MSI GT780DXR 17.3″ Laptop review

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 23c – 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.

The cooling system is not as good as the one on board the Asus G74SX … as it was able to maintain 2630QM temperatures around 70c under load. The GT780DR averages around 10c higher at 82c. The motherboard also runs around 5 c hotter than the Asus G74SX machine, peaking at 52c.

We attached 5 diodes to the bottom of the machine and measured the results after 1 hour of Crysis 2 gaming.

The air vents are right above two of the heatpipes underneath and transfer the heat under the machine and to the left side (right above), close to position 1.

The hottest part of the machine is right underneath the fan system which cools both the processor and graphics card, via multiple heatpipes. It can get uncomfortable here with the machine resting on a lap, rising to 46c under extended load. Some of the heat will transfer across the top of the machine, due to the heatpipe positioning. Not the best machine to use on your knee for long periods of time.
