Recently bought a newegg abs computer, yea, i know, but 1150 for a ryzen 5 3600, 2070 super, 16gb 3000 ram, 500gb ssd, partspicker was 1125, so yea. Anyhow, with the cpu cooler it came with it was getting it up to 90c, idled at 55, and gpu would get up to 80c and idle at 40. So i got a thermaltake 240mm aio, installed it easy as, the old thermal paste was applied terribly, only on 2/3 of it and squished out the side. So now gaming peak cpu temp is 55 with little spikes to 70 max, idles at 35, and gpu is 65 max, idling at 35.
I mounted the radiator to the top with the fans blowing out through it, it was just passive intake with the cpu fan blowing at the glass. It has 3 front intake fans and 1 rear exhaust fan that came with it, hooked up with the pwm and controllable.
Problem is, the radiator fans and pump are 3 pin, 100% actually isnt too loud really, they're only around 1800 rpm, i can hear the gpu fans running louder at just 50% when they come on, but i figure i can dial it down a bit for idle times. I just cant figure out how to switch it to dc so i can use argus to figure the minimums and whatnot. From what i understand, i should be able to switch it to dc and use normal fan controller software, no?
Another thing i noticed when checking air flow at idle, my rear exhaust fan is now at a weird perfect negative pressure balance where air is just barely moving into the bottom of the fan and out of the top, fan spins properly though, and when it gets warmer and the pwm ramps up the air comes out on top and bottom. Just wondering if that could cause a problem somehow.
So, if the b450m/ac doesnt have a way to switch to dc, are there fan controller modules that can be hooked up and controlled with software or something like that? I've found some that have a high/med/low switch, but i'd really like full software control
