What owners say

Three laboratories measured this machine's fan and reached three different conclusions. The first calls it the weakest point of the product and describes a whine that cuts through office noise, from a fan that speeds up at random while the machine sits idle. The second measured 37 to 42 dB(A) doing nothing and 54 under load. The third measured much the same figures and concluded that most people will not mind it. They do not disagree about the numbers, only about whether a constant, changing whine is something you can live with, and that is a judgement worth making before buying rather than after. The maker is no help: it publishes a noise standard of its own, under 38 dB(A) at rest, and in its own published table the row for this model has the noise and temperature cells left empty. What nobody disputes is what an hour of load does. Under a continuous processor test the chip peaks at 4.2 GHz and averages 2.0 across the hour, and the same laboratory watched the graphics side reach 100 °C. It is quick in short bursts and then settles into something a good deal slower.

For whom

Short, bursty work in a small case — office, browsing, the occasional export — for someone who will not be sitting beside it in a silent room.

Not for

Anything that loads it for an hour at a time, and quiet rooms: the fan changes speed constantly, and the laboratory that scored the noise gave it half marks.
