Fan connectors question

[iglisca]

Hi,

I have a msi h100m mobo and i thought it has a pwm fan connector so i've bought a noctua fan for it. However after reading the manual it is actually a voltage mode fan control.

Now here comes my dilemma. For the moment i have 2 3pin fans connectd with a splitter to the mobo.

Should i keep the noctua fan? Is it still worth? Doea coltage control works with 3pin fans? (They're connected with a pwm splitter that came with the noctua) or do they work full speed?

I could return the noctua and get a molex splitter for 4 fans (2x5v 2x12v) and run intake at 12v and buy 2 more cheaper arctic fans and run them exhaust at 5v?

What do u guya suggest? My case is a phanteks p400 and i have the 2 stock fans

connect it to the 4-Pin header.

it's fine.

modern boards can control fans by voltage control just as good as with PWM
the times where voltage control meant 100%-70%-40%mode are long gone

I only run 3-pin fans on my Gigabyte Z170 Gaming 7 and can control all of them just fine by the mainboard's software utility with individual fan curves.
I'm sure the MSI will be capable of that either.
