Phobya PWM 8x splitter

[CCISolitude]

Hi all,

Having had some excellent suggestions and advice from folks here, I thought I'd come back for more!

I recently picked up 6 BitFenix Spectre 120mm PWM fans for my radiators.

I also picked up one of the Phobya PWM splitters so that I could run them all and have the motherboard (Asus Formula VI) control them.

So far so good.

Except, it doesn't seem to do the job. The fans are at full speed all the time.

Now I've checked the board channel itself with a lone fan, and it regulates the speed with no problems.

Any suggestions?

Which fan header are you using? The CPU or one of the chassis headers? You may be able to switch between pwm and DC control on the headers in the bios... It might work changing it.

Hmm, I'll go investigate, see if I missed an option.

Nope, its Q-Fan Enabled/Disabled - nothing else.

Have you installed AI Suite (software)

Or tried a different port on the board?

Are the fans you are using 4 pin too? I cba to go searching google - you could have posted a pic or more details in the OP

Yup, tried the software - turns out the Chassis headers aren't true PWM, only the CPU and CPU Opt are.

So got some extension cables, and as of 2 hours ago or so, it's doing what I want it to do.

Now I just need to find the right balance for thermal/noise limits
