The power supply is by far the loudest thing in the chassis. But the other fans are also starting off quietly and then after a minute or so revving up to full power. They are still a good bit less noisy than stock (the new fans only, not the new fans plus the super loud PS), but I am wondering why they are revving up. Nothing in the chassis is warm to the touch. No board, chip, etc.
After all of that, I took the cover off the PS and disconnected the fans, leaving the PS cover off so it can get cooling from the fans blowing right over it. It starts off whisper quiet, but just like before revs up after a minute or so. This revving up also doesnt seem to be dependent on anything other than time from bootup. If I disconnect the power and reconnect, they go back to whisper quiet again until the same ~1 minute or so and rev up again. Also at the exact time they rev up, the amber light below the top green light is lit and stays on solid.
This behavior is the same whether the PS fans are connected or not, so that has nothing to do with it. The behavior also seems to be the same no matter which fan headers I connect, except the far right headers. It seems whatever is connected to those spins up to full speed right away every time.
Which fan connectors are supposed to be connected? Does it even matter as long as 4 fans are connected?
And per a previous post, I am assuming this is the pinout:
Black = ground
Red = 12v+
Yellow = RPM readout
Blue = PWM (fan speed control)
If I were to pull either the yellow or blue and keep the rest connected, could that keep the system from being able to spin the fans up?
