Two fans one Splitter

[AgahPT]

Hi,

 

I've begun upgrading my case with some new fans and i bought some PWM Y Splitters, I know that i can only monitor one of the fans connected to the Y.

 

My question is: Does it make sense to buy NON PWN fans (about 40% cheaper) to attach to the non monitored Y connection since the monitoring wouldn't work anyway.

 

The final configuration would look like:

Yes,But speed control won't be possible unless,your mobo supports voltage control

if it get's to loud you can do this.

I'll be using my MB (ASUS Z87-PLUS) headers and AFIK the only "real PWM" headers are the CPU and CPU_OPT headers all the others just shoot 5V over the 4th pin. 

 

Can anyone confirm this?

4pin is probably all PWM because you can plug a 3pin fan in a 4pin connector and vice versa. I don't think that 5V is the voltage it outputs. most fans start above 6V and the nominal voltage is 12V

I better stick a multimeter there to check that out for real
