The gap (arrow) is the particular reason why TEC side can't have thicker than 1/8" insulation [...as it will start touching the heatsink otherwise]. Regards


Note: Coldplate as it appears before most of the neoprene is applied

Improved neoprene insulation specs are as follows; thicker insulation and better edge coverage will prevent edge frosting seen earlier. Regards

Improved RJ45 connectivity between PSU (power supply unit) and the cooling module was one of the remaining items and is going to insure clean power and signal integrity.


A lot of thought went into selecting following RJ45 cable...

  1. Length (3 meters for optimal distance between components)
  2. Shielding (for signal integrity, clean power/signal and interference prevention)
  3. Gold contacts (for improved connectivity)
  4. Color (for visibility in the dark)
  5. Flat (to prevent tangling)
  6. Etc.

Following desiccant is what I am considering as dew-prevention and anti-fog measure for high humidity and even for low humidity environments where cooling might encroach upon dew point. These are designed for cameras and I don't see improvising or fitting to a DSLR an issue. These inserts are also re-chargeable. Reflections should not be a concern if properly shielded/placed.

Ant-vibration measures... [Maglev fan is at the core of it]


Note: I'll elaborate on zero vibration guarantee in coming posts since there is lot more to it

Bolt is probably the only point on the TEC side the is prone to heavy frosting; will need to be insulated after installing...

PSU assembly quick test with production cable lengths, insulation, etc. White cable is Cat7a shielded (SSTP) gold (3 meters).


Some camera tests soon. Other testing participants welcome!


Note: All readings are actual; camera didn't capture red displays properly which are quite clear and discrete in real!
