Yeah I'm talking about PWW aswell.It's based off PWM, so there is some inboard logic to control the fan based of RPM. The fan controller will loosely base it off load, but primarily bases fan speed off of heat output. The Noctua fan though it spins less than the Corsair, I'm sure moves more air and has more static pressure. That being said, the Noctua fan will likely come on around the same time, but with a lower RPM (and thus lower sound output) as well as cool it more efficient. That's the whole reasoning.
Noctua having lower max RPM, means it would always spin at lower RPM than the NR092L would at the same load and heat output. Therefore the PSU would be running at higher temps and potentially shortening its lifespan.
Actually I found some real world data of both fans installed inside a SF600 which confirms it. The PSU is running hotter.
I see. I was hoping that maybe the crimps are the same on both headers.You can perhaps de-pin the NR092L, but you'd need new crimps for new connections into the mini-header, and the tool to do it. So you're better off doing the regular depinning method and making sure it works that way.
Nope, PWM does not change voltage. It's 12V all the time. It's only changing the interval at which it's delivering the voltage. Smaller interval means less RPM, larger interval means more RMP.PWM just varies the voltage doesn’t it? So 100% will be the 12v, which will max the fan at its respective RPM.
As for repinning, the cable length on the noctua fan is all of 1cm long from the body isn’t it? So an extension of some sort is necessary. UNLESS I’m just thinking of my recently acquired A12 x 15 Chromax...
Edit: Yeah nah, it has a decent length, ignore me.
100% means its delivering the voltage constantly, so the fans would spin at their max RPM.
Original NF-A9x14 cable is 20cm + 30cm extension and Chromax NF-A9x14 cable is 1cm + 30cm extension.
