[Kissayksisarvinen]

i have gigabyte ga-z97p-d3. i have 2 fans and i can connect them by 3-pin and i cant find another one in my board

most of the fan plugs in motherboards use 4 since they support PWM speed management for fan speeds.
they work fine with 3 pin fans too. (one of the pins just is left empty)

the manual lists 4 fan positions.
CPU
and 3 system fans.
as shown in page 4 of manual

I have highlighted all the fan connector ports available on your motherboard; (after much size tampering)

3-pin fans will also fit in 4-pin connectors, plastic brackets will allow you to insert the 3-pin connector only one way.

If you want to connect more fans either use a molex to 3-pin fan adapter (no speed control -> fans always 100% -> cheapest option) or buy a fan controller

If you look at the board so the CPU socket is at top centre, your 4-pin SYS_FAN 1 & 2 headers are just below it and a bit left. Your 3-pin SYS_FAN 3 header is half way down the right hand side next to the front USB header.

Your CPU fan header is right on the top line above the top gold heat sink.
