I don't understand; You say you don't want any control, Then you say you want them to sit at the minimum PWM speed.
If you are using minimum PWM speed, you are controlling the fan speed. Without control, PWM fans run at full speed. But that's the tip of the iceberg, I don't understand your philosophy.
You buy a fan that is made to be thermostatically controlled, then you use this control feather to turn it into a slow fan that will not react to protect the computer from over heating.
Why not just buy slow cheap fans to start with. That way you can use the money you save to help replace the parts that go bad when you burn up your computer.

Mine is set to run quietly (50%), but a hurricane goes through my CPU cooler if it reaches 150 degrees Fahrenheit. My CPU fan is 38x120mm with 135cfm at max speed. Each time your CPU overheats, this takes at minimum, few months of its life away. The only time I ever hear the fan is when I run a CPU burn-in program.

I had some high speed fans I bought a while ago and wanted to use them in a HTPC. They kept throttling up every minute because the cpu temp was "spiking" to 40c for a second when a script runs every minute, and the mobo I was using didnt have a manually adjustable curve.

Regardless, I came across some new old stock 800rpm GTs and just swapped them in.

So in your opinions would I gain much cooling benefit going from a storm scout 2 to a enthoo pro ?
I'm running a air cooler and a none ref gpu
Also anyone with the pro able to measure distance from end of the case to the first bottom fan position so I can see if I can put 2 fans in the bottom with my bulky psu
Thanks

How is your Scout setup now? You might find the cooling links in my sig helpful.
Probably a little better. But a few simple mods to your Scout would make it quite good.
Removing the HDD cage with 2x front intakes there would make a big difference.
Adding an intake in the 5.25" bays also gives better airflow to CPU cooler.
Bottom intake with case raised so there is 35-45mm bottom clearance for good airflow to bottom fans
Remove all unused PCIe slot covers from the back to improve exhaust airflow.
A few good case fans and possibly setting them up with automatic control using motherboard and GPU temps would probably make a world of difference.

I have removed both middle h/d cages . I have 2 jetflo 120 in the front as intakes rear jetflo side jetflo exh and top exh sickle flow didn't notice a diff when it was intake.
No room in the bottom for a 120 fan psu is to big

I did read your articles just couldn't find a solution going to swap some fans around this weekend and try 2 frt intakes 2 side intakes 1 rear and top exh unless u have any ideas if I can get my pic to post u will see my layout

To really be able to help I need to know the room temp, component temps and cooler intake air temps.
The component intake air temp andcomponent temp shows us how well the cooler is working.
The room temp and cooler intake temp shows us how well the case is supplying cool air to component cooler.

Ambient temps 24deg c cpu idle temp 30 load 70
Gpu idle 28 load 71-75
I don't have temp sensors in my case to measure air intake temps but as soon as the load is stopped temps drop rapidly . I think air turbulence is my issue and my case setup can't get the heat out quick enough

One of my (not very old) fans has developed a rattling noise @ certain RPM. I guess the bearing is stuffed.
It is mounted horizontally, I think I read somewher thasm most fans are happier vertical?
What sort of fan, or fan bearing, should I be looking for to run horizontally? 140mm, pref PWM. Needs to be quiet / silent at lower speeds, and capable of moving lots of air at higher speeds.

Those temps are not too bad.
Especially if temps inside of case are5-10c warmer extended load runs.
How long does it take for system to reach maximum temps under full load?
If more than 3-4minutes, your case is most likely not exhausting all of the coolers' heated exhaust and cooler intake airflow is being heated up by it's own heated exhaust.
