BambooBook Heat Test
In this test* (Centigrade) the CPU temperature dropped from 62º to 60º in an 84 minute test.
In this test* (Fahrenheit) the CPU temperature varied from 140º to 153º in an 2 hour 35 minute test. However only the first 2 hours was the Macbook in the Bamboobook case. For the last 45 minutes the computer was used on my lap and then the CPU temperature increased to 153º. It ran slightly hotter outside the case. All of these reading are well within the operating specifications*.
*Test results may vary from time to time, however after 6 months of using the computer in the case we have never experienced any signs of overheating.
