I'm wondering if anyone has an ideal solution for my predicament.
I've purchased 3 Noctua A14-ULN fans as case fans for my system. I have 2 in the front of my case for intake and 1 at the rear of the case pushing air out.
My problem: The two fans at the front will not start spinning (they just twitch) unless I set the fans to 85% RPM on the motherboard. I've attached the Low Noise Adapters which brings the RPMs down to about 620, but that is still way too high. My case is extremely cool and with the RPMs that high I can faintly hear some noise (which I do not want to accept).
I'm wondering if there is some way to burst enough power to the fans to get them spinning, but then reduce the power significantly so the RPMs drop to around 300. I have looked and searched on my motherboard but I have not been able to find anything that will allow me to do this. I understand there may be a software solution; could someone recommend one? Preferably one that is not annoying, automated, and easy to set up?
Regarding the fan at the rear of the case, I have that fan set quite low - to approximately 40% RPMs. That fan also does not spin at startup but gets going 20-30 seconds after bootup. I figure the air coming off my cpu cooler is helping to get that fan started.
Any tips/suggestions would be very much appreciated. Thank you
