Yesterday i discorvered that i can use 3-pin fans on my MB (asus maximus vi hero) and control them like they were 4-pin PWM fans.

Used AI Suite's Fan Xpert 2 to do so.

I thought they could only be regulated by voltage. Why can do they act like PWM fans?

it's just how fans work, some motherboards can vary the voltages given to the fan connectors, and thus, even if you were running a 4 pin fan with a 2 pin connector, as long as the functionality is there, you could still control it just like you would using a 4pin connector (i use this example because this is what i have done and it works perfectly fine at all speeds)
