I am buying a motherboard a ASUS Maximus V FORMULA and it only has 4 pin PWM fan headers and I want to know if it is possible to run a 3 pin fan on these headers.
 
Solution
Yes it's possible, maybe you will need to set the cpu fan header from automatic to advanced to support voltage control, but it will work ;).
It wont anyway....4 pin doesn't necessarily mean PWM .... at least according to Asus regarding their Maximus VI Formula, non but the COU_1 and CPU_2 headers are PWM ,,,, the others are all 4 pin but not PWM.
