Bit more live action before the weekend, decided I wasnt 100% happy with the ECU caddy with only four fasteners for the lid, plus the lid was a little flimsy, so redesigned the lid, added two more fasteners and some extra bracing around the edges and middle, also printed it this time in PETG instead of ABS. The PETG had much less warping and ended up a nicer overall print.
So that's now in the cupboard waiting for final wire / install. My fan also arrived for the condenser so spent some time figuring out the best way to get that on the condenser, in the end I went with the good old fasioned constant pressure fastner method (aka springs).
I also ran a foam seal around the outside of the fan to help seal around the shroud. I'm not going with a complete cover fan shroud on the condenser as I want as much airflow through/past it as possible for the rad and intercooler behind it. The rad will have a shroud made up and the biggest thermo I can fit on it.
