Test : 1 GiB [E: 0% (0/7373 MiB)] (x5) [Interval=5 sec]

Temperatuur in gebruik: 29ºC

Aangezien andere reviews melding maken van hoge temperaturen tijdens gebruik heb ik twee temperatuursmetingen gedaan tussen de CrystalMark tests door. Bij een omgevingstemperatuur van 23ºC vindt ik 29-30ºC gemeten op de behuizing meevallen als je bedenkt dat de behuizing van de computer zelf 33ºC meet.
