Fan headers vs Fan controller for 4x fan radiator

so I have 4x sp120 high performance and I need something clarifying as I have had mixed opinions??

a) Do you connect the 4x fans to the motherboard and use software control ? b) Do you connect the 4x fans to a controller and allow software -- corsair link to monitor temp and you adjust fans manually?

I am using the h100i

thanks

The problem with manual controllers is well, who wants to pause in the middle of an intense battle to mess with the fans...

I found this 4way splitter that allows you to connect 4pwm fans to one header, while supplementing power via a molex connector if you are worried about overwhelming your header. So you get all the control of PWM, and all the power of Molex.

I hope this has been helpful.

Just connect them to the motherboard in my opinion. If you've got PWM fans then you can set up the fans in the bios (if connected to 4-pin headers). If you've got an ASUS board you can use their very nice Fan Xpert software which works with 4 pin and 3 pin fans.

If you wanted, you could even get a fan splitter and hook all of those fans up to one CPU_FAN header. Corsair SP120 fans are rated to run up to 0.18 amps max, and most CPU_FAN headers can supply at least 1 amp. Whether or not you can control them if they're 3-pin fans though depends on the software you use. I don't know much about software fan control except for ASUS Fan Xpert, which is motherboard-specific and changes fan speed by modifying voltage on the header, just like a fan controller, only now it's automated - you can set it up and it will do all the controlling for you instead of you turning knobs like on a normal fan controller piece.

thanks guys - I am using an Asus Maximus VI Hero motherboard so the Asus software sounds good.

Also that 4 way splitter looks very good indeed - In total i will have 4x sp120 in push pull config on a h100i (atm) and another 3x Af120 and an Af140 in the case.

Do I need PWM fans really if controlling through software ?
