Dell XPS 15 (L501X): Intel Core i7 840QM/2GB nVidia GT435m Review

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.

Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by running Furmark and Cinebench together.

We placed 5 diodes on the rear to give a rough indication of how hot the machine might feel on your knee.

The cooling system is very capable, maintaining the temperatures of the CPU and GFX under 80c at all times. The rear of the chassis is also very cool, apart from the top left position (Diode 1 is in this position). The hot air is expelled from here, out the side of the chassis.
