I think I'd posted a few different threads over the past two months or so.
My NH-D14 system is well-cooled. It got better when I replaced my Noctua fans with an Akasa Viper with no increase in noise. I eliminated two fans out of six in that upgrade. Then, I decided to replace my very good Panaflo [103CFM/2500RPM/~0.50A] exhaust fan with a PWM. I wanted PWM because I THOUGHT I had a defective motherboard 3-pin [thermally controlled] port, and decided to put two fans on a PWM splitter powered off the PSU. This would then let me run my NZXT 200mm fan from the now-free 3-pin port previously feeding the Panaflo.
But the only fan I could find to replace the Panaflo was a 140mm Viper unit, and I had to kludge together an adapter and duct to the case rear (120mm). So far, so good: the pressure is lower, but the noise is also lower, and the airflow seems to be just as good. It was good because the NZXT is still pushing something proportional to its rated 166 CFM into the case.
Now -- I find that my second CHA_FAN2 port isn't defective. It was the fan patch connector I'd used to test different fans on that port, so I concluded the port was the problem.
Now I have every single fan thermally controlled, including my 200mm CM front case fan. And I can monitor all these fans except for one of the Vipers, and I could do that by running its tach wire to either CPU_FAN_OPT or PWR_FAN.
And I looked at the configuration that I had created, and I was pleased. All the fans run so quietly at idle that you can't hear anything. at pre-sets between 40 and 50C CPU temperature, they ramp up in speeds until they're running 100% @ 60-65C.
So the question: If fans are controlled to spin at 30% to 50% of their rated top-end for most of their usage, will they last longer?
I would guess so, but maybe someone knows something I don't.. . .
