I owned a Macbook Pro for a brief time&lt;p&gt;I was running Windows 7 in Bootcamp and I wanted to set up Gentoo Linux in a virtual machine for some Linux work I needed to do&lt;p&gt;I left the machine on my desk to compile a kernel. Basic wooden desk, nothing underneath or around it. No problems there&lt;p&gt;Roughly 5 minutes later, the system had reached what Speccy reported to be a scorching 117 degrees celsius! (242.6F)&lt;p&gt;I immediately shut it down and left it to cool off, then asked around on an IRC full of various flavours of IT people (programmers etc)&lt;p&gt;The horrifying answers I got were that this was INTENTIONAL and that &amp;quot;the system acts as a giant heat sink&amp;quot; which is why it didn&amp;#x27;t power off after crossing a threshold&lt;p&gt;As far as I understand it, running it under Bootcamp also disabled any kind of thermal throttling and forced the more power hungry &amp;quot;Radeon&amp;quot; graphics chip to be used, further adding to the problem</text></comment>
