Benchmarks: Temperature
Temperatures have been a cause for concern in older all-in-one PCs, but there are no such problems here.
Asus's internal cooling solution is working really well. With the CPU running flat-out during our benchmarks, core temperature refused to exceed 60ºC.
There's ample cooling for the GeForce GT 740M and Asus's chassis could probably handle a more-powerful GPU.
What's worth knowing is that the ET2321 achieves good cooling performance without making too much fuss. Idle system noise was measured at a gentle 34.8dB and the system barely gets any louder under load. Good engineering all round.
