This is great, except...
What if you are running this at 2000rpm and you are doing some very CPU intensive work? The fans will stay at 2000 rpm because it is a "forced" value instead of "auto" ... right?

I know this is a bit late to answer but I was surprised nobody mentioned Temperature Monitor Lite or SystemLoad from: http://www.bresink.de/products.html
The SystemLoad software allows you to put a user definable load on your CPU and the Temperature Monitor software (both free, btw) helps you monitor the temp of BOTH cores very easily. Many methods to monitor including the menu bar, dock icon, widget, etc... check out that website:

VERY cool and FREE products to grab there.

You can't just run from the image...you have to move to the Applications folder so that the script references are correct.
Dont' worry...I did the same thing.
thank you so much rokem and all others who contributed. i love apple so much so i was very dissapointed with them when i hyped up how cool my MBP was to my friends until they eventually said "wow that bitch gets HOT" 🙁 so this is an amazing fix! just hope it doesnt kill my fans!
this is the kind of thing that makes me want to get geeky with mac os x.
my temps are running around 40-45 Degrees C and even dips down into the high 30s. on of my friends here at school has a 17 MBP that has been randomly shutting down and i think it may have something to do with the heat its running at, maybe a faulty heatsink or bonding, but im definately goingto run this for her and see whats goin on, cus the apple store is givin her the run around and im fed up with them. (remember when they used to be friendly and not cocky?)
i have some questions tho.
i copied the text from the first pdf that was posted in this thread, but havent changed them back since i downloaded the smc. should i modify them at all at this point?
is it a good idea to put the fans back down to a slower speed eventually? when? and if i just run that script will it take over for the previous scripit i ran for the faster fan speed?
and one more: my cpu percentage has been fluctuating from about 4 % and spiking up to around 16% but usually staying at a steady 2.0 GHz which is the advertised speed of my processor, is this normal?
OH WAIT ONE MORE THING! i have the istat nano widget. although i have been using coreduotemp to monitor the heat, i would like for it to work in the istat nano, but the temperature reading is the only thing that wont show up for it. anyone else have that problem? any solution?

I wish I could make a script that'll run the default at night at a set time without entering password so I can sleep with quiet fans then reverts back to 3000rpm at like 7am. That'll be awesome
Why was the logic board replaced? I have a week 11 build as well

WARNING: This claim may NOT be accurate.
Ok I think I have a serious problem w/ these scripts. Here's the deal.
As I expressed earlier, the scripts DO work, but in terms of adjusting to CPU load, I believe it is broken, and here's why.
I was working on my bed w/ the 2k rpm running, but because I leave my mbp on overnight I decided to revert back to default rpms for the sake of habit. As soon as I loaded the default, the fan instantly sped up to at least 4k and back down to what the auto settings felt was suitable.
I found that to be a VERY scary experience because I wasn't even doing anything cpu intensive and the temp b4 i reverted back to default was at 74*C. So it seems as though the script is no good in conforming to various user loads since it runs at a constant fan rpm. Those who are running this at that low rpm probably has a chance of really blowing up their machines if the area is not well ventilated, running cpu intensive stuff, and not watching their temp.
With that said, i'll have to find a 100% cpu load temp I am comfortable with playing w/ the rpm script. While that is a viable option, the noise level could be higher than I like since it doesn't auto adjust. But i'll find out more.
In any case, if my assumptions above are correct, it would seem that the script is more of a temp fix than a permanent one. If the auto-adjust is to be implanted into the scripts, then it'll be awesome.
Am I high or the only one that's experienced this?

The other option other than running the default is to "ReBoot". The scripts are not permanent and revert back to automatic after the reboot, although I wish it was sometimes. But if you are running a very intensive app and your temp soars to where you feel uncomfortable then you can always execute it at that point for the duration and then either reboot or run the default speed script. As far as fan life I really cannot speak of how an MBP or MB will do but like others I have a Dell XPM Desktop that runs pretty much 24 hours a day and has for about 18 months of the 2 years I have had it. I have it on an UPS and use it as a Server running XP Pro SP2 with 1G of Ram. And my fans are definitly loud when they get a lot of processing going on but its liveable and I have not had a failure yet "Knock On Wood!". Hopefully the Macs will be just as endurable. For me when I am running a Game or Doing some Graphics and it pushes the temps to much for my taste then I will use the scripts until some GUI shows up that might allow for manual "Setpoints" to monitor and adjust the Fan Speeds.neom said:

The files ARE in my applications folder. Else I wouldn't have ask 😛matperk said:
Code:
THIS FOLDER NEEDS TO BE PUT IN THE APPLICATIONS FOLDER TO RUN.
Presets for Fan Speeds. Just open desired speed,
click run, and enter admin password.
The default file resets fans to a state
before any speed changes were made.
the smc programer has made some slight changes to the program. An algorithm that keeps the comp. running at desired temp and now it saves the changes after waking from sleep. i will be posting a new apple scripts latter today.
PLEASE NOTE: This will NOT work on anything with a g3 g4 or g5 processor in it. also these scripts were designed for mb's and mbp's.

also a 3" fan running at 2000rpm does many times more work than a .75" fan running at 6000rpm.

Why this can't be an option built into OS X is beyond me. Im sick of MB and MBP's that are way too hot.

Someone up above pointed out that Rokem's scripts set a FIXED value for fan RPM... they don't allow for the possibility that the fan might actually need to go faster if the CPU needs it.
Is it possible for the scripts to be modified to set a MINIMUM RPM value, while still allowing the fan to go faster if needed? In other words, don't set a fixed speed, set a minimum speed which is faster than the default minimum speed.

Same here about a month back. Besides getting a whine free MBP my casing is noticeable cooler and the temps never go higher than 64 celsius.ckoerner said:
It would go all the way to 74 before.
Maybe Apple changed the RPM setting on the new Logic Boards.
Did you experience a drop in temp after getting the new LB?
Rokem, just wanted to say that this works excellent in the Mac Pro
but even at the 2000 RPM it is very loud, can we make like a 1500 RPM one?
