Anyone knows how I can turn off the right fan, when i just use the intel graphics. It's because I could increase the battery life.

Another question.
Which program can I use to reduce the fans speed. I think that the macbook don't need 2000rpm at all time. 2000rpm make some noise.
I have the fan control and I specified base speed with 1200rpm but it is always at 2000 (right and left fan)

Don't mess with your fans. Disabling a fan (even if you could) to save battery life is foolish. You could fry your computer. 2000 rpm is the minimum fan speed. What you think your MBP needs and what it actually needs are two different things. Your MBP knows how to regulate fan speed as necessary to keep from overheating.

The fan control setting is to force a minimum speed, not a maximum speed.

This is what gets people in trouble lol. Seriously, even if you were able to change the fan speed, what would you be saving, 5 minutes of battery life? To me that wouldnt be worth frying my computer.
 
With no fan control software, my MBP is running with the fans at 1991 rpm each. Is this normal?
 
Short: You cant

Shorter: DON'T

As for that 1991 or what ever RPM. Fan speeds are imprecise and will fluctuate a bit around the target. Its common and no big deal.
