Test results custom-cards (noise levels, temperature, power consumption)
Below you can find the test results of the Gigabyte, Inno3D and MSI custom-cards.
In idle the Gigabyte GT 1030 OC is clearly audible (although it is not annoying - but still audible enough which is why we would recommend it for a htpc). The other, passive cards are practically inaudible - the shown value is the bottom of what we can measure in the soundproof box. The good news is that we do not measure any coil whine or other electric noise.
The image changes under load, all cards show a considerable increase of noise levels. Considering the passive cards do not have a fan, it has to be some form of electrical noise here, such as coil whine. Because of the very low volume it is practically impossible to hear - after all we measure at a distance of 10 cm from our open set-up. In a regular usage scenario the card will be in a case and at a much greater distance. Of the thee we would still choose the MSI, especially with the Inno3D the increase in noise levels is rather big.
Looking at the temperature, it stands out that mainly the Inno3D gets quite hot under load. The 'Silent' Gigabyte card is a lot cooler. The fan of the GT 1030 OC of the same brand does not perform great in comparison.
Last but not least: the power consumption. The Inno3D and MSI cards are clearly more efficient in idle, the passively cooled Gigabyte card consumes a surprising amount of power. Do bear in mind that we show the power consumption of the entire system.
Under load the differences are too small to complain about, but the Inno3D is the most efficient card, albeit barely:
