So, I downloaded and paid for a Coolbook license last night. I then followed a couple of peoples post and had my settings all set correctly, but my voltages wouldn't change. Nothing worked, so I figured, maybe I have to click on the "Coolbook Active" box and then restart my MBA, so I did just that. Restarted my MBA, checked Coolbook and nothing had change. Voltages were the same, and strangely, my MBA was running HOTTER than before. My temps were at 135°F - 165+°F depending on what I was doing when Coolbook was active. This concerned me since my MBA normally stays at temps of 100°F to 130°F without Coolbook (right now without Coolbook, my MBA is at 99°F).

Am I doing something wrong? Can someone tell me why Coolbook is making my MBA run hotter than normal and why it's not letting me change the voltages? Also, when I click on my frequencies to see which ones I can change, the drop-down box will open, but there's only two frequencies: 1596MHz, and 1862MHz. However, in addition to those frequencies, in my list of default frequencies on the left, 798MHz is in the list, but when I go to search for it in the frequencies drop-down box, it's not there. I can only find 798MHz when I click the little box that says B/2. Is that normal?

Thanks. :)

Bump:D Just helping....

I am surprised you are running cool book on a 1.86 . I have read the ultimate both 11 and 13 run cool book to bring them down to the base speed spec of 1.4 and 1.86. More for battery life then heat.

My 1.86 has to be the coolest laptop I have ever owned. Unless you are using Skype, lol....

Good luck:p
 
I don't know why people bother with this. My MBA 13" Ultimate is the coolest laptop (both temperature and looks :D ) that I've ever used except for the 11" MBA. If you ever used the first Intel based 15" MBP, this thing is nirvana.

To be completely honest out of both of you, I mostly wanted to put this program to the test to see if it actually worked and could make my battery last longer while also making my MBA run cooler.

Yes, my 13" runs amazingly cool and has long battery life, but why not try and extend that battery life, or even try to make it be a little cooler. :)

It's only $10 lol.

But, so far, I haven't been able to get it to work.
 
I understood doing this on the original MBA which was terribly flawed with an overheated Merom CPU and Intel's God-awful IGP. However, it was senseless to do it with the Nvidia-based MBA in October 2008 and June 2009. And it's downright pathetic to tamper with an October 2010 MBA, as it's shear perfection as is. It doesn't need the gimmicks to make it something else, as it's completely capable running stock.

I wouldn't want to alter perfection.

In my opinion, nothing is perfect and nothing will ever be perfect. There is always room for improvement, and even though the current generation of MBA's are awesome and run cool and get great battery life, why not try to make that even better? Why not try to make it run cooler and last longer when other people that have used it on their current-gen MBA's have said it works great and it does no harm to MBA's?

That's just my opinion, though. :)

Not half as pathetic as this post.

Seriously? Perfection? I have a MBA and love it but it's far from perfect.
 
Bump. I still haven't received any info on this. Can someone please chime in with their allowed voltages/frequencies on their 13" MBA?
 
My settings are below, which have been stable with my 13"/4GB/256GB SSD.

High-performance when on AC at lowest voltages that are stable:

Longest-life lowest-voltage/clock speed when on battery:

For some reason, my voltages aren't changing when I click on "Set" or "Add". Any suggestions?
 
On my MBA 13 ultimate I'm able to run all frequencies at the lowest voltage of .925 and it's still stable. Contrary to other posters above, I've gotten up to 10C cooler with coolbook and now my 13 is quieter than the 11 stock. That's even with flash web content.

uh uh not really tampering with coolbook, but extending the cpu life by making it run cooler and as an added effect -- more battery?

I'm getting at least 1 more hour of battery a charge with coolbook installed at 0.875v (11" ultimate). No complaints here :)
 
Hmm. I can change the voltages, it's just that the voltages aren't actually changing when I click "Set". Nothing changes. The voltages stay the same.
 
i found that clicking "throttling active" then "coolbook active"

and then "coolbook active" and "throttling active" to re-enable them followed by a reboot works everytime for me

I would uninstall, reboot and then reinstall. And then write the author, when I've had problems in the past I've had him responsive and helpful.

Still nothing. I've emailed the developer, but I haven't received an email back yet. How long did it take for him to email you back?
 
Stupid question, but did you click 'Save" after clicking add and set? You have to click Save otherwise nothing will work. It will ask you to run some small test when you click save so do that to make sure the machine is stable at the lower voltages.

I use Coolbook at 1.86 13" and it's working great. Takes much longer for fans to ramp up now when playing games or using Skype for example (lol at the 'perfection' comment, just run any Valve game and watch your perfection deafen you with the 6000RPM fan noise within first minute of use)

I've done both, but I will try it again later today. Hopefully it'll work this time.

Wow, i have the EXACT SAME ISSUE that i have! Your Coolbook is behaving exactly like mine! Doesn't do anything when i click set/save, and it's WAY hotter. I have a MBA Mid 2009.
I emailed the dev too.
Have you got a response?
