Gigabyte B450 Aorus M Strange Issue;
I just built another computer and now fine tuning the overclocks, voltages, ect.
I'm working on air flow in this tiny Corsair 88r case, Hooked up 2 fans for intake up front directly into the power supply with the molex cable. Hooked up System Fan 1 to the rear fan for exhaust.
Everything runs fine, Ryzen 5 1600 3.85GHz at 1.2-1.25 volts easily, 24hour Prime stable with the stock cooler, never saw past 74C.
I thought I could improve those temps a little bit by installing another exhaust fan since while gaming the GPU does heat up the inside of the case quite a bit, I go to plug in another fan to fan header SYSTEM FAN 2.
This is where I run into problems; I shutdown the computer and it lags, monitor turns off but computer remains running, Hard shutoff and go to reboot; try to get into BIOS and it goes there but Keyboard inputs and mouse inputs are incredibly laggy, doesn't want to respond.
Feels like something isn't working, I bump the voltage up on the CPU thinking it could be that, turns out its not, Return all settings to Default in BIOS and nothing still the same, PC boots up and runs okay no problems, go to shut it down and same thing, monitor turns off but computer remains running, have to hard shutoff everytime pushing the power button. Go back into BIOS and keyboard inputs are non-responsive.
Here's the funny part; I go to disconnect the second exhaust fan from SYSTEM FAN 2 header and I'm back in action, no issues, everything is normal, overclock sticks, shutting the computer off is normal, going into BIOS is normal.
Anyone ever ran into this issue? I'm guessing it has to do something with having power drawn from SYS FAN 2 header with a fan in it.
Now here's another strange thing about it; When I plug in a 3 wire FAN into SYS FAN 2 header; its normal no issues, but when I plug in a 4 wire FAN into SYS FAN 2; I get this issue.
I can live with it since the problem only exist when a 4 wire fan is plugged into it but with a 3 wire fan its completely fine. Just looking for someone to chime in if they know what this problem may be.
