Hi. And happy CRISTMAS! Z-77 mobo is better with 3570k. New version is 4670k and Z-87.
So there is not avible gigabyte mobo? X-D3H is great choice. Z-77 or Z-87
3570k with Z-77 and 4670k with Z-87. Remember that you need good cpu cooler to OC
Turbo boost works with all mobos. Fan controll works trough bios if your mobo supports this PWM funcktion. Needs 4 cable fan connector. Or with program where you can adjust fan speeds.
Other option is buy fan controller. Cheap one is Zallman fan mate 2. Or 3.5 or 5.25 bay fan controller. And then you can adjust severl fams not just one. Also many new case do have fan controller pre istalled.
Maybe best choice if you have not OC before is Asus PRO. Expensive but good.
