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. Room ambient temperatures were 23c.
We measured results with CPUID Hardware Monitor software. The CPU was loaded with Cinebench in a loop and Furmark stress test.
The processor peaks around 64C when loaded with Cinebench R11.5 64 bit on a loop test. The system does get quite warm under load and the fan has to work hard to compensate. We couldn't use any software tools to measure the temperature of the HD7970M as they would all crash or hard lock.
We attached five diodes to the back of the chassis and measured the temperature (Celcius) after one hour of intensive work and gaming.
The underside of the machine has a single ‘hot spot' at the rear which has the section housing the primary heatsink and fan.
Hot air is expelled out the side and rear vents, although some travels to the central section of the machine due to the large copper heatpipes attached to the HD7970M in this area. The remainder of the machine is quite cool to touch although we wouldn't want to be using this machine on our lap when gaming for a long period of time.
