Selvom jeg lukkede programmerne ned så brugte den systemressourcer der var helt abnorme på ca. 80% og den var frygtelig langsom og hang i programmerne. Jeg har surfet lidt og fundet programmet coolbook – se www.coolbook.se da problemet åbenbart – hvad jeg kunne læse mig til – er at computeren lukkede en af de to CPU’er ned ved kraftig belastning og når den blev lidt varm, hvilket bl.a. sker når der er tilstluttet ekstraskærm, mus m.v.. Jeg har nu efter nogle anbefalinger leget lidt med programmet og det ser ud til at virke – se evt. mere på Plasmablog [...] [...] Langsom MacBook Air Jeg har haft problemer med at min MacBook Air blev langsom sidst på eftermiddagen.

I live in humid state as well which didnt help anything. I have since installed Coolbook and SmcFanControl and my machine is running 'much' better. The CPU temp is much lower than usual. The fan speed is still alot higher but thats because I have SmcFanControl running as well. Go MBA!! I do love the machine even though it needs help like this at times!

They sent it to a repair station in Texas, and they replaced the motherboard and installed a cooling upgrade, all for free. It now works much better, and I've not had a core shutdown since.

I turned of coolbook as apple recommended. I tested my mba for hours. With external temperature 30 C, 2 youtubes, google earth, itunes and activity monitor the cpu temp is reaching never more than 70 C. With just itunes, wifi on, and 1 window of safari open, the temp never drops 53 C and the fan spins at 6155-6204 rpm. There is no core shutdown until now. But......there is one more thing..... In high temperatures and when many apps are open, or more correctly before the cpu shows 52-55 there is a slight slow down in the laptops performance (not freezing, i can still work normally). Reactions like that reminds the performance of my mba (sata, 1,6), before i use cool book and when i had 1 core shut down. With cool book there was no slow down at all, but the temp was very high always (60-65 C), and most of the time it was impossible to leave the mba in bear legs, and it was so hot that i could not touch it. Anyway i do not know if the issue is fix for sure by apple with the patch...... so…. i downloaded the patch yesterday 28 Aug 2008. I turned of coolbook as apple recommended.

The support notes warns third party apps that alter the voltage or characteristics of the CPU are incompatible with the patch and that they should be removed before the update is applied. Although not mentioned by name, this warning is an obvious reference to Coolbook; a third party app that I covered in an earlier post that lowers the voltage fed to the CPU. I have been running a newly patched MacBook Air for a few hours now. During that time I have had three flash videos running simultaneously along with Activity Monitor. I have yet to see a CPU core shutdown leading me to believe, that after a six month wait, the Apple update resolves this issue once and for all.

And i restarted it. In the documentation of coolbook says that setting temperature level will cause (maybe) core shut down, as i understand. I do not know. I ll try and ill let you know. thanks anyway look whats is happening. ….yesterday i left the mba raise in tests until it reachead 100 C. it could not show more than 100 C, it was saying 0 C!!!! the laptod shut down but no kernel panic occured.

A guy from another forum set 65 degrees maximum on his 2.2 ghz MacBook Pro and it works! So you can avoid core shutdowns and lower the cpu temperature considerably (which is good for the processor) while you do lose some of it's performance... If at 65 the performance is way too low then, I'm guessing, setting a higher one should improve things... I'll get back when I'm done testing myself... And maybe plasma or someone with more experience will give us more guidelines... Maybe his or her temperature setting? :P @ivan

My 2cod mba assembled April and it suffers from core shut down, but i still can use it with no big problems. (just some slow down in the trachpad). I purchased coolbook yesterday and used the rates mentioned in the top. no more core shutdowns. The highest temperature i saw in adapter mode is 81 C while verifying permissions. Also it reached 76 c with google earth, 3 windows in safari, quick time playing, xtube and youtube streaming, monitor activity and itunes at the same tines for about 6 minutes. In battery mode, since external temperature in Greece Eu never drops 32 C, i used it for 3 h 15 min with wifi on, word on, itunes on at the same time, while i was working. Amazing....... coolbook works. Guys thanks for the useful advises. My first mba assembled January and it suffered from core shut downs.After a month it was showing colored lines in the display.

After that try using plasma's 8 CoolBook settings (5 for adapter/3 for battery; listed above) and you should have no more core shut down... at least that happened in my case (and I ran anemona for almost 20 minutes), even though the cores were really hot - 80+ Celsius, but at least nu shut down... I'm curios how hot do plasma's cores get after 20 minutes of anemona... you can get anemona from here, for example: http://mac.softpedia.com/get/Screensavers/Flow-Screensaver.shtml Well, try installing the anemona screensaver… and test it with the default settings (no CoolBook, that is)… anemona will surely shut down your core in 2-3 minutes at the most…

And a core dropped out without ever getting much above that (during a Time Capsule backup). So I'm not entirely sure what tweaking with the values is going to gain me.
