We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. The motherboard is also passively cooled. This gives us a build with almost completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests.
We measure from a distance of around 1 meter from the closed chassis and 4 foot from the ground to mirror a real world situation. Ambient noise in the room measures close to the limits of our sound meter at 28dBa. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the video card. It also brings us slightly closer to industry standards, such as DIN 45635.
KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refrigerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum
The triple fan profile is set up to be slightly more aggressive than other GTX980 Ti's we have tested. The card is clearly audible under load, but it is not that intrusive due to the fan pitch which is a bonus. If you want a quiet GTX980 Ti then the Asus STRIX Gaming Direct CU III is without question the one to get.

At those temps, you can start making coffee with your GPU. I guess that could be considered a plus for some.
Here is tips Easy with kitgur’u ********* Here’s Tips
You can make coffee with cold water too but I myself want coffee water boiled like every coffee maker does, and in case you didn’t know, you need 100C for that in normal conditions. Also if you start pumping coffee water on that, it would cool the pcb and your coffee making procedure would act as a water cooling system.
You’re wrong on both coffee points. You can make great cold drip coffee, you just have to use different methods and have a bit of patiences – takes about 8 hours to make a litre of cold drip – and you should not use 100C water unless you want to burn your coffee and ruin all flavors. About 92C is the ideal water temperature for making coffee.
Ask any decent barista or coffee enthousiast and they will tell you the same.
Actually not. Coffee makers do boil the water and then cool it down, because of the mechanics in first point, so you don’t need a pump to get water moving and also because you want to kill bacteria from the water. Ask any coffee maker company and they’ll tell you the same. I didn’t know about 8h coffee things so sorry about that, but could you not make that coffee with any gtx980ti?
Ah, but then you deal with home devices (and I actually do that too, just use the kettle to boil to 100C and then cool down). If I go for a filter coffee, my barista has a water heater that never boils the water, but keeps it at an almost constant temperature just below 100C. And he lent me a kettle once that did the exact same thing. Not sure about his espresso machine though.
And I guess any powerful video card when run at a high enough load can be used to boil water and make coffee. I feel like this would make an interesting casemodding project 🙂
