Lenovo ThinkPad X1 Review (with battery slice 39+)

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.

In such a small chassis, there will be some cooling comprises made, and the CPU can get fairly hot when 100% loaded. It never crashed however over the course of a solid 8 hour loop test, reaching a maximum of 85c.

We attached 5 diodes to the machine and measured the temperatures after loading it for 90 minutes.

The ThinkPad X1 can get warm at the rear, where the hot air is expelled from inside. This can make for a slightly uncomfortable experience when placed on a lap.

We found however with the battery slice installed that much of the heat didn't transfer to the legs (as the battery makes contact rather than the underside of the X1 chassis), so there is another bonus for installing the optional battery slice !
