asrock x58 deluxe fan headers and chassis fans

[ptolamy]

Hi this mobo has several 3 pin fan headers but i am unclear as to whether these are...

1. to power the chassis fans
2. just to read rpm data from the chassis fans
3. or both?

Can anyone help me? They are labeled CHA FAN 1, NB FAN, CHA FAN 2, PWR FAN.

Further to this, My chassis fans only have standard 4 pin molex power connectors. Does an adaptor exist to have these speed controlled from the mobo (and bios, or internal temp)?

The bios has spaces for rpm reports from these headers, but they are currently greyed out (as one would expect)

Do I need to get new chassis fans with an additional connector specifically for the 3 pin headers?

Cheers if anyone can help on this.

Answer number 3. Both.

These headers are to provide power to the fans. They are managed by speed sensors and power controls in the motherboard BIOS. There are adapters for your Molex connectors but the better choice is to buy fans with connectors that fit the motherboard headers.
