Hi, my late 2008 15" MBP 2.8Ghz typically shows a CPU temp above 100 degrees Celsius ~ 216 F when using Handbrake. What is considered a normal operating temperature range?


Also Activity Monitor show that Handbrake is using more than 100% of the CPU how is this possible? What does it mean? How can you use more than 100% of the CPU? Can someone explain this?

Thanks

Most probably you have a Core 2 Duo CPU in your Mac, which has two logical cores, which Activity Monitor shows as two diagrams, and when processes use the whole CPU (and both cores) it shows as 200%.

The temperature is maybe normal for video encoding, the CPU is build to withstand that kind of temperature.

The more the CPU is used, the more power it consumes and radiates, the hotter it gets.

The mac minis tend to actually get hotter.. or at least mine does, particularly when i was doing processor intensive stuff. itunes, handbrake, safari, and photoshop :)

According to Intel specifications, your CPU should of been shut down the moment it reached 100C.

You are not operating at normal (or safe for that matter) temperatures.

Make sure you are not blocking the vents and the computer is sitting on a hard and flat surface. If this is already the case, take it in to the Apple immediately.

No, that is where it starts to throttle. Please don't talk out your ass.
