A workaround for the MacBook 6200 rpm issue
Authored by: theosib on Jul 07, '11 08:31:41AM

That is incorrect. Lobotomo's FanControl allows you to set a slope and offset that dictates minimum fan speed as a function of temperature. It basically does what the built-in system is supposed to do, which is to adjust fan speed as temperature changes. Also note that it sets MINIMUM fan speed, so if the built-in mechanism disagrees and wants the RPM higher, it will be higher. I don't like smcFanControl, because it only sets a constant, so it's loud all the time. With Lobotomo's FanControl, it's more intelligent. I set mine to adjust the high end. At the low end, my 2011 MBP was fine, but when the CPU temperature would hit 90C, fans were not at maximum, and the machine got really hot, so I have it go all the way up to 6000 when I'm over 85C.

I know that. The point is that I want it more silent. Fan Control, like smcFanControl adjusting the minimum fan speed can only make it louder.

Anyway, I actually put my hands on the Fan Control source code and modified it. I used to be a developer ages ago, so I can still do some little things. I changed few parameters and added the lines to write the SMC max rpm as well. Now the fan speed goes proportionally with the temperature, in a much more dynamic way than the script. I know this is not a solution, but it does the job I wanted to achieve. Actually now it does what I tought those tools were supposed to do since the beginning. It shouldn't be dangerous because I've set the high threshold to 80 C. After that (but one can choose a lower temperature value) it goes to 6200 rpm.

Still, my only hope is the new thermal paste. Something is really heating too fast.
