Title of the thread says it all really...mid 2009 MBP 15" 2.8 Ghz
Your question is very vague. My first response:
...because you didn't set it to 2000 rpm.
A more reasoned response, and what I think you're asking:
Because a "minimum" is just that. Your computer thinks the fans need to run at a higher speed.
Mmmm OK I see why you'd get confused I wasn't very clear.
My normal minimum is 2000 RPM. With SMCFC running, the minimum I can set is 4651, which isn't the actual minimum, even when not on charge and idling with just Finder running (i.e. shouldn't be hot).
I'm wondering if there is a fix for this, so I don't have to shut down the computer and restart to disable smcfc. Thanks
Actually, even with Finder running, it can take 100% CPU if theres a problem. What does your Activity Monitor show for processes and %CPU?
CPU's idling around 90% so thats fine and loads of free memory, no leaks. The temperature is always around 38oC as well so its not hot. My point is that I can't set it to below 4651 in the settings--even if its running at 10 or 90 degrees. There is a software limiter below 4651 and I don't know why. Slightly older or different machines don't have this. Interestingly, when I first installed smcfc it let me ramp up to 9000 rpm (well above 6200 rpm normal) and I had to shut it down because of a grinding noise. It also let me down to 2000 rpm. But after the shut down I arrived at where I am now: 4651-6200 (the normal limit) rpm. I had FanControl--another software fan controller on the machine a few months prior but uninstalled all traces of it. I've tried reinstalling smcfc, but nothing gives.
Hmm, strange. I assume you're running the latest version of SMCFC?
Well, if my MBP had that high of CPU usage, them would be in the 50s to maybe 60s and my fan would be running in the 4,000s, but since your temp is that low, it must not matter.
Have you installed another fan control program and just forgot about it?
I mean it is idling at 90% and being used at 10% so its very low usage.
I am 100% sure theres nothing else there. What file do these apps edit?
Could perhaps hunt around for a clean one on the web/my mates MBP...
