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 Intel Core i7 3667U doesn't get too hot, peaking at 73c under extended load.
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 chassis remains relatively cool, even under load. The only warm area is close to the main exhaust vent, at the rear. The use of an Ultra Low Voltage processor was a great move from Lenovo as the ThinkPad X1 Carbon Touch could be used on the knee without discomfort.
Great laptops, bit expensive for me, but for a business user they rock. weird they haven’t released a new haswell range yet, maybe later in the year?
My boss has one of the older models, its been through the wars and still holding strong. well built.
