Noise levels and temperatures
Most normal versions of the GTX 1050 and 1050 Ti feature a so-called 0dB-mode, which means that the fans will turn off wwhen idling, however these low-profile cards do not have this feature. The Gigabyte doesn't produce a lot of noise though, so it still falls into the 'inaudible' category, whereas the MSI and KFA2 cards are quiet, but definitely audible.
Under load the noise level of the KFA2 practically stays the same. The Gigabyte card remains the quietest, while the 1050 Ti from MSI turns out to be the loudest card. The difference with the quiet 'big' variants is pretty significant, but nevertheless none of these cards can truly be called loud.
The GTX 1050 from Gigabyte is the hottest card out of the bunch, with a temperature of 74 degrees, but this temperature isn't high enough for you to worry about.
