Hi Guys,
I could use someones expertise in fans connection via DC controlled via voltage vs PWM.

When I first started water-cooling, probably 12-15 years ago I have built substantially large system. All of my fans, pumps where controlled by aquaero 6XT and additional Poweradjust 3. I started and end up using only 3pin cables via DC (power control) and I'm still using then till today. Now years later I have switched to air-cooling but still using aquaero 6XT to control all of my fans and I'm still using most of the same cables just adjusted the length.

My system fans are all Noctua NF-A12x25 ( 2x cpu, 2x front intake (Y-split cable) , 2x bottom intake (y-split cable) 1x back, 1x top exhaust) all are set to run via voltage to run at min. speed (43%) for maximum silence and rum pup according to my custom curve.

I have been thinking for a while now to switch all of the cables to 4 pin which I have never used before. I've heard with PWM you can set precised fan speeds, even lower RPM then via voltage, but that is why I'm asking if its worth for me to bother messing up my setup. Are there any true benefits and whats the possible drawbacks.
Thanks

From the sound of it Its not worth the hustle. I have been running aquaero 6xt with aquasuite and all 3pin cables from the beginning and never failed. My goes is to archive as quiet PC as possible and I think its already silent. Sometimes trying to making things "better" doesn't always go that way and when it backfires, you wish you wouldn't touche it and I think I will do just that.
Btw. I just lowered % of my Nocta's fans from 42% to 39%, it makes a quite a bit difference in silence, yet still spinning and giving nice airflow

Thank you

Question. Can you create a fan curve using DC voltage or is it just set and forget?

Yes you can, that is how I have been running since I can remember.
