Room Temperature App Free Program Recorded

Testing by Macworld Lab found that the switch from the Core Duo processor to Intels next-generation Core 2 Duo offering slightly reduced the 2.16GHz MacBook Pros persistent fever.

However, the 2.33GHz model got just as hot as its Core Duo counterparts.

Still, considering the Core 2 Duos superior speed and power, these results show improvement in the MacBook Pros system-cooling technology.

The 15-inch 2.33GHz MacBook Pro Core 2 Duo reached 117.9 degrees (Fahrenheit) above the keyboard and 116.6 degrees in the area near the battery.

That compares to high temperatures of 116.9 and 116.1 degrees, respectively, for the 15-inch 2.16GHz MacBook Pro Core Duo.

By way of comparison, a 2GHz MacBook with a Core Duo processor showed peak temperatures of 105.1 and 101.8 degrees, while a 15-inch 1.67GHz PowerBook G4 heated up to 112.5 and 112.3 degrees.).

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 while converting MP3 files in iTunes.

Internal temperatures were recorded using the CoreDuoTemp application; because the program does not run on PowerPC-based Macs, we could not use CoreDuo Temp to record the internal temperature of the PowerBook G4.MACWORLD LAB TESTING BY BRIAN CHEN.

The free program recorded high internal temperatures of 178 and 174 degrees for the 2.33GHz and 2.16GHz Core 2 Duo models, respectively.

The 2.16GHz MacBook Pro Core Duo reached 176 degrees, while the 2GHz black MacBook peaked at 167.

We excluded the PowerBook G4 from this test since its incompatible with CoreDuoTemp.) All testing took place in a cubicle with a room temperature of roughly 74 degrees; each machine held 1GB of RAM and ran MP3 conversions on iTunes for 40 minutes.

In fact, since this most recent round of MacBook Pro updates featured no major changes to the inside of the machine (save for the chip swap), it would be fair to say that Intel is taking the lead role in keeping the MacBook Pros temperatures steady.

An Apple representative told us that both the previous and latest lines of MacBook Pros are noticeably cooler because of firmware updates released in May and June that adjusted fan speeds.

Its reasonable to assume that future firmware updates could produce similar results for the latest MacBook Pro models.) There still isnt a tried-and-true method of temperature testing, so we welcome input from MacBook Pro users on these results.

What are you doing with your MacBook Pros when they start to heat up After some experimentation (with Quake 4, Adobe Photoshop CS2 Automator actions and DVD playback), iTunes MP3 conversion heated up the MacBook Pros for us the most.

Since these tests were all run on machines with screens no larger than 15 inches, were eagerly awaiting the arrival of the 17-inch 2.33GHz MacBook Pro Core 2 Duo.
