Hey [H], I've got an older build that I'm trying to tweak the cooling/dust collection on. I've got an Antec Air540 case with a full set of DEMCiflex filters (minus exhaust) and an Arctic Cooling 360 aio. The 3 (120mm) aio fans are in a pull configuration and the 3 non pwm stock case fans (140mm) are the exhaust. With the three 120mm intake/aio fans pulling air through the filter and then the radiator I am losing a lot of cfm's compared to what the three unobstructed 140mm fans are exhausting.
Intake/AIO fans
Stock exhaust fans
I have an older board Asus P8Z68-V Pro that only has 2 pwm enabled fan headers, 3 really but both CPU ones are controlled together. I have the 3 intake/aio (120mm) fans plugged into the pwm cpu header and they are controllable. I bought this pwm fan controller hub with the hopes of connecting all of the 140mm exhaust fans to the PWM chassis fan header and setting them low for positive pressure.
Unfortunately my plan of using that fan hub isn't playing out. While the 140mm intake fans have power nothing seems to change when I make changes in the bios, they are running at a pretty steady 1,000 rpm.
I'm wondering if anyone has any suggestions? Worst case I am just going to get some Zalman Fanmate 2 controllers, a sata to (3) 3 pin connector and set all all of the fans to low and see what happens.
Would I see any real difference if I were to switch to static pressure fans for the intake/aio fans? Switch the exhaust fans out to 120mm's? Remove an exhaust fan?
Right now I am running the intake/aio fans at 100% 1,450rpm just to not make the case a dust collector
Thanks for any help,
