Advice: Fan controls; Motherboard (PWM) or Manually?

[Ragingsilver]

Hi all,

I'm in the process of moving my old motherboard and parts into a new case (Define R5) however today I stumbled into a blocker.

My motherboard (Asus P8Z68-V) is quite old and so it only has the following:
- One 4-pin Cha_Fan1 connector
- One 3-pin Cha_Fan2 connector

I'm going to replace the case fans that came with it with Noctua ones. However I bought 3 (NF-AF14) and so only one of these fans can go on the Cha_Fan1 connector. I'm sending two of them back to get the FLX addition of noctua as they're three pin connector which will go on the Cha_Fan2 connection on my mobo.

Question is, should I let the mobo control the fans? Since Cha_Fan2 isn't PWM will this one just blow at 100% the whole time?

The other option for me is to replace all the fans with 3-pin ones and then use the case fan controller inside and control the speed manually.


Thanks in advance for any advice given.

you could buy an adaptor to plug the 3 fans into and then plug the adaptor into the 4pin. should allow all fans to be controlled by the 1 header.
