my mbp 40f cooler!

I'm much cooler than I was before the swap...Wait, that sounded wrong. My MBP runs about 20 deg cooler.

Nice. Could be reapplied thermal paste or a change in rpm settings. Who knows, and who really cares. Just as long as it's cooler.
 
Using Rokem's program on my MBP, with 2500 RPM, I can actually get my MBP to run BELOW 100 F at idle/low usage. The bottom of the computer is just minimally warm, and the top area above the 2,3,4 keys is actually cold to the touch. :)

I am so pleased with this fan thing! I have fallen in love with my MBP all over again.....now if I could only get the grinding fan noise to go away!!!
 
Try 3000RPM. For me, 4000rpm was actually quieter then 3500rpm. More air noise, less motor noise.

But my fan (the one on the right) is going bad.

It makes sort of a grinding noise when running, like there is a cord hitting the blades or something.

I need to take it to apple, but I can't be without my computer for a long period of time.
 
Open the case and haev a peek. It's very easy to do and apple would never know you were in there. The fans are visible once its open.

I'm tempted. But I would absolutely die if I screwed something up.

I think I am going to wait until christmas break and send it in for the myriad of problems it seems to be having.

I have:
Fan Noise
Misaligned Keys on Keyboard
Warped Lid (really bad)
Heat issues (maybe I can get that fabled logic board replacement)
LCD Buzz
CPU Buzz

Come to think of it, I have like all the bad problems the MBP's were having.

BUT, I still adore mine!
 
HEH ok. If you change your mind, opening the lid is easy...there is one very easy cable that connects the keyboard to the logic board. Once that's off, the thing just lifts off.
 
I have a rather exceptional request.

I did the thermal paste mod, and reapplied the thermal compund, since then my MBP has been really cool. I usually can't get it past 48 C, in idle it runs at 44 to 46. As the heat is now being transfered to the sensors much better, the fans do kick in too fast, when I load a game. After the SMC upgrade Apple set the threshold values way down, to prevent MBPs overheating.

My MBP is now nowhere near a critical temperature when the fans run at full speed. It actually rather have a 5 degrees warmer MBP. And just to mention it, I did not forget to connect the temp. sensors back, as the fans run normally when the MBP isn't under load.

When I start a game and the temperature reaches 50 C or maybe gets even higher the fans go all the way up to full speed. The MBP remains cool, but playing a game with such high amount of noise isn't a plessure.

So I'd rather have my fans to spin less. I think they would still take away enough heat, they do not need to keep my MBP at such low temperatures. It can handle more.

How do you think I should edit the fans settings?


I'd also like to see settings from a MBP prior to the SMC update.
 
This solution is fine if you prefer to manually control your fan speed as you see fit. But personally, I play full screen games that heat up the laptop quite a bit...I want the fan to go to 6000rpm when it needs to, and then calm down a bit when it doesn't (as 6000rpm can be quite annoying after a while). There is another solution that goes along the same lines, but instead of setting the fan at a defined speed, it increases the minimum speed. This allows it to bump up the fan when necessary, but never allows the fan to drop below the given value.

Use your terminal to locate the folder that contains smc, then use the following commands:

./smc -k F0Mn -w 2ee0
./smc -k F1Mn -w 2ee0

The "2ee0" sets it at 3000 rpm. Someone posted at the end of page 7 in this thread the actual values for the different speeds. I think this is a much more suitable solution for some people.
 
This works!

I followed your instructions on my 2.17GHz MPB, which was always hot, but since I upgraded to 2GB of RAM was just waaaay too toasty.

It worked. I am running 40-50 degrees cooler, I don't hear the fans at all, and if there's a change in battery life I wouldn't know because I am almost always plugged in.

Thanks!!!:D
 
I must be doing something wrong. I used the XML code in post #71 and modified both extensions. The first time it seemed to work. But then I suspended my computer and it appeared to go back to it's previous (very hot) state. (I'm not quite sure how the XML code gets rewritten.

So, I did it again and restarted. This time it doesn't appear to be working. Using TemperatureMonitor, my CPU shows 170.6 F. My hard disk is 114.8.

What am I doing wrong? By the way, I couldn't find the scripts. Where are these currently available?

Thanks much.
 
I'm using CoreDuoTemp to check the temps on my MacBook. Its been running for 3 hours now. Full brightness (power is plugged in), wifi on, mail/safari open, widgets open, iTunes playing. CPU is running at 2.0GHz, 12% CPU usage, and temps at 80ºF. Is this good or bad? I've seen it run as high as 115ºF during just regular usage. Using MacBook RSS Stress Test, the temps go as high as 180ºF.
Basically, it feels as though my MB runs cool under normal conditions, just wondering if I should bother trying this trick, thats all.
 
Look in this thread...

...for the most recent link from Lincoln Ramsay to "fanspeed.dmg". It's all self-contained, allows you to just run a command line tool and enter the RPM's in numerical values instead of hex and even hooks into SleepWatcher if you have it installed so it will run the script when your Mac wakes up from a nap!

Using Hardware Monitor to check my fan speeds and CPU Core temps both before and after changing my minimum fan speed from the default of 1000 RPM to 3500 RPM on my 2.0 GHz MBP, my CPU Core temps at Idle dropped from 48c to 37c.

To change my fan speed with Lincoln's app once it's installed, I just launch the command line tool included, enter the new value and hit enter and that's it. No digging for files and manually editing stuff!
 
I installed SleepWatcher, restarted. Then installed Fanspeed.dmg from the link, restarted. I can't seem to change the fan speed using the script included, and my temps are a lot higher at idle now. They were 81ºF and now 126ºF.
This is what is says in terminal when I run the change_speed.command:
Please enter a speed between 1000 and 6000 (inclusive)
3500
I might need your password to continue...
Password:
Adjusting fan speed (3500 - hex 36b0)
Error: SMCWriteKey() = e00002bc
logout
[Process completed]

Any ideas on what happened? Is there a way for me to see what the current speed of my fan(s) are?

Now this is what we need. A minimum setting that is auto, rather than a fixed setting that is forced. Anyone wanna make this work with Rokem's scripts? And then... anyone want to make it so it works on startup? :) That would be ideal.
 
I suspect the next revision will allow us to set a maximum temperature...or change the temperature fan threshold?
 
Rokem,

Would you mind posting the source in your current version of SMC (SMC 0.02). I'd like to see how you are doing your polling, and if possible, add it to a GUI.

Thanks

I'm running 3500 RPM and have experienced a noticeable difference in the temp of my 17" MBP. Unfortunately when I run CoreDuoTemp, the temp reads 72 deg. F regardless of how hot my MBP actually feels. This obviously isn't right...any reason that the proper temp is not being read?

The latest version of ministat2 v1.86 has just solved this problem.

It sounds like a bearing has gone out. That'll require fan replacement. Sorry, but it's something they will likely send in the laptop for.
 
Someone tell me if this is healthy:

Under maxiumum use, my processor reaches 82-83 degrees celcius with my fan a little over 6100 rpm. At low use, it stays at about 54-56 degrees celcius with the fan at about 1470 rpm.

Can anyone tell me which lines of code in Rokem's .plists (AppleBlower/Applefan) I would need to edit to make my fans run just a little bit faster? Or are these temperatures okay?

That's pretty hot. I think 40-60c is the ideal range for the cpu.
 
Okay, I figured out how to download the scripts.

I 3000rpm.app script. I can hear that the fan is on. However, I am seeing no change in the temperature. None!

According to Hardware Monitor:

CPU Core 1 is 183.2F
CPY Core 2 is 179.6F
Both Fans 1 & 2 are running at 0 RPM

The last items is particularly strange since I can hear the fans. Occasionally, it will run at 143 rpms, but just for a second.

What am I doing wrong?

Wow...I don't know what type of system you're running, but on my MBP I would shut it off if I saw those numbers. But you say that you can hear the fan, but the fans are running at 0 rpm? Are you using PPC or Intel, and are you running 10.4.8?
