Over on the mighty MacFixIt, reader “Martin V.” wrote in to desribe an ongoing issue wherein his new MacBook Air notebook began to experience a “kernel_task” process that caused his system to run abnormally hot.
“A few months ago I bought a MacBookAir1,1 (standard hard disk, no solid state) which was then hugely reduced in price (€999). Lately it has been nearly impossible to watch youtube video’s (for instance). If I do the machine gets really hot and slows down dramatically. A process called ‘kernel_task’ uses almost all resources. Just do a search on “macbook air” and “kernel_task” and you’ll see this is a widely spread problem”
Over on the Apple Discussion Boards, a large number of users appear to be encountering the same issue with the following solutions being offered:
“it seems to be temperature issue, i.e. the system tries with the kernel task to avoid an overheating of the cpu/gpu.
those guys here (Plasma Design) recommend a cpu undervolting to reduce this heating. they use CoolBook
you can get it for $10. i just installed it and hope that it helps.”
In addition to the Apple Discussions Board back and forth on this, you can also find a full MacRumors forum thread as to how to use CoolBook to best deal with the overheating issue.
