How many chassis fans can the mobo support?

on the motherboard their is one chase fan, one sys fan, one cpu fan but you can use your power supply to hook up more fan download software to monitor the other fan speed on control them. I got watercooler for cpu 240, push and pull air flow, two 120 in front .and 120 in the rear, one of 120 pull air and the other push out, the one in the rear pull air in, and the 240 water cooler pull air into case. temp 20 and no higher then 45 on a full load.

How well does It do when overclocking?

I have not overclocked it, I am running the AMD FX9590, with an ssd, so I never really needed any more speed. But I can tell you this. This board has been the best gaming board I have ever owned. I`ve been building systems since 1990. It has been rock solid, not one single incident. That being said.....I totally recommend this board.
