Let me go read through that and hope that it enlightens me a bit more.🙂😱 Thanks!
That's kind of the approach I took. I am going to read-up a bit more and see what I can do to improve things. Thanks!

MBA SnowLeopard and Spinning wheel of death
Lately I have been witnessing a total unresponsive MBA sometimes.
The symptoms are all over the place:
1. Safari crashes while clicking on Inbox of Yahoo email after spinning for 20-30 secs.
2. Dock takes 3-4 seconds to show all icons when you drag the mouse pointer all the way down.
3. Some of the sites makes safari just keep spinning testing your patience, whereas it works fine when I try on my IBM laptop both connected wirelessly.
Not sure if it SL, Wireless connectivity or under volting. My suspicion is on MBA wireless connectivity and if that gets stuck, it hangs MBA.
Any one else experience this?

Quick question re coolbook.
So, I have a rev B. I can run all speeds on the lowest voltage. Is there any reason why it shouldn't just be run at the max mhz all the time since it's using the lowest voltage anyway? Is there less heat with a lower frequency even though the voltage is the same?

Sorry to sound like an idiot
but..
None of it is sticking to my brain.. Probably because it's 7:50 AM and I have had no sleep at all because I just read this whole thread.. when I open the app.. 800MHZ is not showing.. here are some screenshots:
and
I am also not sure I am doing this right, even though I can sort of see a dramatic decrease in the fans.
I have a Macbook 1.83 GHZ Intel core 2 Duo with 2 GB 667 MHZ DDR2 SDRAM
Please can someone who knows what settings for coolbook I should use for my macbook post them up?

Then I guess it doesn't help staying up all night, eh 😛
Use buttons.
"Clear" is your ultimate friend, use "Default" first - note what it populates the list with.
Then "Add" your own frequency steps carefully setting voltages.
When you work it yourself - you'll figure it out without burning midnight oil.
And there is no definite settings - coolbook is there to customize your own MB.
Though you can take somebody's settings as a base for your own experiments.
Yeah I need sleep.. But I am not going to until I get the damn fans to shut up.
Is there anything I can copy that comes close to my macbook settings?
I just don't get the whole volts and MHZ.. call me dumb if you wish.

You have a MacBook, this post is about MacBook Air... big difference.
Press Default, it'll populate the entire list and voltage settings. Select the Mhz and change the voltage. When you're done, press "Add" and it'll add it into the list. After you finished all of those, press "Save".

Yes with MB you'd have a bit different settings. yours looks like a couple generations old.
"Default" you use to see what are the factory settings, and then "Clear" and "Add" your own - working down from what's default for each step.
IIRC you need to use "Set" also at some stage (was tuning it ages ago🙄)

BTW MB (2.0Ghz, late 2006) was my first test rat with coolbook.
I remember it's fans as a bit more hysterical 😀
So I created few scripts for SMCFanControl.app, and I ran them manually (choosing from a scripts folder on the menubar)
try to look them up in this thread IIRC, query this: "-k F0Mx -w 2710" for example (this one should calm fan down to 2.5KRPM).
If you set it at ≈3-3.5K it should be barely noticeable.

Need help
I have a 1.8GHz MBA. I read the whole thread and changed my coolbook settings and upon restarting, the computer kept freezing and I would have to keep restarting it and quickly change my coolbook settings back to default before it froze again.
I only use my MBA for writing and email.
There were my settings: (Any advice? Was it bc the voltage was too low?)
Adapter:
1200MHz 0.9125 V
1400MHz 0.9250 V
1600MHz 0.9375 V
1800MHz 0.9500 V
Battery:
0800MHz 0.9000 V
1200MHz 0.9125 V
1400MHz 0.9250 V
1600MHz 0.9375 V
1800MHz 0.9500 V
Throttle: Medium Temp Limit: Off

If it's freezing, then your voltage is too low. You need to raise your voltage a bit. It's a trial by error type of technique. Not every CPU is built the same way even with the same methods and materials.
Undervolting more
Hi, i have recently bought a first gen 1,6ghz Macbook Air v1.1 , and have done all the things available to stabilize temperature and eliminate core shutdowns (coolbook, smcfancontrol, max fan rpm script). I am new to mac, and use rmclock in windows, i am accostumed to it, it lets me undervolt a lot. The question is this, is there a non standard way to undervolt more than 0.9v???, i think it may be possible with some program tweak to coolbook.
The thing is that Macbook Airs generate a lot of heat even at 600mhz and 0.9v, i think it should manage ok at 600mhz and 0.875 for example, and at least we should be able to try, i dont think the cpu is hardware capped at 0.9v, please correct me if i am wrong.

Hey guys sorry to interrupt but can I ask a question about Coolbook on the Unibody Macbook Pro 2.53 late 08?
If so, the question is that the settings I am using won't apply themselves even after I save and restart. My adapter settings range from 1596 MHz at 1.0000V to 2527 MHz at 1.0750V, but even when I do save and restart the status info always alternates between 1596 and 2527 MHz at 1.1750V!
Am I doing something wrong?
I would appreciate the help...

I had a similar problem on my MBA recently after upgrading coolbook to the latest version. The only way to solve it was an unistall, a reboot, a re-install and again a reboot. Works perfectly again.

Hi all, I'm new to the mac's world.. I've a macbook air 13 with latest 10.6.6 mac os.. I noticed that cpu temp is a bit more hight respect other laptops that i owned.. and I decided to install software like coolbook to manage to undervolt and underclock the cpu..
I've some questions:
1: is this software really necessary? doesn't the os manage dynamic cpu frequency scaling itself?
2: once installed coolbook and saved settings, have it to be running during normal use or it is enough to save settings?
3: coolbook shows on the menubar freq and temp of cpu and I like it. But I would like to hide the "running" icon in the dock and I don't know how to do it! is there some way to hide coolbook icon? or alternatively is there another app that shows freq and temp of cpu in the menubar?
thank you.. again I'm sorry if this questions are stupid.. I'm new here 🙂

Very old thread............. Are you using a newer 2010 13" macbook air. If so the information here may not be applicable.
I'm sorry this is my second day as mac user.. my dad just gave me his old macbook.. I'm a little confused 😕
this is how it is reported in the system info:
Nome modello: MacBook Air
Identificatore modello: MacBookAir2,1
Nome processore: Intel Core 2 Duo
Velocità processore: 2,13 GHz
Numero di processori: 1
Numero totale di nuclei: 2
Cache L2: 6 MB
Memoria: 2 GB
Velocità bus: 1,07 GHz
Versione Boot ROM: MBA21.0075.B03
Version SMC (sistema): 1.34f8
it is in italian but it is easy to understand..
I don't know if it is a newer 2010 model..

1: Of course it's not necessary. But the settings of the OS are way too safe, not at all optimal in many peoples mind.
2: It doesn't have to be running. Just open the app and see that the active checkbox is on.
3: Why do you need to see the freq/temp 24/7? For CoolBook, it's not possible to see it in the menubar but not in the dock. Take a look at the apps from http://www.islayer.com/apps/
how many people still use this? I'm trying it out on my new 13" air. I'd be interested in other's opinions on this.

I'm still using it on my '06 2.0 WMB - a lifesaver, and a sanity restorer 😕
But I'm yet to see the need on my '10 2.13 UMBA under the heaviest of loads 😎
