You don't need to do anything with fan settings. Your Mac will manage the fans as it needs. It monitors temperatures and adjusts the fans when it needs to.

Not always, on some Macs the SMC simply doesn't work. If when your gaming or doing intensive tasks you can see the CPU getting around 90C (use iStat to check) and the fans still havn't come on, then install Fan Control 1.2 and set the upper to 81C and the lower threshold to 60C and the base speed to 2000rpm
