Here's an MSI laptop test with the same CPU (slightly different GPU)
At idle or under light workloads (browsing the Net, working with text and so), the CPU stays at around 34-38ºC and the GPU at around 30-32ºC. In these conditions the fans are audible, but not annoying, and the laptop isn’t any noisier than my Dell Studio 1537 (Intel Core 2 Duo T5800, ATI Mobility Radeon HD 3450).
After 1 h playing Call of Duty: Black Ops, the temperature of the CPU was 83ºC, and that of the GPU was 71ºC. Both the keyboard and the palmrest were only a bit warm, without being uncomfortable. In these conditions the fan noise is loud, but I didn’t find it annoying, because the speakers were loud enough.
To push the cooling system to its limits I ran simultaneously a Torture Test in Prime95 and the Stability Test in FurMark, so both CPU and GPU were at the maximum. The test was run for 1 h, and the highest recorded temperatures were 88ºC (CPU) and 77ºC (GPU). The fan speed varied depending on the temperature, so the CPU was always oscillating between 65 and 85 º C and the GPU between 73 and 76 ºC.
