Howdy there.

I have just done a 15 minute benchmark in furmark to see how my graphics card is performing. Graphics card is running at 757mhz 88° and at 90% fan speed.

Playing Shadow of Mordor the results are around 50 fps average 83° 60% fan, speed core clock starts off at the 980mhz Boost but drops to 875mhz after 10-15 minutes of playing.

Is it just me or are these results a little poor considering the card is factory clocked and running so hot?

Any help greatly appreciated. Happy to provide other system details also if this helps.

The normal target temperature for the GTX 780 Ti is 82c (check your monitoring software under "Temp Limit"). That's the temperature at which your card attempts to maintain while gaming. It will raise and lower fan speeds, voltages, and Turbo Boost clocks to stay right at 82 or 83c, just like you are seeing. The stock clock of ~876 MHz will be your bottom limit during intense gaming. Your card is operating normally, as designed. With fans at only 60%, you're actually doing very well with some headroom to spare. 70%+ is very normal in the middle of a hot summer playing games that push your GPU usage up to 90%+.

Hey thanks for the reply, should have good airflow in my case. Have a front 200mm intake a rear 120mm exhaust and a top 200mm exhaust. CPU cooler is a noctua NH-D14 with the fans exhausting to the back of the case.

Cable management isnt great but i have seen worse, mostly dust free. Filters are cleaned regular.

The card is completely stock i got it out the box and installed it obviously with fresh and new drivers.

NEVER use Furmark, use something like EVGA OC scanner or another GPU tester. Furmark is known to overly stress cards and potentially kill them. the clock also will almost always downclock because it just pulls too much power, and places an unrealistic load on it.

What are your ambient temps in the room?
What 780ti is the card specifically?
Does it have a reference or aftermarket cooler?

Thanks for the reply :)
Ambient temps are around 20° maybe lower.
My Card
Reference cooler.

Ran EVGA OC Scanner for about 30 mins at the 1080 preset at 4M particles, results were similar to when playing Shadow of Mordor.

If i am being picky just let me know, i just expected the card to be at-least able to achieve its boost clock without running so hot. Maybe i am just too picky :p

Something is up, because superclocked cards can come with reference coolers and theyre around +100mhz over stock.

It is idling at about 47-50° at the moment which again seems high.

Not sure if this helps but if i do a stress test for my CPU it maxes out at about 68° per core running at 100% load but that is with an overclocked to 4.3Ghz from 3.3Ghz (i5-2500k).

Maybe that gives some indication of the air flow in my PC.

What is the brand and model of your GTX 780 Ti ?

If it's a reference card, with stock single axial fan, they target 80C. Typical is 80C--85C. With only 60% fan speed, there doesn't appear to be any issue with the performance of your card.

Now if it's any kind of after market cooled card, would expect it to run about 5C--10C cooler that listed above.

My Card

Thanks for the reply. I wanted to overclock it but if it can only achieve stock core speeds at 83° i wont bother until i get it water cooled.

You can still OC that card, since your Only at 60% fan speed, but its going to be pretty loud. When your at 100% fan speed, and running 80C to 85C that's your limit.

You can try one of the NZXT brackets that allow you to use a closed loop CPU cooler on the GPU. Great temps n lower noise, but for the extra money I'd return the 780Ti IF you can and get a GTX 980, more speed for about the same money as your 780Ti w/added close loop water cooling.

Yeah have been checking the G10 bracket out for the last week. Have been considering that a H110 and some heatsinks for the VRM would be very nice :). Sadly i cant return the card now as i bought it three months ago now.

Such a shame they dropped the 980 so soon after i knew i should have waited :(

Thanks so much for the help mate!
