I wouldn't count on factory lube tbh, if you're paying $1 per switch you're likely going to hand lube the switches anyways. I have the regular HPX's and would not recommend using them stock.
EvshrugI used Krytox 205 Grade 0 on the bottom housings and stems, Krytox GPL 105 Oil on the springs. You could also go Tribosys 3203 (which is usually recommended for tactiles since it’s thinner than 205 to prevent overlubing and losing the tactility) but I use 205 for everything and have no issues. (Just don’t overlube, if you shine a bright light on the application area and you can see a thin, clear reflective coat you should be good!) In this case with the HPX’s, I would also suggest you lube the leaf on the bottom housings (which is usually considered a sin on tactiles, but for me the HPX’s suffered from way too much spring ping - that wasn’t fully resolved even with lube).
ZR24I really appreciate the depth of this answer! I can write to similar lengths about audio, but I’ve only scratched the surface of mechanical keyboards!
Is Krytox GPL 105 a thinner or more viscous lube? And why lube the springs? I could be wrong, but I didn’t think they had friction against anything (other than pushing at the ends).
The center of my keyboard seems to have a more audible ping (or what I would describe as a ping) than around the edges, do you think lubing the lead would help with that?
EvshrugI am so sorry I must've missed the notification about your reply. To answer your question, 105 is a much thinner lube, as it is an oil instead of a more traditional lube. You lube the springs to eliminate spring ping or crunch, where you can hear the spring as you press down (either as a ping or crunch, although the names themselves are pretty self explanatory). As for the ping in the center of your keyboard, it really would depend on a lot of factors. Lubing would definitely help, but if you only hear it in the middle and not on the edges, it may be that something is making contact in the middle of your keyboard, for example the middle of the PCB hitting the bottom case. If you haven't put any foam or some type of soft dampening material at the bottom of your case, it may help to do so. You can also look up things such as the tape mod (also known as the tempest mod), and that may help the sound be more consistent across the board. Sorry again for the late reply, and happy holidays!
They have cherry mx style (as opposed to Kailh BOX) housings, so you should use a cherry mx style switch opener (they have four prongs). Many switch openers you buy will have both, like this one: https://drop.com/buy/kbdfans-x-ai03-2-in-1-aluminum-switch-opener
