Bladerunner, Thanks for the feedback. I guess I've visitit your site about a hondred times
I like your style!
Zero fan is not my goal, maximizing performence is. And a lot of the performence out there is limited due to the heat. When it gets to hot, the life span is half, and lockups are regular.
Like you've stated, it's amazing to see how a spot that does not get warm with only a little bit of airflow, will be hot in a situation with no airflow.
A PAPST will not start at 7v, but you can turn it down to 5.5 once spinning. Airflow will be more weak, but there is some airflow. After sandpapering the blades the sound went down.
A PAPST like that, in a closed case, is for me close enough to silent. The same goes for me for the 12cm PAPST
This is also the reason why I use 3 rads, to be able to get enough cooling at alomst silent airflow.
I don't have the soldering/milling skills (and believe me, I've tried!) to make it like yours or petter. It only ended me up in killing expensive PSU's
Oh well, Once I have my system up and running again, I'll thing of something
