Where did you get yours from?
Mine is still backorder.
Some updates from my side:
I should finish to transfer my NB/SB and MOSFET blocks to their own loop today or tomorrow.
I'm still working on insulating the blocks, too thin and it's not enough insulated, too thick and it impedes airflow. (more on that later)
I tried some cheap 38mm fans for push/pull but those cheap fans don't undervolt well and were ticking horribly. I'll try to get real Panaflos instead. In the meantime, I got a Kaze Master fan controller that will allow me to connect my own air/water temperature probes to an external display. What CoolIT uses as coolant temperature is really the block surface temperature.
My take on insulation:
The chiller seems to be made to operate mostly over ambient temperature. The blocks are not insulated to act as heatsink and dissipate the heat that cannot be removed by the TEC. The TEC can only handle a specific amount of heat, unlike radiators.
So a perfect insulation would make the chiller fail if it goes over ambient.
A thin insulation (2x1mm Norprene tape) is enough to at least insulate the temperature sensor from the open air. The water temperature appears higher but more stable, less jumping around up and down.
I've still got my other idea to try out, to build a tight box around each FZE to increase static pressure in push/pull configuration. I don't know when I'll have time to complete it though, I've got a big research project to finish at work and it fills almost all my time, even free time.
If I had to recommend some mods, they would go in order:
1. Additional chiller or rad
2. Replacing the pump
3. Replacing the waterblock
4. Additional fans
5. Insulating the blocks
I really think that I'm close to maxing out the mod possibilities of the FZE. I'm not even sure how I would get another 1-2C better temp besides adding a 3rd FZE or a Boreas or even better, watercooling the TECs.
