We remember the little experiment Pascal becomes passive: We are building a fanless GeForce GTX 1050 Ti (Eglisch: Modifying a GeForce GTX 1050 Ti for Passive Cooling), in which I – as i have done a few times before – narrowly failed a completely passive cooling. In the end, it was never without a generated draught. With the XFX RX460 4GB Passive Heatsink Edition and the Palit GTX 1050 Ti KalmX 4GB, two factory solutions are now available on the market that want to make this better.
But can something like this really happen? A specially designed heat sink can of course score with optimized slat spacing, but I am professionally skeptical and will test everything: the completely fanless operation in fresh air (Open Benchtable) and in the closed housing as well as with a housing fans (front, overpressure) or two fans (front and back, vacuum).
We also see that XFX and Palit take completely different paths in the radiator design in terms of the utilization of the airflow through the targeted use of the selected slat orientation. On the surface, Palit's map could only work with pure self-convection, while the XFX card might require some airflow.
But at the end of the day you're always smarter – me too. In terms of performance on paper, the Palit GTX 1050 Ti KalmX is clearly superior, of course, but that's not really the point. Before we start thinking about gaming, the parts have to work the way marketing would have us believe.
But before we start now and disassemble both cards as usual, the technical data comes here quickly as a mental way:
Commissioning and technical data
Test system and methotik we have already described in great detail in the basic article So we test graphics cards, as of February 2017 (English: How We Test Graphics Cards) and therefore only refer to this detailed description for simplicity. So if you want to read everything again, you are welcome to do so.
If you are interested, the summary in table form quickly provides a brief overview:
