mini itx mobo with more than 2 true pwm fan headers?

[susdu]

is there such a thing?

Do you need independent headers? Otherwise there are pwm fan splitters.

How many fans can I ran from a single header? Current wise

[ggumdol]

No. Not that I'm aware of. Asrock ITX motherboards provide only 2 genuine PWM headers.

is there such a thing?

Depends on the MB. It's usually specified somewhere in the manual.

There are PWM splitters that use a standard 4-pin molex (PATA hard drive power) connector so you don't have to worry about how much the MB can supply.

2 Electrical Specifications
2.1.2 Current
Steady state operation fan current draw (with 12.6 V applied, with fan operating in the free stream
condition) shall not exceed 1.5 A.
Fan current spike during start-up operation (with 12.6 V applied, with fan operating in the free
stream condition) shall be allowed to exceed 1.0 A, up to 2.2A maximum for a duration of no
greater than 1.0 sec.

I would interpret the quote that up to 1A is safe load, just to be on the safe side.

Thank you all for the info. PWM splitters it is.

Asus P8Z77-I Deluxe has two true PWM fan headers, and no DC control

Came here via google wondering if anyone knows of a Z97 mini ITX board with more than one true PWM fan headers?

After more searching Asus Z97I-Plus might have 3 PWM headers. The manual lists pin4 as 5V, but suggests there is an option in BIOS to switch from DC to PWM control.
