The Official My Computer is too Hot to Work Thread

I had a kernel_task yesterday using 600% of the CPU. Slowed the MacBook Pro down to painful speed.

So after some rebooting, repairing disk permissions etc. etc. the answer came in propping the laptop a couple of inches above the desk for clear air flow, and sticking a fan next to it. Voila, the kernel_task disappeared and back to zippy fast working again.

Anyone else have hardware that gave up in the heat until it got better working conditions?

p.s. I don't know what a kernel_task is before you ask....

I'd be more worried about it using more than 100% of the processor. Good trick if you can do it.

I've worked in and designed data centres now for over 15 years. Servers and PC's over heating is more common than you think if airflow is not managed correctly. You are one of many suffering this week I'm sure. Keeps me in a job! :)

The heat has buckled BT's fibre this morning, broadband intermittent.

as [MENTION=28206]Rod Marsh[/MENTION] notes, its not uncommon problem. heat or how to manage it is the biggest constraint on compute performance. many processors now operate at reduced speed normal operations, only going to full throttle when needed, to keep temp down.
