Elsewhere on Macworld.com, we’ve published the table of our MacBook Air temperature testing in Fahrenheit. But past temperature testing has shown that some readers appreciate seeing the results in Celsius, too. So here’s our table, converted for your convenience.
MacBook Air Temperature Tests (Celsius)
||External Temperature Near Battery
||External Temperature Above Keyboard
||Internal Temperature (Main Heatsink1)
| MacBook Air/1.6GHz Core 2 Duo
| MacBook/2GHz Core 2 Duo
| 15-inch MacBook Pro/2.6GHz Core 2 Duo
| 17-inch MacBook Pro/2.4GHz Core 2 Duo
| 15-inch PowerBook G4/1.67GHz
Best results in red.
All results are in Celsius. To measure external temperatures, we used an infrared thermometer to get readings on the bar above the F-keys and the area surrounding the battery on each laptop. Temperatures were measured after 20 minutes of running six Apple QuickTime trailers and converting a video with iSquint simultaneously. Internal temperature was recorded using Temperature Monitor. We did not run the test on the PowerBook as Temperature Monitor does not produce comparable results for PowerPC- and Intel-based systems.—MACWORLD LAB TESTING BY BRIAN CHEN
