Okay to disable right fan and have left fan running at full speed?

[flarn2006]

I've been having a problem with my right fan being too noisy (I mean like a grinding noise), and right now I have the fans set up like this:

smc -k 'FS! ' -w 0003 #Manual speed mode for both fans
smc -k 'F0Tg' -w 60e0 #Left fan set at 6200 rpm
smc -k 'F1Tg' -w 0000 #Right fan set at 0 rpm (disabled)

Is this okay? If it gets too hot, the system will do an emergency shutoff, right? (Then I can reset the SMC before starting it up again.) Right now, the CPU temperature is hovering around 60-70˚C after having it like that for a few minutes. And what about setting the left fan to automatic control? Would that be okay? Also, what about increasing the speed of the left fan above the factory-set maximum of 6200 rpm? Like maybe 7200?

Why don't you simply buy a new right fan?

Well, that's the plan. I have AppleCare coverage and I'm going to take it in, but this is just a temporary solution.

No this is not okay. Take it in as soon as possible.

Okay, will do. Thanks.

Thanks for that info. I've been looking for a way to keep my fan speeds down for a couple years as I too have the grinding problem with my MBP fans. Rather than setting a manual fan speed, I let smc handle the fanspeed but limit it from going above 3k rpm with help from this http://hints.macworld.com/article.php?story=20110704054835249

Here's what I use:

type: "su" and enter root pass
type: "cd /usr/local/sbin"
type: "pico smcFanReset" and paste the following

#!/bin/sh
#
# Read CPU0 temperature via smc tool and convert in decimal value
#
TEMP=$((0x$(/usr/local/sbin/smc -k TC0D -r|awk '{print $4}')))
#
# Depending on the actual temperature value adjust the maximum fan speed.
#
if [ $TEMP -le 99 ]
then
/usr/local/sbin/smc -k F0Mx -w $(python -c 'print hex(3000 << 2)[2:]')
/usr/local/sbin/smc -k F1Mx -w $(python -c 'print hex(3000 << 2)[2:]')

fi
# END OF SCRIPT

press ctrl+x then Y to save.
type: "chmod +x smcFanReset" to make it an executable

grab smc from smcFanControl and type
type: "cp /Applications/smcFanControl.app/Contents/Resources/smc /usr/local/sbin"

For anyone wondering how to set specific fan speeds with the OP code, take the desired fan speed and multiply it by four then convert to hex. For ex: 3000*4 = 12000 converted to hex = 2ee0

To fix the fan grinding noise without having to buy a $30 fan you can simply grease it up using this guide(except, don't use wd-40, use real grease such as 3-in1): http://nofilmschool.com/2009/02/how-to-fix-a-noisy-macbook-pro-fan/
