@Ryosuke1208 Actually I do use liquid nitrogen a lot. However I have some chips that cold bug just below the range of dry ice. So it makes sense to use dry ice for those CPUs.
@lordofgonzo I went with the design change that lets you change the air pressure on the up-stroke. It lets you adjust the speed a bit. Not all that happy with it, and I'll probably play around with it a bit more.
