Hi, I have the GIGABYTE GA-Z77X-UD5H-WB LGA 1155 Intel Z77 Rev. 1.0.
The mobo has 4 system fan headers. The diagram in the manual says the following for those headers:
Fan 1
Fan 2 / 3
Fan 4
The documentation doesn't explain the differences between these headers. My questions are:
1) Which headers are PWM capable?
2) I have 4 PWM case fans I'd like to install and use the PWM feature - if only headers 2 and 3 are PWM, do I need a splitter or hub? Can I run more than one fan off the header?
I have the Arctic F12 fans. Thanks for the help!
