There seems to be an undesirable noise present in my otherwise-silent MX Zilent switches. I believe this noise is caused by wobble / play between the stem and the housing, especially the switch top.
I have found that using Outemu Ice v2 tops that I bought from u/hbheroinbob back in January helps. These housings are very tight-fitting compared to other switch tops, particularly in the vertical direction, which I believe is the main source of the noise.
I have compared a few, and these Outemu tops are tighter than Gateron, black Cherry, retooled black Cherry, Cherry RGB, and Razer tops.
Thing is, even though they improve the ticking noise for me a lot, they also introduce a scratching noise. I have found that lubing the tops lightly with a thick lube solves that, however. I lightly painted on some Krytox 207 on the top and I don’t hear any scratching noise after doing that.
Bad news if you are making MX Zilents is that these tops aren’t made any more. BUT, the good news is, Outemu is making a clear top that doesn’t have an LED cutout or hole, and this top has the same specs and should be just as anti-wobble. They might even sound better since they don’t have a hole / slot in them!
Here is a video I took demonstrating the noise and the “fixed” switch with the Outemu top. I really like the sound of the Outemu top better but I would say make sure to lube it!
This can also serve as an introduction to me, my voice, my hands, my flimsy desk, my cheap hotswap keyboard, etc.
