So i just bought an extra FAN for my Hyper evo cooler.

its a 3 pin, I connected that to Sys_fan_3 ... and it works fine ..but the problem its that is at a constant 1461 RPM

while the cpu fan is 670rpm and rises as cpu temp goes up ..

i went into bios PC health status > 1st/2nd/3rd system fan control > manual > i changed to different voltage but my fan still at 1461 rpm
i even disable it, set to normal .. nothing happened .. still running at 1467 rpm

i even use easy tune to slow it down, but doesnt matter what speed i set it to and save .. it doesnt do anything

is there any other way to slow it down?

or even better set it to the same auto as the CPU fan? low rpm when temp is low and higher rpm as cpu temp goes up?

Thanks

P.S : whats better in a push/pull system, High speed push / low speed pull? - low speed push / high speed pull?
 
ok, so I installed my 3 pin fan to SYS_FAN1 ....and rpm dropped

but there is still a problem ... when i set it to normal (auto) ... it runs at 1000ish rpm
doesnt matter if im idling or running intelburn test ... it stays 1000rpm

however .. i goes up and down if i set it to manual and play with the voltage

any idea to make it work in normal .. same as the CPU fan?
 
Well 3 pin headers work off voltages and 4 pin connections from the CPU work off PWM. There should be an option for you to set the fans to voltage mode vs PWM. If I am thinking about this correctly you might be able to over ride the PWM fan to run off voltages like your 3 pin rather than off the PWM settings. That would get them similar maybe not equal.
