![]() ![]() It’s reasonable to assume that future firmware updates could produce similar results for the latest MacBook Pro models. ![]() (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. When I run Apple Diagnostic, I get PPF004 / PPF003 There may be an issue with the fan. TGPro and SMC fan control both report that fan is at 0 RPM (it is not, it is at a very high RPM). We are proud to be the first app to offer this functionality for the latest Mac models. TG Pro is a unique tool that lets you monitor CPU/GPU temperatures and provides fan control on your Mac. Heat Transfer that is being published as the NASA Special Publication. Were excited to share the latest TG Pro 2.82 release. Sensors are not reporting high temperature. This is the third and final volume of the series Thermal Radiation. 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 Pro’s temperatures steady. I used apps such as TG Pro, determines that fan and sensors are working properly. That the 2.16GHz MacBook Pro Core 2 Duo produced cooler results than a Core Duo laptop with the same clock speed indicates that Intel is making strides with producing more powerful chips that use less energy. (We excluded the PowerBook G4 from this test since it’s 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. The 2.16GHz MacBook Pro Core Duo reached 176 degrees, while the 2GHz black MacBook peaked at 167. The free program recorded high internal temperatures of 178 and 174 degrees for the 2.33GHz and 2.16GHz Core 2 Duo models, respectively. We ranĬoreDuoTemp, an application that measures internal temperatures of Intel-based Macs. Of course, it’s not just what’s outside that counts.
