Test Results: Fan Speeds & Temperatures (Mining & Gaming) & Conclusion
The following charts depict the maximum fan speeds and temperatures measured during each of our benchmark runs: gaming, FurMark, and Ethereum mining. These should give you an idea what happens when you tax your graphics card in various ways. (Although we do have lab-grade noise measurement equipment and hemi-anechoic chambers capable of providing a >6 dB(A) noise floor, they're located in Germany and Greece, so we're still working on duplicating those setups in the U.S. lab.)
Thanks to its superb cooling solution, MSI's GTX 1070 Ti Gaming registers the lowest fan speeds of all the cards we tested. Subjectively, it's also the quietest. On the other hand, Nvidia's Titan Xp and GeForce GTX 1080 Ti look to be the loudest in every workload, from mining to gaming.
When it comes to mining, the Galax GTX 1080 EXOC also demonstrates low fan speeds. However, its performance is low too, due to GDDR5X timing issues faced by all GeForce GTX 1080 cards.
The GeForce GTX 1070 Ti Gaming not only demonstrates the lowest fan speeds, but it also achieves the lowest operating temperatures. It might not take first place in performance per watt, but the card is ideal for stressful applications like mining because of MSI's highly capable cooling system.
Fourth place is occupied by Nvidia's GeForce GTX 1060 6GB Founders Edition, our performance-per-dollar winner. This card would be our top recommendation in a world where graphics cards were still selling at their recommended prices.
Our Conclusion...For Now?
Card prices remain stratospheric, of course, and availability remains so spotty that strong recommendations made one day get quashed by the market realities of the next. However, as we noted above, for the time being our top Ethereum mining card of the moment, ignoring that concern, remains the 6GB GTX 1060 Founders Edition. It didn't have the fastest hash rate, nor the coolest running temperatures, of our Nvidia test lot, but it's strong in a relative sense in the areas that matter most when mining. Results per dollar--both in terms of card cost and power consumption--make it hard to ignore.
