I procured the above case with 2 fans on ebay for less than 10 € !
- without it, but with a large passive radiator, I could monitor up to 65°C when using intensely OCPN in an ambiant of 20 °c ...
- with the above case, without powering the fans, : 55°C
- with above case when powering the fan in serial, 45°C, (40°C when idle)
- The performance can be further improved by connecting the fans in parallel, but it is not needed...
Why connect the fan in serial : each fan will pe powered in 2,5 V, which means more or less half speed and 1/4 of noise level !
I need to bring the case close to my ear to perceive it ! And that's not due to my age !
OK, I have to say that, for 1st start, I had to help the fan to turn with a gentle finger push, but that occurred once only, then they start to turn when the power is applied ...
I think I found the proper case for my on board installation : VALIDATED
