your GPU was designed to target exactly 80c as its normal operating temperature while gaming. Above that temp your card will lower its Turbo Boost clocks, decrease voltage, and increase the fan speed to maintain and stay at 80c. Below that temp and your card will ramp up more with higher Turbo Boost clocks, increased voltage, and lower fan speeds.

Note the Temp Limit is part of the overclocking/Turbo Boost parameters that can be manipulated through Afterburner/PrecisionX; it is NOT the same as the thermal threshold...

The Nvidia specs for a 770 states 98C is the max GPU Temp. Typically if you get up to 90C you can start to worry a bit. PS2 will run your card pretty hot so 80C is perfectly fine. Each card manufacture sets different fan profiles so some cards will run hotter but quieter and other cooler but louder at full load. If it's the OEM cooler this is the case many times. If it's an upgraded cooler you can usually expect better temps.

My GTX680 is essentially an OCed GTX770 based on it's clocks. I hit 80C at times even with a modified fan profile on a stock cooler.

So 80c is normal and expected...... on a reference card. Now, many people have been spoiled by their custom cards with nice cooling and high airflow cases. They rarely, if ever, see 80c on their GPU, but that is still the Temp Target for Turbo Boosts. Now, it is summer and apparently Planetside 2 is one of those games that'll push your card to operate at 99% GPU usage, so a higher temperature is to be expected.

We need to dispel the myth that 80c is alarmingly high, when in fact it is exactly the temperature at which the GPU was designed to operate.

There's really no reason to set a fan profile for normal gaming with a custom DirectCU card. All you're doing is increasing noise, and as long as you're below 80c, its not really impacting your Turbo Boosts either. If you are overclocking and trying to push your limits a bit, then a fan profile makes sense.

Now if your card is a reference design, and you want to see some better turbo boost clocks, then you can fiddle around with fan profiles and maybe raise your Temp Limit, but your noise levels will most certainly increase.

Overclocking with Turbo Boost involves increasing your Temp Limit, Power LImit, Voltage, and clock speeds. You'll get more performance, but again, at the cost of extra noise.

I'm not interest in oc... I'm ok with the performance. I m happy as long as my CPU/GPU doesnt get too crazy hot xD. It was my first time building a gaming pc; I'm inexperience and I get really paranoid when temperature jumps... Look like I don't have to worries about 80 C on my gpu.. Thanks

Nothing to see here move along....

Actually, since summer hit a lot of people have been posting about their GPU temps. Most of the time before I click on the thread I think, "let me guess, 80c right?". Usually, that's right on the nose.

I guess no one remembers the old AMD x1900xtx with the sucker fans. Out of the box it ran 100C gaming all day long without a hitch. Chucked on a thermalright GPU cooler, OCed the snot out of it, and it ran 70C or less all day long. 80C is nothing. HAHA

I was the proud owner of a GTX 480 (92c normal operating temperature) and a GTX 580 (89c normal operating temperature) before upgrading to my current GTX 780 Ti (83c normal operating temperature). I should point out that my case is a quiet case (Antec Sonata), rather than a performance/gaming case and the cards were all reference. I'd be happy to run at anything below 80c. 85c doesn't phase me in the least.

I just moments ago got on a thread where a guy wrote that his card was running "super hot". How hot? 65c-70c!
