These are some of the mods I made to my Yong Heng. I borrowed a lot of ideas from other YouTubers. This is still a temporary setup so can test if the ideas are going to work before I fix everything down in their final positions.
Initially I wanted to make a closed loop setup so I wouldnt have to use ice but without the ice the system temperature would only stabilize over 70C. With the ice it stabilizes at 64C. Still working on it.
