Temperatures are important to enthusiasts and gamers, so we took a bit of time and did some temperature testing on the NVIDIA GeForce GTX 780 video card.
NVIDIA GeForce GTX 780 Idle Temperature:
The NVIDIA GeForce GTX 780 video card had an idle temperature of 24.0C in a room that was 22.0C (72F). Running at nearly the ambient temperature is very impressive. Keep in mind that the NVIDIA GK110 “Kepler” GPU has over 7 billion transistors!
NVIDIA GeForce GTX 780 Gaming Temperature:
When playing Far Cry 3 and Battlefield 3 for about 30 minutes each, we hit 65C and did not get any hotter than this. The EVGA ACX cooler does an impressive job keeping the GeForce GTX 780 Superclocked card running nice and cool. Notice the fan speed went from 1300RPM at idle to 1860RPM when gaming. You really can’t hear the card with it in your system at idle, but when you start gaming you can hear the fan a bit. Notice that the GeForce GTX 780 Superclocked card is hitting 1123.5 MHz on the core clock when gaming thanks to NVIDIA GPU Boost 2.0 and these nice low GPU temperatures!
This low idle temperature makes the EVGA GeForce GTX 780 Superclocked w/ ACX Cooling the coolest running card of our test group at idle! Not bad considering the MSI GeForce GTX 770 Gaming card is in there with the Tein Frozr IV GPU cooler and so is the ASUS GeForce GTX 770 DirectCU II OC Edition. These cards have popular CPU coolers and are on a GPU with a lower TDP and still don’t perform as well as the EVGA ACX Cooler. At load the ASUS DirectCU II cooler is at the bottom of the chart, but the EVGA ACX Cooler is the next card in line.
We recently upgraded our sound meter to an Extech sound level meter with ±1.5dB accuracy that meets Type 2 standards. This meter ranges from 35dB to 90dB on the low measurement range, which is perfect for us as our test room usually averages around 36dB. We measure the sound level two inches above the corner of the motherboard with ‘A’ frequency weighting. The microphone wind cover is used to make sure no wind is blowing across the microphone, which would seriously throw off the data.
The new GeForce 700 series cards are much quieter than what we had on GeForce GTX 500/600 series cards, so it’s not a big shocker that the GTX 580 and GTX 680 were at the top of the noise charts. The EVGA GeForce GTX 780 Superclocked wasn’t the quietest we have ever seen, but the new cooler doesn’t sound bad at all and is not overpowering.
